面向对象—在线文件管理模块

在园子里看到好多关于在线文件管理系统的文章和源代码，大家实际上达到的目的其实多大同小异，但是采用的实现的方式大有不同。

本人刚好在项目中应用到在线文件管理模块，如实自己开始写了一个Demo,当然也参考了网上高人写的代码，下面介绍我对这个模块实现的思路和实现。

 

实现思路介绍：

文件对象        FileSystemItem.cs

文件操作管理类  FileSystemManager.cs

界面            Demo.aspx

Js              jqModal.js   弹出窗口

 

文件对象

此类对文件对象的属性进行封装。

 using System;

using System.Collections.Generic;
using System.Text;

namespace FileManager

    /// <summary>

文件操作类

总结：

本人虽然从事软件开发实1年多，但是对面向对象的理解还是不太透彻，也许可能实战还不够经验不足，希望和园友一起探讨和交流,提出宝贵建议和意见。
