ASP.NET上传多个文件

HttpFileCollection与HttpPostedFile这二个类的组合就可以完成

前端

 

< asp:FileUpload ID = " FileUpload1 "  runat = " server "   />
         < br  />
         < asp:FileUpload ID = " FileUpload2 "  runat = " server "   />
         < br  />
         < asp:FileUpload ID = " FileUpload3 "  runat = " server "   />
         < br  />
         < asp:Button ID = " Button1 "  runat = " server "  onclick = " Button1_Click "  Text = " Button "   />
         < br  />
         < asp:Label ID = " Label1 "  runat = " server " ></ asp:Label >

 

后端

string  filePath  =  Server.MapPath( "" )  +   " \\UploadFiles\\ " ;

            HttpFileCollection uploadFiles  =  Request.Files;
             for  ( int  i  =   0 ; i  <  uploadFiles.Count; i ++ )
            {
                HttpPostedFile userPostFile  =  uploadFiles[i];
                     try
                    {
                         if  (userPostFile.ContentLength  >   0 )
                        {
                            userPostFile.SaveAs(filePath  +  Path.GetFileName(userPostFile.FileName));
                            Label1.Text  =   " 上传成功! " ;
                        }
                    }
                     catch  (Exception ex)
                    {
                        Label1.Text  =   " Error:  "   +  ex.Message;
                    }
            }
