调用方法：
int ibaudrate = inihelper.readconfig(com_setup, 波特率)
inihelper类：
public class inihelper
{
private static string filename = application.startuppath + \\appconfig.ini;
///
/// 读取配置文件
///
///
///
///
///
public static t readconfig(string section, string key)
{

string value = f.readcontentvalue(section, key);
if (string.isnullorwhitespace(value))
return default(t);
if (typeof(t).isenum)
return (t)enum.parse(typeof(t), value, true);
return (t)convert.changetype(value, typeof(t));
}
else
{
return default(t);
}
}
///

//如果文件不存在，则创建
if (!file.exists(filename))

using (filestream myfs = new filestream(filename, filemode.create)) { }
}
inifile f = new inifile(filename);
f.writecontentvalue(section, key, value);
