ASP.NET生成文件以下載連接重置

Question

我想創建一個csv文件的基礎上，當用戶點擊一個按鈕的gridview的內容。但是，當我點擊按鈕時，我不斷收到Connection被服務器重置。提前致謝。

Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click 
    Try 
     Dim out As IO.TextWriter = Response.Output 
     Response.Clear() 
     Response.ClearContent() 
     Response.ClearHeaders() 
     Response.Buffer = True 
     Response.AddHeader("content-disposition", "attachment;filename=SearchResults.csv") 
     Response.Charset = "" 

     Response.ContentType = "application/text" 

     gvFiles.AllowPaging = False 
     gvFiles.DataBind() 
     Me.EnableViewState = False 
     'Bind DataTable to GridView 

     'Search() method returns a DataTable of search results 

     'gvFiles.DataSource = Search() 
     'gvFiles.DataBind() 

     'String builder class to add row data 
     Dim sb As New StringBuilder() 

     For k As Integer = 0 To gvFiles.Columns.Count - 1 

      'add separator 

      sb.Append(gvFiles.Columns(k).HeaderText & ",") 

     Next 
     'append(New line) 

     sb.Append(vbCrLf) 
     'Get Rows 
     For i As Integer = 0 To gvFiles.Rows.Count - 1 
      'Get columns 
      For k As Integer = 0 To gvFiles.Columns.Count - 1 
       'add separator 
       sb.Append(gvFiles.Rows(i).Cells(k).Text & ",") 

      Next 
      'append new line 
      sb.Append(vbCrLf) 
     Next 

     out.Write(sb.ToString()) 

     out.Flush() 

     'out.Close() 
     Response.End() 
    Catch ex As Exception 
     Response.Write("Unable to generate File" & ex.ToString()) 
    End Try 
End Sub

我找到了答案，我不得不編輯web.config連接超時等，因爲事實證明這是產生使得連接已超時大.csv文件。
