我收到带有消息InvalidOperationException
的Cross-thread operation not valid..
_waitForm
在主窗体的构造函数中创建。屏幕截图中的方法是从另一个线程调用的。我虽然是BeginInvoke
解决的。我知道我正在从另一个线程(而不是创建的线程)访问表单。
关于如何解决这个问题的任何想法?
这是堆栈跟踪:

最佳答案
您是否尝试过通过以下方式对_waitForm
进行操作:
_waitForm.Invoke(new MethodInvoker(_waitForm.Hide));
或者,如果上述方法不起作用:
_waitForm.Invoke(new MethodInvoker(() =>
{
_waitForm.Reset();
_waitForm.Hide();
}));
