问题描述
<window> <Frame Name="myframe" NavigationUIVisibility="Hidden" Source="mypage.xaml"/> </window>
我正在尝试从包含框架(按顺序包含页面)中的窗口中获取页面实例，而我不知道如何获得.
public partial class mywindow : Window
{
public mywindow()
{
BusinessLogic.Initialize();
InitializeComponent();
var a = myframe.Content;
}
}
我如何得到它?
谢谢
推荐答案
您的代码是正确的，但缺乏内容的返回.
public partial class mywindow : Window
{
public mywindow()
{
BusinessLogic.Initialize();
InitializeComponent();
var a = (MyPage)myframe.Content;
}
}

I have a frame that i initialized in xaml like this:
<window> <Frame Name="myframe" NavigationUIVisibility="Hidden" Source="mypage.xaml"/> </window>
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;
}
}
how do i get it?
thank you
推荐答案
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;
}
}
