示例
下面的代码示例演示如何使用 PropertyMap 属性来转换 Margin 托管 WPF 元素的属性。 有关详细信息，请参阅 演练：使用 ElementHost 控件映射属性。
// The AddMarginMapping method adds a new property mapping
// for the Margin property.
private void AddMarginMapping()
{
elemHost.PropertyMap.Add(
"Margin",
new PropertyTranslator(OnMarginChange));
}
// The OnMarginChange method implements the mapping
// from the Windows Forms Margin property to the
// Windows Presentation Foundation Margin property.
//
// The provided Padding value is used to construct
// a Thickness value for the hosted element's Margin
// property.
private void OnMarginChange(object h, String propertyName, object value)
{
ElementHost host = h as ElementHost;
Padding p = (Padding)value;
System.Windows.Controls.Button wpfButton =
host.Child as System.Windows.Controls.Button;
Thickness t = new Thickness(p.Left, p.Top, p.Right, p.Bottom );
wpfButton.Margin = t;
}
' The AddMarginMapping method adds a new property mapping
' for the Margin property.
Private Sub AddMarginMapping()
elemHost.PropertyMap.Add( _
"Margin", _
New PropertyTranslator(AddressOf OnMarginChange))
End Sub
' The OnMarginChange method implements the mapping
' from the Windows Forms Margin property to the
' Windows Presentation Foundation Margin property.
'
' The provided Padding value is used to construct
' a Thickness value for the hosted element's Margin
' property.
Private Sub OnMarginChange( _
ByVal h As Object, _
ByVal propertyName As String, _
ByVal value As Object)
Dim host As ElementHost = h
Dim p As Padding = CType(value, Padding)
Dim wpfButton As System.Windows.Controls.Button = host.Child
Dim t As New Thickness(p.Left, p.Top, p.Right, p.Bottom)
wpfButton.Margin = t
End Sub

Windows 窗体和 WPF 技术具有两种相似但不同的属性模型。 属性映射 支持两种体系结构之间的互操作。 有关详细信息，请参阅 Windows 窗体和 WPF 属性映射。
