我有一个在xaml中初始化的帧，如下所示:

I have a frame that i initialized in xaml like this:

<window> <Frame Name="myframe" NavigationUIVisibility="Hidden" Source="mypage.xaml"/> </window>

我正在尝试从包含c#代码的框架(依次包含页面)的窗口中获取页面实例，我不知道如何获取它.

I'm trying to get the page instance from the window that contains the frame (which in order contains the page) in c# code and i don't know how to get it.

public partial class mywindow : Window { public mywindow() { BusinessLogic.Initialize(); InitializeComponent(); var a = myframe.Content; } }

我怎么得到它?

谢谢

推荐答案

您的代码是正确的，但是缺少内容的返回.

Your code is correct, but lack cast the return of Content.

public partial class mywindow : Window { public mywindow() { BusinessLogic.Initialize(); InitializeComponent(); var a = (MyPage)myframe.Content; } }
