            int HouseType = Convert.ToInt32(context.Request.Params["houseType"]);
            int HouseID = Convert.ToInt32(context.Request.Params["houseID"]);
            string  uploadPath =  HttpContext.Current.Server.MapPath(@context.Request["folder"])+"\\";  

            if (file != null)  
            {  
               if (!Directory.Exists(uploadPath))  
               {

                return false;
            }
        }
    }

以下是可选项的参数说明：（红色的属性代表常用的)

uploader

上传控件的主体文件，flash控件

默认值='uploadify.swf'

script

相对路径的后端脚本，它将处理您上传的文件。

绝对路径前缀或'/'或'http'的路径

默认值='uploadify.php'

checkScript

检查该文件是否已经选择驻留在服务器上。
没有默认值。官方例子中'check.php'是提供核心文件

scriptData

可提供URL传递参数。用来传递get参数。例如：

index.jsp?id=1&action=uploadify可以设置成：

'script': 'index.jsp',

'scriptData':{'id':1,'action':'uploadify'},

注：要设置‘method’：‘GET’.

fileDataName

您的文件在上传服务器脚本阵列的名称。
默认值='Filedata'

method

设置为发送到后端脚本的方法。要么'get'或post'。

默认值'post'

scriptAccess

folder

您想将文件保存到的路径。考虑到安全问题，一般并不在客户端设定后供服务器得到所存的路径。我试了下。这个参数好像以get的方式传递的。设定post得不到这个值。

queueID

文件队列ID。与div的id一致。参考上一篇例子的用法。

queueSizeLimit

限制在一次队列中的次数（可选定几个文件）。默认值= 999，而一次可传几个文件有 simUploadLimit属性决定。

multi

是否允许同时上传多文件，可设定true或false。

默认false。设定true时，选中的文件是当前项。

auto

选定文件后是否自动上传，可设定true或false。

默认false

fileDesc

出现在上传对话框中的文件类型描述。与fileExt需同时使用

fileExt

支持的格式，启用本项时需同时声明fileDesc。

如：‘*.rar,*.doc

sizeLimit

控制上传文件的大小，单位byte

simUploadLimit

多文件上传时，同时上传文件数目限制。默认1

一次可传几个文件。

buttonText

默认按钮的名字。默认BROWER

buttonImg

使用图片按钮，设定图片的路径即可。

hideButton

上传按钮的隐藏。true 或false。默认flase

rollover

？

width
