How to add WinForm User Control Into WPF so that I can reference it in the xaml.cs file
提问by Paul H
I am migrating part of a WinForms project into WPF.
我正在将 WinForms 项目的一部分迁移到 WPF。
I want to add an existing WinForms User Control into a WPF Form. The WinForm user control is called "TicketPrinter" and lives in the same project as the WPF form.
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 表单位于同一项目中。
In my xaml I have this line:
在我的 xaml 中有这一行：
xmlns:Printers="clr-namespace:Project.UserControls.Printers"
And then I use it in my xaml here:
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>
When I run the project the user control appears on the form as expected.
当我运行项目时，用户控件按预期出现在表单上。
But when I go into the code behind xaml.cs file and try to access "ZapTicketPrinter" it is not available as a reference.
但是当我进入 xaml.cs 文件后面的代码并尝试访问“ZapTicketPrinter”时，它不能作为参考。
i.e.
IE
I try using ZapTicketPrinter and it's not recognised.
我尝试使用 ZapTicketPrinter，但无法识别。
I've also tried the following:
我还尝试了以下方法：
TicketPrinter ticketPrinter = this.FindName("ZapTicketPrinter") as TicketPrinter;
but get a null
但得到一个空值
What am I missing? How do I reference the name in my code?
我错过了什么？如何在我的代码中引用名称？
采纳答案by JSJ
provide x:Name instead of printer:name
提供 x:Name 而不是 printer:name
<WindowsFormsHost>
<Printers:TicketPrinter x:Name="ZapTicketPrinter"/>
</WindowsFormsHost>

Try using following code:
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);
}
