在c#中实现代理或装饰器类的最短方法是什么？

public class MyProxy : DispatchProxy
{
    protected override object Invoke(MethodInfo targetMethod, object[] args)
    {
        // 在这里添加代理逻辑
        return targetMethod.Invoke(this, args);
    }
}

public class MyDecorator<T> : RealProxy
{
    private readonly T _decorated;

    public MyDecorator(T decorated)
    {
        _decorated = decorated;
    }

    public override IMessage Invoke(IMessage msg)
    {
        IMethodCallMessage methodCall = (IMethodCallMessage)msg;
        object returnValue = methodCall.MethodBase.Invoke(_decorated, methodCall.Args);
        return new ReturnMessage(returnValue, null, 0, methodCall.LogicalCallContext, methodCall);
    }
}

var proxy = DispatchProxy.Create<MyProxy, IMyInterface>();
var decorator = new MyDecorator<IMyInterface>(new MyImplementation());
