代码实现：
public class ConfigFile

public waitSavaConfigObject()
{

public ConfigFile(string configFilePath) {
configFile = configFilePath;

//若文件不存在则创建一个文件，close方法用于关闭流，防止后续占用抛异常
File.Create(configFile).Close();
}
else
{
//加载配置文件到HashTable
LoadConfig();
}
}

{

}

}
}
}
}
public void SetConfig(string key,string value)
{

}
