//用法：

string s;
int i;

IniFile ini;//聲明
ini = new IniFile(@"C:\Users\601\Desktop\1.ini");//實例
ini.setInt("secname1", "keyname1", i);寫入
s = ini.getInt("secname1", "keyname1", 0).ToString(); //讀出0 is default value

//IniFile類的定義
using System.Runtime.InteropServices;

class IniFile
    {
        private string pathname;
