C#在新线程或任务中打开表单? [英] C# Open Form in a new Thread or Task?

问题描述

如何使用线程或任务在C#中打开新表单.

How do i open a new form in C#, with the thread or task.

示例:

public void openform()
{
    Form _form = new Form();
    _form.show()
}

Thread _thread = new Thread(openform);
_thread.start();

如果我使用线程，它将打开该表单并再次将其关闭.

if i use a Thread it opens the form and close it again.

推荐答案

只要将ApartmentState设置为STA并启动另一个消息循环，您可以创建另一个UI线程:

You can create another UI thread if you simply set the ApartmentState to STA and start another message loop:

Thread _thread = new Thread(() =>
{
    Application.Run(new Form());
});
_thread.SetApartmentState(ApartmentState.STA);
_thread.Start();

请注意，尽管如此，您将无法显示在此表单的主线程上创建的控件.这就是为什么创建多个UI线程通常是一个坏主意的原因.

Note that you wont't be able to display a control that you create on the main thread on this form though. That's why it is generally a bad idea to create more than one UI thread.
