C#操作ini配置文件和写入日志操作

调用kernel32

Code
11        [DllImport("kernel32")]
22        private static extern long WritePrivateProfileString(string section,string key, string val, string filePath);
33        [DllImport("kernel32")]
44        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
