它在stackPanel.width stackPanel.height的wpf代码中给出了错误。同样的错误是我的标题

wpf

using System.Windows.Controls;
using System.Windows.Forms.Integration;
using WindowsFormsApplication1;

 namespace Wpfhost
 {
      /// <summary>
     /// Interaction logic for Page1.xaml
     /// </summary>
       public  partial class Page1 : Page

         private readonly Form1 mainForm = new Form1();

         public Page1()
         {
            InitializeComponent();

             //Create a Windows Forms Host to host a form
             WindowsFormsHost windowsFormsHost = new WindowsFormsHost();

             StackPanel.Width = mainForm.Width;
             StackPanel.Height = mainForm.Height;
             windowsFormsHost.Width = mainForm.Width;
              windowsFormsHost.Height = mainForm.Height;

               mainForm.TopLevel = false;

               windowsFormsHost.Child = mainForm;

               StackPanel.Children.Add(windowsFormsHost);
    }
}

}

它在stackPanel.width stackPanel.height。

的wpf代码中给出了错误

在后面的代码中，您应该使用在XAML代码中创建的StackPanel实例。在您的情况下，它是stackPanel（Name="stackPanel"）：

public Page1()
{
    InitializeComponent();

    //Create a Windows Forms Host to host a form
    WindowsFormsHost windowsFormsHost = new WindowsFormsHost();

    stackPanel.Width = mainForm.Width;
    stackPanel.Height = mainForm.Height;
    windowsFormsHost.Width = mainForm.Width;
    windowsFormsHost.Height = mainForm.Height;

    mainForm.TopLevel = false;  
    windowsFormsHost.Child = mainForm;  
    stackPanel.Children.Add(windowsFormsHost);
}

非静态字段，方法或属性'system.windows.frameworkelement.width.get'需要对象引用
