Generally you need to host your form in a WindowInteropHelper, like following in the WPF window Button.Click event handler:
通常，您需要在WindowInteropHelper 中托管您的表单，如下面的 WPF 窗口 Button.Click 事件处理程序：
C#:
C＃：
private void button1_Click(object sender, RoutedEventArgs e) {
Form1 form = new Form1();
WindowInteropHelper wih = new WindowInteropHelper(this);
wih.Owner = form.Handle;
form.ShowDialog();
}
VB:
VB：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click
Dim form As New Form1()
Dim wih As New WindowInteropHelper(Me)
wih.Owner = Form.Handle
form.ShowDialog()
End Sub
And of course you need to add reference/import of your project and System.Windows.Forms.dll
当然，您需要添加项目和 System.Windows.Forms.dll 的引用/导入

it is impossible loading a win form from WPF application. so you can do like this:
不可能从 WPF 应用程序加载 win 表单。所以你可以这样做：
1- Create a User control in winform project and add all form's element to user control
1-在winform项目中创建一个用户控件并将所有表单元素添加到用户控件中
public partial class myUserControl : UserControl, IDisposable
{
...// All Form Code and element put here
}
2- create a wpf window and put a Grid into that:
2- 创建一个 wpf 窗口并将一个 Grid 放入其中：
<Grid Name="grid">
</Grid>
3- on Wpf window Code behind like this :
3- 在 Wpf 窗口后面的代码如下：
public partial class myWpfWindow: Window
{
public myWpfWindow()
{
InitializeComponent();
myUserControl = new myUserControl ();
System.Windows.Forms.Integration.WindowsFormsHost winformHost = new
System.Windows.Forms.Integration.WindowsFormsHost();
winformHost.Child = myUserControl;
grid.Children.Add(winformHost); // --> <Grid Name="grid">
}
}
4- add two reference to project:WindowsFormsIntegration, System.Windows.Forms
4- 添加两个对项目的引用：WindowsFormsIntegration, System.Windows.Forms
