将数据表导出到Excel而不使用DataGrid
这是我的导出到Excel的代码。
Public Sub ExportDataTableToExcel(ByVal dt As DataTable, ByVal fileName As String) Dim response As HttpResponse = HttpContext.Current.Response ' first let's clean up the response.object response.Clear() response.Charset = "" ' set the response mime type for excel response.ContentType = "application/vnd.ms-excel" response.AddHeader("Content-Disposition", "attachment;filename=""CenterWiseCollection_" + ddlMonths.SelectedValue + "_" + ddlLeadComp.SelectedItem.Text + ".xlsx") ' create a string writer Using sw As New StringWriter() Using htw As New HtmlTextWriter(sw) ' instantiate a datagrid Dim dg As New DataGrid() dg.DataSource = dt dg.DataBind() dg.RenderControl(htw) response.Write(sw.ToString()) response.[End]() End Using End Using End Sub 我不想实例化一个datagrid ！ 如何实现它？ 如何直接传递一个数据表到Excel？
在
vb.net或C#.net，都欢迎。
请检查此代码是否适合您。 我用这个为我的项目工作正常
