如何解决跨线程操作无效:从创建该线程的线程以外的其他线程访问控件"comboBoxWeb".

How to resolve the "Cross-thread operation not valid: Control ''comboBoxWeb'' accessed from a thread other than the thread it was created on." problem?

推荐答案

您的代码正在尝试访问其他线程中的UI元素；这在C#中是不允许的.将所有UI代码保留在创建控件的线程中，并将后台线程用于其他目的.可能会找到一些评论和建议

Your code is trying to access a UI element in a different thread; this is not allowed in C#. Keep all your UI code in the thread where the control is created and use background threads for other purposes. Some comments and suggestions may be found here[^].
