C# 如何将WinForm用户控件添加到WPF中，以便我可以在xaml.cs文件中引用它

我正在将WinForms项目的一部分迁移到WPF中

我想将现有的WinForms用户控件添加到WPF表单中。WinForm用户控件称为“TicketPrinter”，与WPF表单位于同一个项目中

在我的xaml中，我有这样一行：

xmlns:Printers="clr-namespace:Project.UserControls.Printers"

然后我在我的xaml中使用它：

        <WindowsFormsHost Height="430" HorizontalAlignment="Left" Margin="468,12,0,0" Name="windowsFormsHost1" VerticalAlignment="Top" Width="324">
            <Printers:TicketPrinter Printers:Name="ZapTicketPrinter">
            </Printers:TicketPrinter>
        </WindowsFormsHost> 
    </Grid>
</Window>

但是得到一个空值

我错过了什么？

如何在代码中引用名称？

提供x:name而不是printer:name

<WindowsFormsHost>
    <Printers:TicketPrinter x:Name="ZapTicketPrinter"/>
</WindowsFormsHost>

MSDN样品

使用代码隐藏

使用xaml

尝试使用以下代码：

private void LoadWFUserControl() 
{
    // Initialize a Host Control which allows hosting a windows form control on WPF. Ensure that the WindowsFormIntegration Reference is present.
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();

    // Create an object of your User control.
    MyWebcam uc_webcam = new MyWebcam();

    // Assign MyWebcam control as the host control's child.
    host.Child = uc_webcam;

    // Add the interop host control to the Grid control's collection of child controls. Make sure to rename grid1 to appr
    this.grid1.Children.Add(host);
}

private void LoadWFUserControl() 
{
    // Initialize a Host Control which allows hosting a windows form control on WPF. Ensure that the WindowsFormIntegration Reference is present.
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();

    // Create an object of your User control.
    MyWebcam uc_webcam = new MyWebcam();

    // Assign MyWebcam control as the host control's child.
    host.Child = uc_webcam;

    // Add the interop host control to the Grid control's collection of child controls. Make sure to rename grid1 to appr
    this.grid1.Children.Add(host);
}
