我已经阅读了一些在线教程，但似乎遗漏了一些东西。我试图通过将格式设置为文本来让前导 0 显示在列中。

任何建议将不胜感激。

    ''' <summary>
    ''' This is required for the grid view to export properly
    ''' </summary>
    ''' <param name="control"></param>

    Public Overrides Sub VerifyRenderingInServerForm(ByVal control As System.Web.UI.Control)
    End Sub

    Protected Overrides Sub OnInitComplete(ByVal e As System.EventArgs)

            Dim List As System.Web.UI.WebControls.GridView = CType(Page.FindControl("List"), System.Web.UI.WebControls.GridView)
            AddHandler List.RowDataBound, AddressOf RowDataBound

            List.DataSource = myList
            List.DataBind()

            Response.Clear()
            Response.ContentType = "application/vnd.ms-excel"
            HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=ExportList.xls")

            Response.Write("<style> .text {mso-number-format:\@; } </style>")

            Using strwriter As New System.IO.StringWriter
                Using htmlwriter As New HtmlTextWriter(strwriter)

                    List.RenderControl(htmlwriter)

                    HttpContext.Current.Response.Write(strwriter.ToString)
                    HttpContext.Current.ApplicationInstance.CompleteRequest()
                End Using
            End Using

    End Sub

    Protected Sub RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)

        If e.Row.RowType = DataControlRowType.DataRow Then

            e.Row.Cells(0).Attributes.Add("class", "text")

            Dim dtview As System.Data.DataRowView
            Dim dt As DateTime
            Dim intCounter As Integer

            dtview = e.Row.DataItem

            For intCounter = 0 To dtview.Row.ItemArray.Length - 1

                If TypeOf dtview.Row.Item(intCounter) Is System.DateTime Then
                    dt = dtview.Row.Item(intCounter)
                    e.Row.Cells(intCounter).Text = dt.ToLongDateString
                End If

            Next
        End If

    End Sub

【解决方案1】：

有一种更好的方法可以达到相同的效果，只需添加一行就可以了。不要使用循环创建样式表并为所有 <TD> 标签添加属性，而是直接在所有 TD 标签上应用样式。

string style = @"<style> TD { mso-number-format:\@; } </style>";

【讨论】：

这确实有效。就我而言，它会阻止某些数字格式在 Excel 中显示为日期。字符串仍然可以正常显示为文本。

【解决方案2】：

看看这个：how to Export GridView To Word Excel PDF and CSV documents

它工作正常。非常好。谢谢
