IniFile iniFile = new IniFile(Environment.CurrentDirectory + "\\LocalInf.ini");
//读取Local节点下M的值,默认为空值
string m  = iniFile.ReadString("Local", "M", "");
//Local节点下写F=f
iniFile.WriteString("Local", "F", "f");
//读取Local节点下IsSleep的字符串值,并转为bool类型值,给出默认值为False
 bool f = bool.Parse(iniFile.ReadString("Local", "IsSleep", "False"));
//读取Local节点下的C的字符串值,并转为double类型值,给出默认值0
 bool f = double.Parse(iniFile.ReadString("Local", "C", "0"));
