Assuming the second window is defined as <code>public partial class Window2 : Window</code>, you can do it by:

<pre><code>Window2 win2 = new Window2();
win2.Show();
</code></pre>

blocks|key|322996|text|您可以在window1中创建一个按钮并双击它。它将创建一个新的点击处理程序，在里面你可以写下这样的代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|322997|var+window2+=+new+Window2();

You can create a button in window1 and double click on it. It will create a new click handler, where inside you can write something like this:

<pre><code>var window2 = new Window2();
window2.Show();

blocks|key|540038|text|在WPF中，通过使用Show()和ShowDialog()方法，我们有几个选项。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|540039|如果你想在新窗口打开时关闭打开的窗口，那么你可以使用Show()方法：|540040|Window1+win1+=+new+Window1();
win1.Show();
win1.Close();|code-block|syntax|javascript|540041|ShowDialog()也会打开一个窗口，但在这种情况下，您不能关闭以前打开的窗口。|540042|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In WPF we have a couple of options by using the Show() and ShowDialog() methods.

Well, if you want to close the opened window when a new window gets open then you can use the Show() method:

<pre><code>Window1 win1 = new Window1();
win1.Show();
win1.Close();
</code></pre>

ShowDialog() also opens a window, but in this case you can not close your previously opened window.

blocks|key|540051|text|您可以使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|540052|private+void+OnClickNavigate(object+sender,+RoutedEventArgs+e)

You can use this code:

<pre><code>private void OnClickNavigate(object sender, RoutedEventArgs e)
{
 NavigatedWindow navigatesWindow = new NavigatedWindow();
 navigatesWindow.ShowDialog();
}
</code></pre>

blocks|key|323171|text|您需要创建一个新窗口的实例，如下所示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|323172|var+window2+=+new+Window2();|code-block|syntax|javascript|323173|一旦拥有了实例，就可以根据需要使用Show()或ShowDialog()方法。|offset|length|323174|window2.Show();|323175|或|323176|var+result+=+window2.ShowDialog();|323177|如果需要，ShowDialog()将返回一个Nullable<bool>。|style|CODE|323178|entityMap|0|LINK|mutability|MUTABLE|url|https://msdn.microsoft.com/en-us/library/system.windows.window.show%2528v=vs.110%2529.aspx|1|https://msdn.microsoft.com/en-us/library/system.windows.window.showdialog%2528v=vs.110%2529.aspx^0|0|0|H|6|0|O|C|1|0|0|0|0|M|E|0^^$0|@$1|2|3|4|5|6|7|14|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|15|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|16|8|@]|9|@$I|17|J|18|1|19]|$I|1A|J|1B|1|1C]]|A|$]]|$1|K|3|L|5|D|7|1D|8|@]|9|@]|A|$E|F]]|$1|M|3|N|5|6|7|1E|8|@]|9|@]|A|$]]|$1|O|3|P|5|D|7|1F|8|@]|9|@]|A|$E|F]]|$1|Q|3|R|5|6|7|1G|8|@$I|1H|J|1I|S|T]]|9|@]|A|$]]|$1|U|3|-4|5|6|7|1J|8|@]|9|@]|A|$]]]|V|$W|$5|X|Y|Z|A|$10|11]]|12|$5|X|Y|Z|A|$10|13]]]]

You will need to create an instance of a new window like so.

<pre><code>var window2 = new Window2();
</code></pre>

Once you have the instance you can use the <a href="https://msdn.microsoft.com/en-us/library/system.windows.window.show%28v=vs.110%29.aspx" rel="nofollow">Show()</a> or <a href="https://msdn.microsoft.com/en-us/library/system.windows.window.showdialog%28v=vs.110%29.aspx" rel="nofollow">ShowDialog()</a> method depending on what you want to do.

<pre><code>window2.Show();
</code></pre>

or

<pre><code>var result = window2.ShowDialog();
</code></pre>

ShowDialog() will return a <code>Nullable&lt;bool&gt;</code> if you need that.

blocks|key|323211|text|这对我很有帮助:+Owner方法基本上将窗口绑定到另一个窗口，以防您想要具有相同窗口的额外窗口。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|323212|LoadingScreen+lc+=+new+LoadingScreen();
lc.Owner+=+this;
lc.Show();|code-block|syntax|javascript|323213|也要考虑这一点。|323214|this.WindowState+=+WindowState.Normal;
this.Activate();|323215|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

This helped me:
The Owner method basically ties the window to another window in case you want extra windows with the same ones. 

<pre><code>LoadingScreen lc = new LoadingScreen();
lc.Owner = this;
lc.Show();
</code></pre>

Consider this as well. 

<pre><code>this.WindowState = WindowState.Normal;
this.Activate();
</code></pre>

I am new to WPF. I have two windows, such as window1 and window2. I have one button in window1. If I click that button, the window2 has to open. What should I do for that?

Here is the code I tried:

<pre><code>window2.show();
</code></pre>

How do I open a second window from the first window in WPF?

我是WPF的新手。我有两个窗口，比如window1和window2。我在window1中有一个按钮。如果我单击该按钮，window2必须打开。我该怎么做呢？下面是我尝试过的代码：window2.show();
