在.NET中,当我在一个额外的线程中运行表单时,如何设置STAThread? [英] in .NET, How do I set STAThread when I'm running a form in an additional thread?
问题描述
我在第二个线程中运行表单。如果我在Ctrl-C上复制剪贴板上的文本,我得到一个异常,当前线程必须设置为单线程公寓(STA)在OLE调用之前(使用剪贴板涉及OLE显然)。
将[STAThread]与我的线程proc,这是我的第二个线程的入口点不工作。 >
[STAThread]
private void MyFormThreadproc(object o)
{
form = new MyForm ;
Application.Run(form);
}
创建线程时,调用 SetApartmentState()
方法,你不能这样做的线程池线程。
例如:
线程线程= new Thread(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();
