当我运行我的代码后出现错误，然后显示它链接到每次迭代中的textBox更新。

textBox.Text = epoch.ToString();

System.Windows.Forms.dll中出现未处理的System.InvalidOperationException类型异常



调用线程无法访问此对象，因为另一个线程拥有它。



我该如何解决？

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

The calling thread cannot access this object because a different thread owns it.

How can I resolve it?

推荐答案

简单，你正在使用更多线程。但是GUI线程无法从另一个线程更新。你需要一些调用：

easy, you are using more threads. But the GUI thread cannot be updated from another thread. You need some invoking:

textBox.Invoke(new Action(()=> textBox.Text = epoch.ToString()));

这应该可以解决问题！

更新来自不同线程的值时，所有GUI组件都需要INVOKE。



好​​运。

That should do the trick!
All you GUI components need INVOKE when updating the values from a different thread.

GOOD Luck.
