推荐答案

问题尚不清楚，但我想问题是关于使用非UI线程处理UI的一般问题.太糟糕了，您没有标记您的UI库(请立即进行；这符合您的利益！)，但是这种方法非常相似.

您无法从非UI线程调用与UI相关的任何操作.相反，您需要使用System.Windows.Threading.Dispatcher的Invoke或BeginInvoke方法(对于Forms或WPF)或System.Windows.Forms.Control(仅对于Forms).

在我过去的答案中，您将找到有关其工作原理的详细说明和代码示例:
Control.Invoke()与Control.BeginInvoke() [ ^ ]，

The question is not clear, but I guess the problem is the general about working with UI using non-UI thread. Too bad you did not tag your UI library (please do it now; it''s in your interest!), but the approach is very similar.

You cannot call anything related to UI from non-UI thread. Instead, you need to use the method Invoke or BeginInvoke of System.Windows.Threading.Dispatcher (for both Forms or WPF) or System.Windows.Forms.Control (Forms only).

You will find detailed explanation of how it works and code samples in my past answers:
Control.Invoke() vs. Control.BeginInvoke()[^],
