C# interop automation while user interacts with separate Word instance

Question

有没有一种方法可以在后台运行C＃互操作命令，这些命令在处理单独的Word文档时不会干扰用户？

Answer 1

All calls to the Office (for example, in Outlook) object model and PIA execute on Outlook's main foreground thread. The only threading model that the Office/Outlook/Word object model supports is single-threaded apartment (STA). Calling the Office/Outlook/Word object model or PIA from a background thread is not supported and can lead to errors and unexpected results in your solution.
