如何保存自动生成gridview列的Excel中的数据？

我知道这可能是一个重复的问题，但我无法find任何地方。

我从excel导入数据到gridview，但如何将gridview数据保存到数据库中，并从gridview列自动生成。 数据已经反映在gridview中，我如何将它保存在数据库中？

如果有人能教我如何直接从excel插入到数据库而不使用gridview作为媒介，会更好（尝试使用这种方式，但一直告诉我excel表单不存在）。

绑定网格视图的代码：

string conStr = ""; switch (Extension) { case ".xls": //Excel 97-03 conStr = ConfigurationManager.ConnectionStrings["Excel03ConString"] .ConnectionString; break; case ".xlsx": //Excel 07 conStr = ConfigurationManager.ConnectionStrings["Excel07ConString"] .ConnectionString; break; } conStr = String.Format(conStr, FilePath, isHDR); OleDbConnection connExcel = new OleDbConnection(conStr); OleDbCommand cmdExcel = new OleDbCommand(); OleDbDataAdapter oda = new OleDbDataAdapter(); DataTable dt = new DataTable(); cmdExcel.Connection = connExcel; //Get the name of First Sheet connExcel.Open(); DataTable dtExcelSchema; dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); string SheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString(); connExcel.Close(); //Read Data from First Sheet connExcel.Open(); cmdExcel.CommandText = "SELECT * From [" + SheetName + "]"; oda.SelectCommand = cmdExcel; oda.Fill(dt); connExcel.Close(); //Bind Data to GridView GridView1.Caption = Path.GetFileName(FilePath); GridView1.DataSource = dt; GridView1.DataBind(); 

是的，我正在使用Aspsnippets的代码。

Answer 1

我最近做了这个，但我只做了fileType的Microsoft Office Excel Worksheet (.xlsx) 。 首先你必须将excel文件复制到你的应用程序目录，然后将数据保存到DataTable ，最后将其绑定到Gridview 。

使用这些命名空间

 using System.Data; using System.Data.OleDb; using System.Data.SqlClient; using System.IO; 

这是方法

 private void Import_To_GridTest(string FilePath) { DataTable dt =new DataTable(); try { string sSheetName = null; string sConnection = null; DataTable dtTablesList = default(DataTable); OleDbDataAdapter oda = new OleDbDataAdapter(); OleDbConnection oleExcelConnection = default(OleDbConnection); sConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Macro;HDR=YES;IMEX=1\""; sConnection = String.Format(sConnection, FilePath); oleExcelConnection = new OleDbConnection(sConnection); oleExcelConnection.Open(); dtTablesList = oleExcelConnection.GetSchema("Tables"); if (dtTablesList.Rows.Count > 0) { sSheetName = dtTablesList.Rows[0]["TABLE_NAME"].ToString(); } dtTablesList.Clear(); dtTablesList.Dispose(); if (!string.IsNullOrEmpty(sSheetName)) { var oleExcelCommand = oleExcelConnection.CreateCommand(); oleExcelCommand.CommandText = "Select * From [" + sSheetName + "]"; oleExcelCommand.CommandType = CommandType.Text; oda.SelectCommand = oleExcelCommand; oda.Fill(dt); oleExcelConnection.Close(); } oleExcelConnection.Close(); gridview1.DataSource = dt; gridview1.DataBind(); } catch (Exception e) { lblMsg.Text = "Unspecified Error Occured..!! <br>" + e.Message; divMsg.Attributes["class"] = "alert alert-danger"; mainDiv.Visible = true; File.Delete(FilePath); } } 

最后提交button点击事件

  protected void btnsubmit_OnClick(object sender, EventArgs e) { if (fileUpload1.HasFiles) { string FileName = Path.GetFileName(fileUpload1.PostedFile.FileName); string FolderPath = "Excels/"; // your path string FilePath = Server.MapPath(FolderPath + DateTime.Now.ToString("ddmmyyhhmmss") + FileName); // copy and save the the excel fileUpload1.SaveAs(FilePath); Import_To_GridTest(FilePath); } } 

更新 ：将数据保存到数据库使用SqlBulkCopy类

 private void SqlbulkCopy(DataTable dt) { if (dt.Rows.Count > 0) { string consString = ConfigurationManager.ConnectionStrings["Bulkcopy"].ConnectionString; using (SqlConnection con = new SqlConnection(consString)) { using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con)) { //Set the database table name sqlBulkCopy.DestinationTableName = "dbo.leads"; //[OPTIONAL]: Map the DataTable columns with that of the database table sqlBulkCopy.ColumnMappings.Add("Currunt_Company", "CuCompany"); sqlBulkCopy.ColumnMappings.Add("Currunt_Product", "CuProduct"); sqlBulkCopy.ColumnMappings.Add("Quantity", "Quantity"); sqlBulkCopy.ColumnMappings.Add("Unit_Price", "UnitPrice"); sqlBulkCopy.ColumnMappings.Add("Total_Price", "TotalPrice"); sqlBulkCopy.ColumnMappings.Add("Contect_Person", "ContectPerson"); con.Open(); sqlBulkCopy.WriteToServer(dt); con.Close(); } } } }
