问题描述

protected void DownloadFile(object sender, EventArgs e)
      {
       try
       {
           string filePath = (sender as LinkButton).CommandArgument;
           Response.ContentType = ContentType;
           Response.AppendHeader("Content-Disposition", "attachment;       filename=" + Path.GetFileName(filePath));
           Response.WriteFile(filePath);
           Response.End();
       }
       catch (Exception ex)
       {
           Log(ex.Message, ex.StackTrace);

       }

   }

i am得到这个例外





线程被中止。

在System.Threading.Thread.AbortInternal（）

在System.Threading.Thread.Abort（对象stateInfo）

在System.Web.HttpResponse.End（）

在Retail_AddRetailStore.DownloadFile （对象发送者，EventArgs e）在c：\ Users \ nramaraju \Desktop \KJLSOFTWARE \Web \ Return /\\ AddRetailStore.aspx.cs：第193行

i am getting this exception


Thread was being aborted.
at System.Threading.Thread.AbortInternal()
at System.Threading.Thread.Abort(Object stateInfo)
at System.Web.HttpResponse.End()
at Retail_AddRetailStore.DownloadFile(Object sender, EventArgs e) in c:\Users\nramaraju\Desktop\KJLSOFTWARE\Web\Retail\AddRetailStore.aspx.cs:line 193

推荐答案

试试这样

Try like this

protected void lnkDownload_Click(object sender, EventArgs e)
{
LinkButton lnkbtn = sender as LinkButton;
GridViewRow gvrow = lnkbtn.NamingContainer as GridViewRow;
string filePath = gvDetails.DataKeys[gvrow.RowIndex].Value.ToString();
Response.ContentType = "image/jpg";
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filePath + "\"");
Response.TransmitFile(Server.MapPath(filePath));
Response.End();
}

参考：

Saveupload-files-in-folder-and-download.html [ ^ ]

从ASP中的GridView行下载文件.NET 4.0 [ ^ ]

这可能会有所帮助。

Refer:
Saveupload-files-in-folder-and-download.html[^]
File download from GridView rows in ASP.NET 4.0[^]
This may help.

这是正常的。您可以捕获该特定异常，然后忽略它。

This is normal. You can catch that specific exception and then ignore it.
