1、添加两个引用：WindowsFormsIntegration.dll（负责整合WPF和Windows）、System.Windows.Forms.dll

2、在 XAML文件中添加引用（粗体部分）：

<Window x:Class="VideoPreview.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:winForms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

Title="MainWindow" Height="620" Width="560">

< /Window>

 

3、在XAML编码区实现你想添加的控件：

<WindowsFormsHost Height="304" Width="540" Background="#FF00FF23" Opacity="0.2">

<winForms:PictureBox x:Name="RealPlayWnd" />

</WindowsFormsHost>
