Windows Mobile 读写配置文件

读写INI:

 首先,得到当前exe的运行路径  
  ApplicationPath   =   Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);  
  下面是操作INI文件的类  

using  System;
using  System.Runtime.InteropServices;
using  System.Text;
using  System.IO;

namespace  Ini
{
    /**////   <summary>   
    ///   Ini的摘要说明。   
    ///   </summary>   
    public class IniFile
    {

        public string path;

使用方法  
  写信息文件  
  IniFile   NewIni   =   new   IniFile(ApplicationPath   +   "\\Test.ini");  
  NewIni.IniWriteValue("测试信息","测试一","1");  
   
  读取  
  IniFile   NewIni   =   new   IniFile(ApplicationPath   +   "\\Test.ini");  
  string   a   =   NewIni   .IniReadValue("测试信息","测试一");  
   
  读取结果  
  a   =   1
