代码如下:
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.IO;
using System.Text;
using System.Reflection;
namespace Krystalware.SlickUpload
{
/**
* [[服务器端WebConfig.XML设置]]
*
* 需要在WebConfig.XML中进配置，以下结于
*<configuration>
<appSettings>
<add key="HttpUploadModulePageGoOn" value="*.*;"/>
<add key="HttpUploadModulePageJump" value="x.aspx;"/>
</appSettings>
*<system.web>
<httpModules>
<add name="HttpUploadModule" type="SlickUpload.HttpUploadModule, SlickUpload" />
</httpModules>
<httpRuntime maxRequestLength="1000000" />
*</system.web>
*</configuration>
*
[说明]
1、如果满足<HttpUploadModulePageJump>所设置的页面，则不使用大文件上传功能，直接跳出
/// 当没有设置[HttpUploadModulePageJump]则返回false;
/// 当设置[HttpUploadModulePageJump]中有[*.*;]时则返回true
/// 当设置[HttpUploadModulePageJump]中的页面等同与所要处理页面的后缀时，则返回true,否则返回false
2、如果不满足<HttpUploadModulePageJump>所设置的页面则继续进行下一判断.
3、如果满足<HttpUploadModulePageGoOn>所设置的页面，则使用大文件上传功能;否则跳出
/// 当没有设置[HttpUploadModulePageGoOn]则返回false;
/// 当设置[HttpUploadModulePageGoOn]中有[*.*;]时则返回true
/// 当设置[HttpUploadModulePageGoOn]中的页面等同与所要处理页面的后缀时，则返回true,否则返回false
