在BackgroundWorker中创建表单的实例 [英] Creating an instance of a form in a BackgroundWorker

问题描述

我想在BackgroundWorker中创建表单的新实例.我注意到，这样做时，新启动的表单将冻结.

为什么此表格冻结?我该如何解决?

Why does this form freeze? How can I get around this?

推荐答案

它冻结了，因为您在错误的线程中创建了表单-后台线程中没有运行事件循环.

It's freezing because you're creating the form in the wrong thread - there's no event loop running in the background thread.

您应仅在UI线程中创建或触摸UI元素. BackgroundWorker为此提供了一些挂钩，或者您可以使用Control.Invoke/BeginInvoke.

You should only create or touch UI elements in the UI thread. BackgroundWorker provides some hooks for this, or you can use Control.Invoke/BeginInvoke.
