Winform中使用WPF控件并动态读取Xaml

1、添加新项

2、在构造函数中加入

    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
            Grid grid = null;
            String xamlFile = @"C:Userszgjsource
eposWindowsFormsApp1	est.xaml";
            using (FileStream fs = new FileStream(xamlFile, FileMode.Open))
            {
                grid = (Grid)XamlReader.Load(fs);
            }
            grid1.Children.Add(grid);
        }
    }

3、test.xaml内容

<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
        <StackPanel x:Name="test_panel">
            <Button x:Name="but1" Height="25" Width="60">but1</Button>
            <Button x:Name="but2" Height="25" Width="60">but2</Button>
        </StackPanel>
    </Grid>

4、将usercontrol拖到winform窗体上即可显示

 5、如果test.xaml的根节点为window，需要分离，注意加黑部分。

 /// <summary>
    /// UserControl1.xaml 的交互逻辑
    /// </summary>
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
            Window window = null;
            String xamlFile = @"C:Userszgjsource
eposWindowsFormsApp1	est.xaml";
            using (FileStream fs = new FileStream(xamlFile, FileMode.Open))
            {
                window = (Window)XamlReader.Load(fs);
            }
            Grid grid = (Grid)window.Content;
            DependencyObject parent = grid.Parent;
            if (parent != null)
            {
                parent.SetValue(ContentPresenter.ContentProperty, null);
            }
            grid1.Children.Add(grid);
        }
    }

<Window 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="test" Height="300" Width="300">
    <Grid>
        <StackPanel x:Name="test_panel">
            <Button x:Name="but1" Height="25" Width="60">but1</Button>
            <Button x:Name="but2" Height="25" Width="60">but2</Button>
        </StackPanel>
    </Grid>
</Window>
