这就是问题所在.为了使GUI保持响应状态，您需要在另一个线程中进行长时间的操作.

如果您遇到"crss-threading"问题，则MSDN正在等待您(阅读不错): [

That''s the problem. In order Keep the GUI responsive you need to do the long-time-taking operation in another thread.

[update]
If you have ''crss-threading'' issues then MSDN is waiting for you (have a good read): "How to: Make Thread-Safe Calls to Windows Forms Controls"[^].
