在一个线程中最顶层的形式？ [英] TopMost form in a thread?

问题描述

我使用下面的代码打开一个新的线程形式：

I am using the following code to open a form in a new thread:

private void button1_Click(object sender, EventArgs e)
{

    Thread thread = new Thread(ThreadProc);
    thread.Start();
}


public void ThreadProc()
{

    Form form = new Form();
    form.TopMost = true;
    form.ShowDialog();
}

不过，新创建的窗体不是最顶层，即使我将它设置为true

But the newly created form isn't TopMost even though I set it to true.

我怎样才能使一个形式，一个线程最顶层的？

How can I make a form in a thread TopMost ?

推荐答案

通常你不需要另一个线程，你打开窗体为模式或无模态模式通常，如果表单需要做一个沉重的过程，那么你做一个线程中的过程。结果

具体到你的问题一种选择是从Application.Run运行形式描述的这里。

Usually you don't need another thread, you open the form as usual in modal or non modal mode, if the form needs to do a heavy process then you do the process inside a thread.

Specific to your question one option is to run the form from an Application.Run as described here.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Thread thread = new Thread(ThreadProc);
        thread.Start();
    }


    public void ThreadProc()
    {
        using (Form1 _form = new Form1())
        {
            _form.TopMost = true;
            Application.Run(_form);
        }
    }
}

这将推出一个新的线程有自己的消息泵，并保持它作为一个最顶层的形式。

That will launch a new thread with its own message pump and will keep it as a TopMost form.
