如何在表单加载中下载asp.net中的多个文件？ [英] How to download multi files in asp.net in form load?

问题描述

先生，

告诉我使用asp.net c＃下载多个文件的步骤。我将文件名存储在字符串数组中并放入for循环，但for循环只进行一次。我附上了代码供您参考。请给我解决这个问题的方法。





[注意：由于Response.End（），它不会转到下一个值for循环增量]

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
  string  [] values = {  setup1.apk，  setup1.apk}; 
 
  for （ int  i =  0 ; i <  values.Length; i ++）
 {
 downloadfiles（values [i]）; 
} 
 
} 
 
  private   void  downloadfiles（ string  filename）
 {
 Response.Cache.SetCacheability（HttpCacheability.NoCache）; 
 Response.ClearContent（）; 
 Response.Clear（）; 
 Response.ContentType =   application / msi; 
 Response.AppendHeader（  Content-Disposition，  attachment; filename = + filename）; 
 Response.TransmitFile（Server.MapPath（ 〜/ jad /）+ filename） ; 
 
 Response.End（）; 
 
} 

解决方案

将它们作为文件存档压缩是一个可能的好选择。参见这些文章..

Hi sir,
Tell me the steps to download multi files using asp.net c#. I stored the filenames in string array and put in for loop, but for loop is going one time only. i attached the code for your reference. Kindly give me the solution for this problem.


[Note: Because of Response.End() it will not go to next value increment in for loop]

protected void Page_Load(object sender, EventArgs e)
   {
       string[] values = { "setup1.apk", "setup1.apk" };

       for (int i = 0; i < values.Length; i++)
       {
           downloadfiles(values[i]);
       }

   }

   private void downloadfiles(string filename)
   {
       Response.Cache.SetCacheability(HttpCacheability.NoCache);
       Response.ClearContent();
       Response.Clear();
       Response.ContentType = "application/msi";
       Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename);
       Response.TransmitFile(Server.MapPath("~/jad/") + filename);
     
       Response.End();

   }

解决方案

Zipping them as file archive is a probable good option.See these articles..
