是MarshalByRefObject的特殊？ [英] Is MarshalByRefObject special?

问题描述

.NET有一个名为远程处理，您可以在单独的应用程序域，甚至在物理机之间传递物体周围的事情。我不完全理解魔术是如何完成的，因此这个问题。

.NET has a thing called remoting where you can pass objects around between separate appdomains or even physical machines. I don't fully understand how the magic is done, hence this question.

在远程处理有传递对象围绕两个基地的方式 - 他们要么可以序列化（转换成一串字节和重建的另一端），也可以从<一个继承href="http://msdn.microsoft.com/en-us/library/system.marshalbyrefobject.aspx">MarshalByRefObject,在这种情况下，.NET使得一些透明代理和所有方法调用被转发回原始实例

In remoting there are two base ways of passing objects around - either they can be serialized (converted to a bunch of bytes and the rebuilt at the other end) or they can inherit from MarshalByRefObject, in which case .NET makes some transparent proxies and all method calls are forwarded back to the original instance.

这是pretty的清凉功效神奇。而且我不喜欢魔法编程。纵观 MarshalByRefObject的与反射我看不到任何会使其有别于任何其他典型的对象。甚至没有一个奇怪的内在属性或任何东西。因此，如何在全透明代理的东西组织起来？我能做出这样一个机制，我自己？我可以做一个替代 MyMarshalByRefObject 这将不会从 MarshalByRefObject的继承，但仍然做得一样？或者是 MarshalByRefObject的由.NET发动机本身和整个远程壮举非duplicatable由凡人？接受一些特殊待遇

This is pretty cool and works like magic. And I don't like magic in programming. Looking at the MarshalByRefObject with the Reflector I don't see anything that would set it apart from any other typical object. Not even a weird internal attribute or anything. So how is the whole transparent proxy thing organized? Can I make such a mechanism myself? Can I make an alternate MyMarshalByRefObject which would not inherit from MarshalByRefObject but would still act the same? Or is MarshalByRefObject receiving some special treatment by the .NET engine itself and the whole remoting feat is non-duplicatable by mere mortals?

推荐答案

魔术似乎是在一个特殊的 TransparentProxy 级 - .NET运行库处理它在一个特殊的方法。

The magic seems to be in a special TransparentProxy class - the .NET Runtime handles it in a special way.

我觉得 MarshalByRefObject的可能包含一些额外的内部信息，这可以帮助这一机制，但我没有看过太多到这一点。

I think that MarshalByRefObject may contain some additional internal information which can be helpful for this mechanism, but I haven't looked much into that.
