如何导入Excel到SQL未知数据

如何将从Excel中logging的未知数据导入到SQL Server

我有一个C＃基于Web的项目，用户必须上传Excel表，我需要将该Excel表中的数据存储到SQL Server。

有一个注意，用户logging是未知的，请告诉我一个方法，如何将这个未知的logging导入到SQL。

通过这种方式，我可以捕获logging并将其显示到GridView中。另外， 我也需要将它们存储到SQL中。

protected void btnUpload_Click(object sender, EventArgs e) { if (FileUpload1.HasFile) { string FileName = Path.GetFileName(FileUpload1.PostedFile.FileName); string Extension = Path.GetExtension(FileUpload1.PostedFile.FileName); string FolderPath = ConfigurationManager.AppSettings["FolderPath"]; string FilePath = Server.MapPath(FolderPath + FileName); FileUpload1.SaveAs(FilePath); Import_To_Grid(FilePath, Extension, rbHDR.SelectedItem.Text); } } private void Import_To_Grid(string FilePath, string Extension, string isHDR) { 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(); }

您可以使用SqlBulkCopy.WriteToServer方法将其获取到SQL Server中。
