看著鍵盤玩老鼠

先在前端 input 加入 multiple

<inupt type=”file” name=”text” multiple>

在後端

for (int i = 0; i < Request.Files.AllKeys.Length; i++)
{
   if (Request.Files.AllKeys[i] == "test") 
   {
      if (File.Exists(ContentImage + Request.Files[i].FileName.ToString()))
      {
           Request.Files[i].SaveAs( + "1" +   Request.Files[i].FileName.ToString());                }
      else
     {
           Request.Files[i].SaveAs(ContentImage +Request.Files[i].FileName.ToString());
     }
   }
}
