推荐答案

为什么不将处理任务移动到 BackgroundWorker [ ^ ]线程？

您创建线程，显示图像，然后启动工作人员。

在工作完成事件中，您隐藏图像。 />
这样你的用户界面仍然保持响应，任务在后台处理。



链接包含一个例子。

Why not move the processing task into a BackgroundWorker[^] thread?
You create the thread, show the image, and start the worker.
In the worker completed event, you hide the image.
That way your UI remains responsive, and the task is handled in the background.
