在.NET中,我如何设置STAThread当我在一个额外的线程运行的形式? [英] in .NET, How do I set STAThread when I'm running a form in an additional thread?
问题描述
我运行在第二个线程的形式。如果我按Ctrl-C对剪贴板复制文本,我得到一个例外,当前线程必须设置为单个线程单元(STA)可制成OLE调用之前。(使用剪贴板涉及OLE显然)。
把[STAThread]我的线程PROC,这是我的第二个线程的入口点确实的不的工作。什么工作?
[STAThread]
私人无效MyFormThreadproc(对象o)
{
形式=新建MyForm();
Application.Run(形式);
}
在创建线程,调用<一个href=\"http://msdn.microsoft.com/en-us/library/system.threading.thread.setapartmentstate.aspx\"><$c$c>SetApartmentState()$c$c>方法你开始之前。不能为线程池线程做到这一点。
例如:
线程线程=新主题(threadAction);
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
I'm running a form in a second thread. If I do Ctrl-C to copy text on the clipboard, I get an Exception, "Current thread must be set to a single thread apartment (STA) before OLE calls can be made. (Using the clipboard involves OLE apparently).
Putting the [STAThread] with my thread proc, which is the entry point of my second thread does NOT work. What will work?
[STAThread]
private void MyFormThreadproc(object o)
{
form = new MyForm();
Application.Run(form);
}
When you create the thread, call the SetApartmentState()
method before you start it. You can't do this for threadpool threads.
For example:
Thread thread = new Thread(threadAction);
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
