Question

我在asp.net网站上有一个按钮，当我将某些值指向此错误时，会下载Excel文件。

我的代码背后如下

 Protected Sub Button4_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button4.Click
    Response.Clear()
    Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
    Response.Charset = ""
    Response.ContentType = "application/vnd.xls"
    Dim stringWrite As New System.IO.StringWriter()
    Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
    GridView6.RenderControl(htmlWrite)
    Response.Write(stringWrite.ToString())
    Response.[End]()
End Sub

aspx中的按钮如下：

<asp:Button ID="Button4" runat="server" Text="Extract RTD Raw Data" nclick="Button4_Click" 
                 BackColor="#FF9966"  CssClass="myButton" Font-Bold="True" 
                 Font-Italic="True" />

我正在获得此堆栈跟踪。

在Web.config文件中插入以下标记<machineKey validationKey="929DF4BCF13739428C8C765842BD122C653C28F688D39‌9F216942E5438AA880B4‌A793C0772A51660FDA9A‌69B079AB3B0ADFCFC149‌41F5BBD673BC72E9804D‌F44" decryptionKey="0B4443E8C132884733E8B26587FFCE50562CF8CF9980B‌AD4813A95D54A7A369B" validation="SHA1" decryption="AES" />后，没有错误。
