我在WCF上的CallbackService遇到问题.我想通过回调操作更改列表框，但是callbackservice无法使用任何形式.是否可以从callbackservice更改某些形式?我完全想在列表框中输入文本.

I have a problem with a CallbackService on WCF. I want to change a listbox from callback action, but any form isn''t available from callbackservice. Is it possible to change some forms from callbackservice? I exactly want to put text in the listbox.

推荐答案

您的CallbackService类应采用一种形式作为构造函数参数，并将其存储在字段中，以便在回调中使用方法.不要忘记使用Begin/EndInvoke(或者如果简短的话，只需使用Invoke)来更新UI控件，因为我希望在不同的线程中调用该回调. Your CallbackService class should take a form as a constructor parameter and store that in a field so it is available in callback methods. Don''t forget to use Begin/EndInvoke (or just Invoke if it''s for short things) for updating UI controls, as I would expect that that callback is called in a different thread.
