最近想练习一下批量插入数据,所以从网上找了一下资料,做了一个怎么把Excel文件数据导入到数据库。
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!"); } } } }
