一个对ini配置文件读写的类

namespace BaseInfo
{
    public class G_INI
    {
        // 声明INI文件的写操作函数 WritePrivateProfileString()

        public void Writue(string section, string key, string value)
        {

            // section=配置节，key=键名，value=键值，path=路径

            WritePrivateProfileString(section, key, value, sPath);

        }
        public static string ReadValue(string section, string key)
        {

            // 每次从ini中读取多少字节

            // section=配置节，key=键名，temp=上面，path=路径

            GetPrivateProfileString(section, key, "", temp, 255, sPath);

            return temp.ToString();

        }
        /// <summary>

        /// </summary>
        /// <param name="section"></param>
        /// <param name="key"></param>
        /// <returns></returns>
        public static string ReadValue(IniInfo section, IniInfo key)
        {
            // 每次从ini中读取多少字节
            System.Text.StringBuilder temp = new System.Text.StringBuilder(255);
            // section=配置节，key=键名，temp=上面，path=路径
            GetPrivateProfileString(section.ToString(), key.ToString(), "", temp, 255, sPath);
            if (temp.ToString().EndsWith("\\"))
            {
                return temp.ToString();
            }
            else
            {
                return temp.ToString() + "\\";
            }
        }

    }
}

这里请忽略最后一个方法，那是为了读一个路径的专用方法。
