jquery easyui filebox 上传附件 + asp.net后台

form必须加这个属性enctype="multipart/form-data",否则后台获取不到文件

 <script>
 function uploadFiles() {
     $('#fm').form('submit', {
                 url: 'Upload.aspx?fjssmk=Xmgl',
                 success: function (result) {
                     var result = eval('(' + result + ')');
                     //可以写一些提示的代码等等..
                 }
             });
 }
 </script>

 <form id="fm" method="post" enctype="multipart/form-data">
     <input id="upload1" class="easyui-filebox" name="file1" data-options="prompt:'选择文件...',onChange:function(){uploadFiles()}" style="width: 150px" />
 </form>

asp.net 后台代码 , 其中Sys_fjxx为一个Model文件, 可以去掉 , 对数据库的操作改成你自己的就可以了,

 public class Upload : IHttpHandler, IRequiresSessionState
     {

         public bool IsReusable
         {
             get { return false; }
         }

         public void ProcessRequest(HttpContext context)
         {
             try
             {
                 string fjssmk = context.Request["fjssmk"];
                 string userid = Utility.GetCurrentUser().zybh + "";

                 HttpFileCollection httpFileCollection = context.Request.Files;
                 HttpPostedFile file = null;
                 if (httpFileCollection.Count > )
                     file = httpFileCollection[];
                 if (file != null)

                     Sys_fjxx fjxx = ConvertFile(file);

                     exe.Add(fjxx);
                     exe.DBCommit();
