不能在初始化实例之后设置 InstanceLifetime。必须使用默认的构造函数，并在设置 RawValue 之前手动设置 CategoryName、InstanceName、CounterName、InstanceLifetime 和 ReadOnly 属性。

The InstanceLifetime cannot be set after the instance has been initialized. You must use the default constructor and set the CategoryName, InstanceName, CounterName, InstanceLifetime and ReadOnly properties manually before setting the RawValue.
