将文章里的代码整合在了一个解决方案里，直接可以下载测试，上代码先

前台

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
    <div>
        <%--用来作为文件队列区域--%>
        <div id="fileQueue">
        </div>
        <input type="file" name="uploadify" id="uploadify" />
        <div>
            <a href="javascript:$('#uploadify').uploadify('upload')">上传</a>| 
            <a href="javascript:$('#uploadify').uploadify('cancel')">取消上传</a>
        </div>
    </div>
</body>
</html>

后台ashx文件

<%@ WebHandler Language="C#" Class="imageHandler" %>

using System;
using System.Web;
using System.IO;

public class imageHandler : IHttpHandler {

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
     
        //接收上传后的文件
        HttpPostedFile file = context.Request.Files["Filedata"];
        //其他参数
        //string somekey = context.Request["someKey"];
        //string other = context.Request["someOtherKey"];
        //获取文件的保存路径
        string uploadPath =
            HttpContext.Current.Server.MapPath("UploadImages" + "\\");
        //判断上传的文件是否为空
        if (file != null)
        {
            if (!Directory.Exists(uploadPath))
            {
                Directory.CreateDirectory(uploadPath);
            }
            //保存文件
            file.SaveAs(uploadPath + file.FileName);
            context.Response.Write("1");
        }
        else
        {
            context.Response.Write("0");
        }

    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
  
}
