Thanks in advance..
答
STA = 单线程公寓 [ ^ ]
STA = Single Thread Apartment[^]
[STAThread]是COM的结转，是Microsoft的组件对象模型，于1993年引入，用于构建软件组件的交互和创建;它是ActiveX，OLE和其他软件抽象层的骨干。请参阅：[ ^ ]。
COM提供了单线程单元（STA）和多线程（MTA）编程模型。
如果使用Microsoft Ribbon Control在Win7 / 8中，您正在使用COM组件。如果您在C＃.NET中使用Microsoft提供的控件编写WinForms，您可能正在使用通过COM和ActiveX创建的控件，现在可以与.NET进行交互。
.NET CLR使用COM Interop作为托管.NET类型和COM工具世界之间的一种桥梁，对象[ ^ ]。
深入了解[STAThread]在.NET编程中的含义，我建议你研究Hans Passant的这篇优秀论文：[ ^ ] 。
过度简化：WinForms编程需要使用[STAThread] ...当然，这并不能阻止你创建和使用其他线程，只要他们不触摸UI线程。
[STAThread] is a carry-over from COM, Microsoft's "Component Object Model," introduced in 1993 as way to structure interaction and creation of software components; it was/is the "backbone" of ActiveX, OLE, and other layers of software abstraction. See: [^].
COM provided both single-threaded apartment (STA), and multi-threaded (MTA) programming models.
If use the Microsoft Ribbon Control in Win7/8, you are using a COM component. If you use the Microsoft provided Controls in programming WinForms in C# .NET, you are probably using Controls created with COM, and ActiveX, that now inter-operate with .NET.
The .NET CLR uses COM Interop as a kind of "bridge" between the world of managed .NET Types and COM facilities, and object [^].
To get a deeper sense of what [STAThread] means in .NET programming, I suggest you study this excellent essay by Hans Passant: [^].
To over-simplify: WinForms programming requires the use of [STAThread] ... that, of course, does not stop you from creating and using other threads, as long as they don't "touch" the UI thread.
