数据导出到Excel(或Word)源代码大全
在日常工作中,大家都习惯Office作为办公软件,因此,在开发软件的时,常常会有把数据导出到Excel等Office软件的需求。在此,收集一些常用的导出文件的源程序,希望给大家带来方便。(不断更新)
一、DataSet数据集内数据转化为Excel
- // 作用:把DataSet数据集内数据转化为Excel、Word文件
- // 描述:这些关于Excel、Word的导出方法,基本可以实现日常须要,其中有些方法可以把数据导出后
- // 生成Xml格式,再导入数据库!有些屏蔽内容没有去掉,保留下来方便学习参考用之。
- // 备注:请引用Office相应COM组件,导出Excel对象的一个方法要调用其中的一些方法和属性。
- public void DataSetToExcel(DataSet ds,string FileName)
- {
- try
- {
- //Web页面定义
- //System.Web.UI.Page mypage=new System.Web.UI.Page();
- HttpResponse resp;
- resp=HttpContext.Current.Response;
- resp.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");
- resp.AppendHeader("Content-disposition","attachment;filename="+FileName+".xls");
- resp.ContentType="application/ms-excel";
- //变量定义
- string colHeaders=null;
- string Is_item=null;
- //显示格式定义////////////////
- //文件流操作定义
- //FileStream fs=new FileStream(FileName,FileMode.Create,FileAccess.Write);
- //StreamWriter sw=new StreamWriter(fs,System.Text.Encoding.GetEncoding("GB2312"));
- StringWriter sfw=new StringWriter();
- //定义表对象与行对象,同时用DataSet对其值进行初始化
- System.Data.DataTable dt=ds.Tables[0];
- DataRow[] myRow=dt.Select();
- int i=0;
- int cl=dt.Columns.Count;
- //取得数据表各列标题,各标题之间以/t分割,最后一个列标题后加回车符
- for(i=0;i<cl;i++)
- {
- //if(i==(cl-1)) //最后一列,加/n
- // colHeaders+=dt.Columns[i].Caption.ToString();
- //else
- colHeaders+=dt.Columns[i].Caption.ToString()+"/t";
- }
- sfw.WriteLine(colHeaders);
- //sw.WriteLine(colHeaders);
- //逐行处理数据
- foreach(DataRow row in myRow)
- {
- //当前数据写入
- for(i=0;i<cl;i++)
- {
- //if(i==(cl-1))
- // Is_item+=row[i].ToString()+"/n";
- //else
- Is_item+=row[i].ToString()+"/t";
- }
- sfw.WriteLine(Is_item);

- }
- resp.Write(sfw);
- //resp.Clear();
- resp.End();
- }
- catch(Exception e)
- {
- throw e;
- }

三、生成XML然后转换成Excel方式
参考资源:http://www.codeproject.com/office/Excel_Export.asp?df=100&forumid=329437&fr=51 (源程序) 优点: a. 服务端不用安装Excel程序。 b. 支持一定的Excel文件格式设置,比如字体大小、颜色、合并单元格等。 缺点: a. 与Excel 2000不兼容:由于Excel 2000不支持XML,所以以这种方法生成的Excel文件可能在Excel2000中不兼容(毕竟目前还有不少用户的电脑装的是Excel 2000)。 b. 可能不支持Excel文件页边距的设置;不支持Excel文件横向、纵向的设置;不支持Excel模板; c. 编程工作量比较大; d. 生成的文件本质上是XML文件,需要“另存为xls”才能变成真正的Excel文件。 e. 性能是好是坏还不清楚,目前还没真正在项目中用过。希望有用过此方案的朋友能介绍一下这个方案的性能。
四、导出GridView到Excel
- //导出GridView到Excel中的关键之处
- //用法: ToExcel(GVStaff, TextBox1.Text);
- public static void ToExcel(System.Web.UI.Control ctl,string FileName)
- {
- HttpContext.Current.Response.Charset ="UTF-8";
- HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default;
- HttpContext.Current.Response.ContentType ="application/ms-excel";
- HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename="+""+FileName+".xls");
- ctl.Page.EnableViewState =false;
- System.IO.StringWriter tw = new System.IO.StringWriter();
- HtmlTextWriter hw = new HtmlTextWriter(tw);
- ctl.RenderControl(hw);
- HttpContext.Current.Response.Write(tw.ToString());
- HttpContext.Current.Response.End();
- }
- 必须有下面这句!否则不会通过!
- public override void VerifyRenderingInServerForm(Control control)
- {
- // Confirms that an HtmlForm control is rendered for
- }
五、DataTable导出到Excel
- using System;
- using Microsoft.Office.Interop.Excel;
- using System.Windows.Forms;
- namespace DongVI
- {
- /// <summary>
- /// DataTable导出到Excel
- /// 整理:dongVi
- /// </summary>
- public class DataTableToExcel
- {
- private DataTableToExcel()
- {
- }
- /// <summary>
- /// 导出Excel
- /// </summary>
- /// <param name="dt">要导出的DataTable</param>
- public static void ExportToExcel(System.Data.DataTable dt )
- {
- if (dt == null) return;
- Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
- if (xlApp == null)
- {
- // lblMsg.Text = "无法创建Excel对象,可能您的电脑未安装Excel";
- MessageBox.Show( "无法创建Excel对象,可能您的电脑未安装Excel" );
- return;
- }
- System.Windows.Forms.SaveFileDialog saveDia = new SaveFileDialog();
- saveDia.Filter = "Excel|*.xls";
- saveDia.Title = "导出为Excel文件";
- if(saveDia.ShowDialog()== System.Windows.Forms.DialogResult.OK
- && !string.Empty.Equals(saveDia.FileName))
- {
- Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks;

- Microsoft.Office.Interop.Excel.Range range = null;
- long totalCount = dt.Rows.Count;
- long rowRead = 0;
- float percent = 0;
- string fileName = saveDia.FileName;
- //写入标题
- for (int i = 0; i < dt.Columns.Count; i++)
- {
- worksheet.Cells[1, i + 1] = dt.Columns[i].ColumnName;
- range = (Microsoft.Office.Interop.Excel.Range)worksheet.Cells[1, i + 1];
- //range.Interior.ColorIndex = 15;//背景颜色
- range.Font.Bold = true;//粗体
- range.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;//居中
- //加边框
- range.BorderAround(Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous, Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin, Microsoft.Office.Interop.Excel.XlColorIndex.xlColorIndexAutomatic, null);
- //range.ColumnWidth = 4.63;//设置列宽
- //range.EntireColumn.AutoFit();//自动调整列宽
- //r1.EntireRow.AutoFit();//自动调整行高
- }
- //写入内容
- for (int r = 0; r < dt.DefaultView.Count; r++)
- {
- for (int i = 0; i < dt.Columns.Count; i++)
- {
- worksheet.Cells[r + 2, i + 1] = dt.DefaultView[r][i];
- range = (Microsoft.Office.Interop.Excel.Range)worksheet.Cells[r + 2, i + 1];
- range.Font.Size = 9;//字体大小
- //加边框
- range.BorderAround(Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous, Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin, Microsoft.Office.Interop.Excel.XlColorIndex.xlColorIndexAutomatic, null);
- range.EntireColumn.AutoFit();//自动调整列宽
- }
- rowRead++;
- percent = ((float)(100 * rowRead)) / totalCount;
- System.Windows.Forms.Application.DoEvents();
- }
- range.Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlInsideHorizontal].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin;
- if (dt.Columns.Count > 1)
- {
- range.Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlInsideVertical].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin;
- }
- try
- {
- workbook.Saved = true;
- workbook.SaveCopyAs(fileName);
- }
- catch (Exception ex)
- {
- //lblMsg.Text = "导出文件时出错,文件可能正被打开!/n" + ex.Message;
- MessageBox.Show( "导出文件时出错,文件可能正被打开!/n" + ex.Message );
- return;
- }
- workbooks.Close();
- if (xlApp != null)
- {
- xlApp.Workbooks.Close();
- xlApp.Quit();
- int generation = System.GC.GetGeneration(xlApp);
- System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
- xlApp = null;
- System.GC.Collect(generation);
- }
- GC.Collect();//强行销毁
- #region 强行杀死最近打开的Excel进程
- System.Diagnostics.Process[] excelProc = System.Diagnostics.Process.GetProcessesByName("EXCEL");
- System.DateTime startTime = new DateTime();
- int m, killId = 0;
- for (m = 0; m < excelProc.Length; m++)
- {
- if (startTime < excelProc[m].StartTime)
- {
- startTime = excelProc[m].StartTime;
- killId = m;
- }
- }
- if (excelProc[killId].HasExited == false)
- {
- excelProc[killId].Kill();
- }
- #endregion
- MessageBox.Show( "导出成功!" );
- }
- }
- }
- }
六、DataTable导出到excel(2)
- StringWriter stringWriter = new StringWriter();
- HtmlTextWriter htmlWriter = new HtmlTextWriter( stringWriter );
- DataGrid excel = new DataGrid();
- System.Web.UI.WebControls.TableItemStyle AlternatingStyle = new TableItemStyle();
- System.Web.UI.WebControls.TableItemStyle headerStyle = new TableItemStyle();
- System.Web.UI.WebControls.TableItemStyle itemStyle = new TableItemStyle();
- AlternatingStyle.BackColor = System.Drawing.Color.LightGray;
- headerStyle.BackColor =System.Drawing.Color.LightGray;
- headerStyle.Font.Bold = true;
- headerStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Center;
- itemStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Center;;
- excel.AlternatingItemStyle.MergeWith(AlternatingStyle);
- excel.HeaderStyle.MergeWith(headerStyle);
- excel.ItemStyle.MergeWith(itemStyle);
- excel.GridLines = GridLines.Both;
- excel.HeaderStyle.Font.Bold = true;
- excel.DataSource = dt.DefaultView;//输出DataTable的内容
- excel.DataBind();
- excel.RenderControl(htmlWriter);
- string filestr = "d://data//"+filePath; //filePath是文件的路径
- int pos = filestr.LastIndexOf( "//");
- string file = filestr.Substring(0,pos);
- if( !Directory.Exists( file ) )
- {
- Directory.CreateDirectory(file);
- }
- System.IO.StreamWriter sw = new StreamWriter(filestr);
- sw.Write(stringWriter.ToString());
- sw.Close();
七、通过SQL直接导出到Excel数据库
- exec master..xp_cmdshell @# bcp "SELECT au_fname, au_lname FROM pubs..authors ORDER BY au_lname" queryout c:/test.xls -c -S"soa" -U"sa" -P"sa" @#
注意:参数的大小写,另外这种方法写入数据的时候没有标题。
关于通过SQL读取EXCEL的方法请参见:http://blog.csdn.net/wonsoft/archive/2008/11/16/3312320.aspx
八、用OleDB 把 DataSet 数据导出到 Excel文件里
- //dt为数据源(数据表)
- //ExcelFileName 为要导出的Excle文件
- //ModelFile为模板文件,该文件与数据源中的表一致。否则数据会导出失败。
- //ModelFile文件里,需要有一张 与 dt.TableName 一致的表,而且字段也要一致。
- //注明:如果不用ModelFile的话,可以用一个空白Excel文件,不过,要去掉下面创建表的注释,让OleDb自己创建一个空白表。
- public static string TableToExcelFile(DataTable dt,string ExcelFileName,string ModelFile)
- {
- File.Copy(ModelFile,ExcelFileName); //复制一个空文件,提供写入数据用
- if(File.Exists(ExcelFileName)==false)
- {
- return "系统创建临时文件失败,请与系统管理员联系!";
- }
- if(dt == null)
- {
- return "DataTable不能为空";
- }
- int rows = dt.Rows.Count;
- int cols = dt.Columns.Count;
- StringBuilder sb;
- string connString;
- if(rows == 0)
- {
- return "没有数据";
- }
- sb = new StringBuilder();
- connString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ExcelFileName+";Extended Properties=Excel 8.0;";
- //生成创建表的脚本
- //----sb.Append("DROP TABLE "+dt.TableName);
- /*
- sb.Append("CREATE TABLE ");
- sb.Append(dt.TableName + " ( ");
- for(int i=0;i<cols;i++)
- {
- if(i < cols - 1)
- sb.Append(string.Format("{0} varchar,",dt.Columns[i].ColumnName));
- else
- sb.Append(string.Format("{0} varchar)",dt.Columns[i].ColumnName));
- }
- */
- //return sb.ToString();
- OleDbConnection objConn = new OleDbConnection(connString);
- OleDbCommand objCmd = new OleDbCommand();
- objCmd.Connection = objConn;
- //objCmd.CommandText=sb.ToString();
- try
- {
- objConn.Open();
- //objCmd.ExecuteNonQuery();
- }
- catch(Exception e)
- {
- return "在Excel中创建表失败,错误信息:" + e.Message;
- }
- sb.Remove(0,sb.Length);
- sb.Append("INSERT INTO ");
- sb.Append(dt.TableName + " ( ");
- for(int i=0;i<cols;i++)
- {
- if(i < cols - 1)
- sb.Append(dt.Columns[i].ColumnName + ",");
- else
- sb.Append(dt.Columns[i].ColumnName + ") values (");
- }
- for(int i=0;i<cols;i++)
- {
- if(i < cols - 1)
- sb.Append("@" + dt.Columns[i].ColumnName + ",");
- else
- sb.Append("@" + dt.Columns[i].ColumnName + ")");
- }
- //建立插入动作的Command
- objCmd.CommandText = sb.ToString();
- OleDbParameterCollection param = objCmd.Parameters;
- for(int i=0;i<cols;i++)
- {
- param.Add(new OleDbParameter("@" + dt.Columns[i].ColumnName, OleDbType.VarChar));
- }
- //遍历DataTable将数据插入新建的Excel文件中
- foreach (DataRow row in dt.Rows)
- {
- for (int i=0; i<param.Count; i++)
- {
- param[i].Value = row[i];
- }
- objCmd.ExecuteNonQuery();
- }
- return "数据已成功导入Excel";
- }
- // Trackback: http://tb.blog.csdn.net/TrackBack.aspx?PostId=754176
九、利用OLEDB,以excel为数据库,把dataset中的数据导入到excel文件中
- public static void exportToExcelByDataset(string filePath, DataSet ds,XmlNode node)
- {
- string sqlstr;
- if(fi.Exists)
- {
- fi.Delete();
- //throw new Exception("文件删除失败");
- }
- else
- {
- fi.Create();
- }
- string mailto:sqlcon=@%22Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended ProPerties=Excel 8.0;";
- OleDbConnection olecon = new OleDbConnection(sqlcon);
- OleDbCommand olecmd = new OleDbCommand();
- olecmd.Connection = olecon;
- olecmd.CommandType = CommandType.Text;
- try
- {
- olecon.Open();
- XmlNode nodec=node.SelectSingleNode("./Method/ShowField");
- int ii = 0;
- sqlstr = "CREATE TABLE sheet1(";
- foreach(XmlNode xnode in nodec.ChildNodes )
- {
- if(ii == nodec.ChildNodes.Count - 1)
- {
- if(xnode.Attributes["type"].Value.ToLower() == "int"||xnode.Attributes["type"].Value.ToLower() == "decimal")
- {
- sqlstr=sqlstr + xnode.Attributes["displayname"].Value + " number)";
- }
- else
- {
- sqlstr=sqlstr + xnode.Attributes["displayname"].Value + " text)";
- }
- // sqlstr=sqlstr + xnode.Attributes["displayname"].Value + " text)";
- }
- else
- {
- if(xnode.Attributes["type"].Value.ToLower() == "int"||xnode.Attributes["type"].Value.ToLower() == "decimal")
- {
- sqlstr=sqlstr + xnode.Attributes["displayname"].Value + " number,";
- }
- else
- {
- sqlstr=sqlstr + xnode.Attributes["displayname"].Value + " text,";
- }
- }
- // sqlstr =sqlstr + xnode.Attributes["displayname"].Value + " text";
- ii++;
- }
- olecmd.CommandText = sqlstr;
- olecmd.ExecuteNonQuery();
- for(int i=0;i<ds.Tables[0].Rows.Count;i++)
- {
- sqlstr = "INSERT INTO sheet1 VALUES(";
- int jj=0;
- foreach(XmlNode inode in nodec.ChildNodes )
- {
- if(jj == nodec.ChildNodes.Count-1)
- {
- if(inode.Attributes["type"].Value.ToLower() == "int"||inode.Attributes["type"].Value.ToLower() == "decimal")
- {
- sqlstr = sqlstr + isnull(ds.Tables[0].Rows[i].ItemArray[jj].ToString()) + ")" ;
- }
- else
- {
- sqlstr = sqlstr + "\'" + isnull(ds.Tables[0].Rows[i].ItemArray[jj].ToString().Replace("\'","\'\'")) + "\')" ;
- }
- }
- else
- {
- if(inode.Attributes["type"].Value.ToLower() == "int"||inode.Attributes["type"].Value.ToLower() == "decimal")
- {
- sqlstr = sqlstr + isnull(ds.Tables[0].Rows[i].ItemArray[jj].ToString()) + "," ;
- }
- else
- {
- sqlstr = sqlstr + "\'" + isnull(ds.Tables[0].Rows[i].ItemArray[jj].ToString().Replace("\'","\'\'")) + "\'," ;
- }
- }
- jj++;
- }
- olecmd.CommandText = sqlstr;
- olecmd.ExecuteNonQuery();
- }
- MessageBox.Show(@"Excel文件:" + filePath + " 导出成功!");
- }
- catch(Exception ex)
- {
- MessageBox.Show(ex.Message);
- }
- finally
- {
- olecmd.Dispose();
- olecon.Close();
- olecon.Dispose();
- }
- }
- // 判断对象为空
- private static string isnull(string obj)
- {
