blocks|key|5778274|text|馊主意。线程池线程的生命周期由它执行的代码决定，最好是短的和快的。这不是STA线程的规则，只要在该线程上创建的COM对象尚未完成，它就必须保持活动状态并产生一个消息循环。这是一个与TP线程非常不兼容的需求。不管怎样，尝试这样做只会给你带来永无止境的痛苦，"COM对象已经从它的底层RCW中分离出来，不能使用“异常以及死锁。这就是为什么MTA线程总是.NET的原因。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5778275|您必须使用常规线程。|5778276|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

That's a bad idea. The lifetime of a threadpool thread is determined by the code it executes, preferably short and snappy. This is not the rule for an STA thread, it must stay active and pump a message loop as long as the COM objects that were created on that thread are not finalized. A requirement that's very incompatible with a TP thread. Trying to do this anyway will just buy you never-ending misery with "COM object that has been separated from its underlying RCW cannot be used" exceptions as well as deadlock. This is why a .NET tp thread is always MTA.

You must use a regular Thread.

blocks|key|3101059|text|我分析了源代码，发现SmartThreadPool不支持STA线程。创建它们的唯一方法是修改源代码，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3101060|3101061|将StartSTAThreads属性添加到STPStartInfo类。|ordered-list-item|3101062|添加|3101063|3101064|if+(_stpStartInfo.StartSTAThreads)+{+workerThread.SetApartmentState(ApartmentState.STA)；}|3101065|在workerThread.Start()调用之前添加到SmartThreadPool.StartThreads方法。|3101066|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|P|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|Q|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|R|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

I have analyzed the source code and found out that SmartThreadPool doesn't support STA threads. The only way to create them is to modify the sources as follows:

<ol>
<li>Add StartSTAThreads property to the STPStartInfo class.</li>
<li>Add 

<pre><code>if (_stpStartInfo.StartSTAThreads) 
{
 workerThread.SetApartmentState(ApartmentState.STA);
}
</code></pre></li>
</ol>

to the SmartThreadPool.StartThreads method before workerThread.Start() call.

blocks|key|5778286|text|为了完整性，current+version确实支持STA线程：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5778287|STPStartInfo+stpStartInfo+=+new+STPStartInfo();

For completeness, the <a href="http://www.codeproject.com/Articles/7933/Smart-Thread-Pool#Feature29" rel="nofollow">current version</a> does support STA threads:

<pre><code>STPStartInfo stpStartInfo = new STPStartInfo();
stpStartInfo.ApartmentState = ApartmentState.STA;
SmartThreadPool stp = new SmartThreadPool(stpStartInfo);
</code></pre>

I am using SmartThreadPool by Ami Bar 
<a href="http://www.codeproject.com/KB/threads/smartthreadpool.aspx" rel="nofollow">http://www.codeproject.com/KB/threads/smartthreadpool.aspx</a>

Although it is mentioned there that STA threads can be spawned, but i couldn't find an example. I want to create all STA threads in my pool.

我正在使用Ami Bar 的SmartThreadPool虽然这里提到了STA线程可以派生，但我找不到一个例子。我想在我的池中创建所有STA线程。
