我写的一个xml配置类

一直不喜欢.net自带的配置类，所以本着自已动手，丰衣足食的思想自已写了一个配置类，也可以满足大多数的需求了。

  1using System;
  2using System.IO;
  3using System.Xml;

  5namespace ******.Utils

使用方法：

XmlConfiguration config = new XmlConfiguration("config.xml");
//写
config.WriteValue("/config/url","http://www.sina.com.cn");
//读
string value = config.ReadValue("/config/url");
