將文章裏的代碼整合在了一個解決方案裏，直接能夠下載測試，上代碼先css

前臺html

<%@ 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">

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
    <link href="js/uploadify/uploadify.css" rel="stylesheet" type="text/css" />
    <script src="js/uploadify/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
    <script src="js/uploadify/jquery.uploadify-3.1.js" type="text/javascript"></script>
    <script src="js/uploadify/uploadHandle2_ashx.js" type="text/javascript"></script>
</head>
<body>
    <div>
        <%--用來做爲文件隊列區域--%>
        <div id="fileQueue">
        </div>
        <input type="file" name="uploadify" id="uploadify" />
        <div>
            <a href="javascript:$('#uploadify').uploadify('upload')">上傳</a>| 
            <a href="javascript:$('#uploadify').uploadify('cancel')">取消上傳</a>
        </div>
    </div>
</body>
</html>

後臺ashx文件java

<%@ 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";
     
        //接收上傳後的文件
        HttpPostedFile file = context.Request.Files["Filedata"];
        //其餘參數
        //string somekey = context.Request["someKey"];
        //string other = context.Request["someOtherKey"];
        //獲取文件的保存路徑
        string uploadPath =
            HttpContext.Current.Server.MapPath("UploadImages" + "\\");
        //判斷上傳的文件是否爲空
        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;
        }
    }
  
}
