如何把Excel数据导入到SQL2008数据库的实例方法

 

复制代码 代码如下:

private void AddManyData_Click(object sender, RoutedEventArgs e)
       {
           OpenFileDialog openFileDialog = new OpenFileDialog();
           openFileDialog.Filter = "Excel文件|*.xls";

           if ((bool)openFileDialog.ShowDialog())  
           {  
                FileInfo fileInfo = new FileInfo(openFileDialog.FileName);  
                string filePath = fileInfo.FullName;  
                string connExcel = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties=Excel 8.0";

                using (OleDbConnection oleDbConn = new OleDbConnection(connExcel))
                {
                    oleDbConn.Open();

                    //获取excel表  
                    DataTable dt = oleDbConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                    //获取Excel表的表名 
                    string tableName = dt.Rows[0][2].ToString().Trim();
                    //去掉空格
                    tableName = "[" + tableName.Replace("'", "") + "]";

                    //利用SQL语句从Excel文件里获取数据  
                     string query = @"SELECT 学号,姓名,公益劳动,电子工艺实习,操作系统 ,计算机组成,数值分析,网络设备与集成,动态网站开发实验周,动态网站开发,均分,排名 FROM ";　　　　　　　　　　　　　　　　　　+ tableName;
                     DataSet dataSet = new DataSet();

                     using (OleDbCommand oleDbcomm = oleDbConn.CreateCommand())
                     {
                         oleDbcomm.CommandText = query;
                         OleDbDataAdapter oleAdapter = new OleDbDataAdapter(oleDbcomm);
                         oleAdapter.Fill(dataSet);
                     }
                     string connStr = "Data Source=HESHUHUA-PC;Initial Catalog=RSMSystem;Integrated Security=True";
                     //利用SqlBulkCopy批量插入数据
                    using (SqlBulkCopy sqlbc = new SqlBulkCopy(connStr))
                    {
                        sqlbc.DestinationTableName = "T_StuScore";
                        // sqlbc.ColumnMappings.Add("学号", "StuNum"),第一个参数对应数据库中的列名，
                        //第二个参数对应数据库中相应表的列名
                        sqlbc.ColumnMappings.Add("学号", "StuNum");
                        sqlbc.ColumnMappings.Add("姓名", "StuName");
                        sqlbc.ColumnMappings.Add("公益劳动", "Activity");
                        sqlbc.ColumnMappings.Add("电子工艺实习", "ElecAct");
                        sqlbc.ColumnMappings.Add("操作系统", "OprationSystem");
                        sqlbc.ColumnMappings.Add("计算机组成", "ComputerMaded");
                        sqlbc.ColumnMappings.Add("数值分析", "DataAnalyze");
                        sqlbc.ColumnMappings.Add("网络设备与集成", "NetWork");
                        sqlbc.ColumnMappings.Add("动态网站开发实验周", "WebWeek");
                        sqlbc.ColumnMappings.Add("动态网站开发", "WebMake");
                        sqlbc.ColumnMappings.Add("均分", "AvScore");
                        sqlbc.ColumnMappings.Add("排名", "StuPaiMing");
                        sqlbc.WriteToServer(dataSet.Tables[0]);
                        MessageBox.Show("数据导入成功！");

                    }
                }  

           }  

       }
