什么是线程编组COM接口的首选方法？ [英] What is the preferred method of marshalling COM interfaces across threads?

问题描述

与CoMarshalInterThreadInterfaceInStream和CoGetInterfaceAndReleaseStream相比，使用GIT的利弊是什么？

有很多理由希望使用一种方法

从 MSDN ：

如果您在一个进程中的
公寓之间多次解开一个接口
指针，您可以使用
IGlobalInterfaceTable接口。

除此之外，我会说它是主要是偏好问题。

What are the pros/cons of using the GIT as opposed to CoMarshalInterThreadInterfaceInStream and CoGetInterfaceAndReleaseStream for marshalling COM interfaces across threads?

Are there strong reasons for preferring one method over the other, or is it more a matter of personal preference?

解决方案

From MSDN:

If you are unmarshaling an interface pointer multiple times between apartments in a process, you might use the IGlobalInterfaceTable interface. With other techniques, you would have to remarshal each time.

Besides that, I would say it's mostly a matter of preference.
