Response.End（）后执行代码

Question

我正在按钮单击生成excel文件下载。下载excel后，响应正在停止并结束。您能否建议我如何防止停止，以便用户无需刷新页面即可根据需要多次下载？

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();

    Response.ContentType = ".zip"; //YourExtensionFile 
    Response.AddHeader("Content-Length", file.Length.ToString()); 
    Response.WriteFile(file.FullName); 
    Response.TransmitFile(file.FullName); 
    Response.End();
