你能解释一下STA和MTA？ [英] Could you explain STA and MTA?

问题描述

您可以用自己的语言解释一下STA和MTA？

Can you explain STA and MTA in your own words?

此外，什么是公寓线程和他们做只涉及到COM？如果是这样，为什么？

Also, what are apartment threads and do they pertain only to COM? If so, why?

推荐答案

COM线程模型被称为公寓模式，即初始化COM对象的执行上下文与任何单个线程（单线程公寓）相关或多线程（多线程公寓）。在该模型中，一个COM对象，一旦在公寓初始化，是公寓为它的持续时间的一部分的运行时间。

The COM threading model is called an "apartment" model, where the execution context of initialized COM objects is associated with either a single thread (Single Thread Apartment) or many threads (Multi Thread Apartment). In this model, a COM object, once initialized in an apartment, is part of that apartment for the duration of it's runtime.

该STA模型用于非线程安全的COM对象。这意味着他们不处理自己的同步。一个常见的​​用途是UI组件。因此，如果另一线程需要与对象进行交互（例如，在一个形式按下一个按钮），则该消息被编组到STA线程。 Windows窗体消息泵系统是一个这样的例子。

The STA model is used for COM objects that are not thread safe. That means they do not handle their own synchronization. A common use of this is a UI component. So if another thread needs to interact with the object (such as pushing a button in a form) then the message is marshalled onto the STA thread. The windows forms message pumping system is an example of this.

如果COM对象可处理其自己的同步然后MTA模型可以使用，其中多个线程被允许与对象进行交互，而整理的呼叫。

If the COM object can handle its own synchronization then the MTA model can be used where multiple threads are allowed to interact with the object without marshalled calls.
