推荐答案

我想在线程聊天中访问主要Form类的文本框来分配一个值。它只能在fuc方法中完成，但不能在聊天方法中完成.plzzzzzzzzzzzzz帮助我

我可以告诉你，函数访问的fun（）和控件都在同一个处理线程中，启动程序的函数可以访问控件。

I can tell you that the fun() and control that the function is accessing are in the same processing thread, the one that started the program as to why the function can access the control.

也许这会对你有帮助。
