如何将数据导入到GridView使用Linq To Excel

我想从Excel导入数据到gridview 。 我已经完成了使用System.Data.OleDb

 if (ExlSheet.HasFile) { string fileName = Path.GetFileName(ExlSheet.PostedFile.FileName); string fileExtension = Path.GetExtension(ExlSheet.PostedFile.FileName); string fileLocation = Server.MapPath("~/App_Data/" + fileName); ExlSheet.SaveAs(fileLocation); if (fileExtension == ".xls") { connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\""; } else if (fileExtension == ".xlsx") { connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\""; } OleDbConnection con = new OleDbConnection(connectionString); OleDbCommand cmd = new OleDbCommand(); cmd.CommandType = System.Data.CommandType.Text; cmd.Connection = con; OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd); DataTable dtExcelRecords = new DataTable(); con.Open(); DataTable dtExcelSheetName = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); string getExcelSheetName = dtExcelSheetName.Rows[0]["Table_Name"].ToString(); cmd.CommandText = "SELECT * FROM [" + getExcelSheetName + "]"; dAdapter.SelectCommand = cmd; dAdapter.Fill(dtExcelRecords); gv.DataSource = dtExcelRecords; gv.DataBind(); } 

如何使用LinqToExcel实现相同

尝试这个

  if (ExlSheet.HasFile) { string fileName = Path.GetFileName(ExlSheet.PostedFile.FileName); string fileExtension = Path.GetExtension(ExlSheet.PostedFile.FileName); string fileLocation = Server.MapPath("~/App_Data/" + fileName); ExlSheet.SaveAs(fileLocation); ExcelQueryFactory excelFile = new ExcelQueryFactory(fileLocation); var data = from a in excelFile.Worksheet("Sheet1") select a; var columnNames = excelFile.GetColumnNames("Sheet1"); DataTable dtExcelRecords = new DataTable(); foreach (var columnName in columnNames) { dtExcelRecords.Columns.Add(columnName); } foreach (var row in data) { DataRow dr = dtExcelRecords.NewRow(); foreach (var columnName in columnNames) { dr[columnName] = row[columnName]; } dtExcelRecords.Rows.Add(dr); } gv.DataSource = dtExcelRecords; gv.DataBind(); }
