页面代码：

1.引入js和css文件

　　<link href="~/Scripts/uploadify/uploadify.css" rel="external nofollow" rel="stylesheet" />
  <style type="text/css">
  #upDiv {
   width: 550px;
   height: 400px;
   border: 2px solid red;
   margin-top: 30px;
   margin-left: 50px;
   float: left;
  }
  div form {
   text-align: center;
   vertical-align: middle;
  }
  h2, h3 {
   text-align: center;
   color: #00B2EE;
  }
  #upList {
   width: 900px;
   height: 400px;
   float: left;
   margin-top: 30px;
   margin-left: 50px;
   overflow-y: scroll;
   border: 2px solid red;
  }
  #filelist {
   width: 45%;
   height: 400px;
   float: left;
  }
  #lineDiv {
   width: 50px;
   height: 400px;
   float: left;
  }
  #imglist {
   width: 45%;
   height: 400px;
   float: left;
  }
  #form1 {
   margin-top: 25px;
  }
  img {
   width: 25px;
   height: 25px;
  }
  .btn {
   width: 150px;
   height: 40px;
   text-align: center;
   background-color: #b58061;
   color: white;
  }
  p {
   cursor: pointer;
  }
 </style>
 <script src="/UploadFiles/2021-04-02/jquery-1.8.2.min.js">

2.body内代码


　　<body style="background: url(../../Images/bg.jpg) no-repeat; background-size: 1600px; width: 1600px; height: 700px; ">
 <h2 style="text-align:center;">ASP .NET MVC4 多文件文件上传实例</h2>
 <form id="form1">
  <div>
   <input type="file" id="myfile" name="myfile" />
  </div>
  <div>
   <a class="btn" href="javascript:$('#myfile').uploadify('upload');" rel="external nofollow" >上传第一个</a>
   <a class="btn" href="javascript:$('#myfile').uploadify('upload','*');" rel="external nofollow" >上传队列</a>
   <a class="btn" href="javascript:$('#myfile').uploadify('cancel');" rel="external nofollow" >取消第一个</a>
   <a class="btn" href="javascript:$('#myfile').uploadify('cancel', '*');" rel="external nofollow" >取消队列</a>
  </div>
 </form>
 <div id="upList">
  <div id="filelist">
   <h3>文件列表</h3>
  </div>
  <div id="lineDiv"></div>

  <div id="imglist">
   <h3>图片列表</h3>
  </div>
 </div>
</body>



后台代码：

   StringBuilder sb = new StringBuilder();
   DirectoryInfo theFolder = new DirectoryInfo(Server.MapPath("~/UploadFile/"));
   DirectoryInfo[] dirInfo = theFolder.GetDirectories();
