关于RealProxy

构造函数入下：

 [SecurityCritical]
    protected RealProxy(Type classToProxy) : this(classToProxy, IntPtr.Zero, null)
    {
    }

    [SecurityCritical]
    protected RealProxy(Type classToProxy, IntPtr stub, object stubData)
    {
        if (!classToProxy.IsMarshalByRef && !classToProxy.IsInterface) throw new ArgumentException(Environment.GetResourceString("Remoting_Proxy_ProxyTypeIsNotMBR"));
        if (IntPtr.Zero == stub)
        {
            stub = _defaultStub;
            stubData = _defaultStubData;
        }
        this._tp = null;
        if (stubData == null) throw new ArgumentNullException("stubdata");
        this._tp = RemotingServices.CreateTransparentProxy(this, classToProxy, stub, stubData);
        if (this is RemotingProxy) this._flags |= RealProxyFlags.RemotingProxy;
    }

继承RealProxy的子类其构造函数中的参数classToProxy （Type类型） 必需是继承之MarshalByRef的类或者是接口
