public class INIConfigHelper
    
        public string Path;     //INI文件名
        [DllImport("kernel32")]
        private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

        //声明读写INI文件的API函数     
        public INIConfigHelper(string iniPath)
        
            Path = iniPath;
        

        //类的构造函数，传递INI文件名
        public void IniWriteValue(string section, string key, string value)
        
            WritePrivateProfileString(section, key, value, this.Path);
        

        //读INI文件         
        public string IniReadValue(string section, string key)
        
            var temp = new StringBuilder(256);
            int i = GetPrivateProfileString(section, key, "", temp, 256, this.Path);
            return temp.ToString();
        
    

private INIConfigHelper configReader = new INIConfigHelper(string.Concat(AppDomain.CurrentDomain.BaseDirectory, "Config\\Counter.ini"));

读取节点：
string section = "time";
                string startTimeStr = configReader.IniReadValue(section, "start");

更新节点：
configReader.IniWriteValue("time", "start", maxTime.ToString("yyyy-MM-dd HH:mm:ss"));
