代碼如下:
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
{
/**
* [[服務器端WebConfig.XML設置]]
*
* 需要在WebConfig.XML中進配置，以下結于
*<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>
*
[說明]
1、如果滿足<HttpUploadModulePageJump>所設置的頁面，則不使用大文件上傳功能，直接跳出
/// 當沒有設置[HttpUploadModulePageJump]則返回false;
/// 當設置[HttpUploadModulePageJump]中有[*.*;]時則返回true
/// 當設置[HttpUploadModulePageJump]中的頁面等同與所要處理頁面的后綴時，則返回true,否則返回false
2、如果不滿足<HttpUploadModulePageJump>所設置的頁面則繼續進行下一判斷.
3、如果滿足<HttpUploadModulePageGoOn>所設置的頁面，則使用大文件上傳功能;否則跳出
/// 當沒有設置[HttpUploadModulePageGoOn]則返回false;
/// 當設置[HttpUploadModulePageGoOn]中有[*.*;]時則返回true
/// 當設置[HttpUploadModulePageGoOn]中的頁面等同與所要處理頁面的后綴時，則返回true,否則返回false
