推荐答案

为什么？

为什么不只是：

Why?
Why not just:

private void button1_Click(object sender, EventArgs e)
{
    Form2 frm2 = new Form2();
    Hide();
    frm2.ShowDialog();
    Close();
}

为什么不阅读原始MSDN文档？



所有你需要的是这： http://msdn.microsoft.com /en-us/library/system.windows.window.close(v=vs.110).aspx [ ^ ]。



参见：

http://msdn.microsoft.com/en-us/library/system.windows.uielement.isvisible(v = vs.110）.aspx [ ^ ]，

http://msdn.microsoft。 COM / EN-US /库/ system.windows.window.show（ v = vs.110）.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.windows.window.hide（v = vs.110）的.aspx [ ^ ]。



请参阅此处的生命周期管理小节： http://msdn.microsoft.com/en-us/library/system.windows.window%28v= vs.110％29.aspx [ ^ ]。



无论从何处调用它，从什么方法都无关紧要窗口，或不是一个窗口（一旦它是calle d来自同一个UI线程）。此外，没有父窗口这样的东西。有一个主窗口，拥有窗口...

Why not reading original MSDN documentation?

All you need is this: http://msdn.microsoft.com/en-us/library/system.windows.window.close(v=vs.110).aspx[^].

See the sub-section "Lifetime Management" here: http://msdn.microsoft.com/en-us/library/system.windows.window%28v=vs.110%29.aspx[^].

It does not matter from where it is called from, from a method of what window, or not a window (as soon as it is called from the same UI thread). Besides, there is no such thing as "parent" window. There is a main window, owned window…
