        [DllImport("kernel32")]

        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

        private string iniFileName;

        //private bool bDisposed = false;

        public clsINI(string xfilepath)

        {

            iniFileName = xfilepath;

        }

        public void WriteIni(string section, string key, string val)

        {

            WritePrivateProfileString(section, key, val, iniFileName);

        }

        public string ReadIni(string section, string key)

        {

            StringBuilder temp = new StringBuilder(255);
