ASP.NET MVC4 利用uploadify.js多文件上传

页面代码：

1.引入js和css文件

　　
  
  #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;
  }
