在Response.End（）之后执行代码

Question

我在按钮点击时生成excel文件下载。下载excel后，响应将停止并结束。您能否建议我如何阻止停止，以便用户可以在不刷新页面的情况下多次下载？

Response.Clear();
Response.ContentType = 
  "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader
(
  "content-disposition", 
  "attachment;  filename=PFMWarehouseList_" 
  + DateTime.Today.ToString("dd/MM/yyyy") + ".xlsx"
);

Response.BinaryWrite(pck.GetAsByteArray());

//HttpContext.Current.ApplicationInstance.CompleteRequest();
Response.End();

string Url = "FullPatchYourFile";
FileInfo file = new FileInfo(Url);

try
{
    Response.Clear();
    Response.ClearHeaders();
    Response.ClearContent();
    Response.AddHeader("content-disposition", "attachment;filename=YourFileName");
    Response.AddHeader("Content-Type", "application/zip"); 
    Response.ContentType = ".zip"; //YourExtensionFile
    Response.AddHeader("Content-Length", file.Length.ToString());
    Response.WriteFile(file.FullName);
    Response.TransmitFile(file.FullName);
    Response.End();
}
finally
{
    Your instructions after response.end();
