Aşağıdaki kod örneği, bir denetime özelliği ElementHost için Margin eşlemenin nasıl ekleneceğini gösterir.

// 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

Aşağıdaki kod örneği, bir WindowsFormsHost denetimdeki özellik için varsayılan eşlemenin nasıl değiştirilmeye devam olduğunu FlowDirection gösterir.

// The ReplaceFlowDirectionMapping method replaces the  
// default mapping for the FlowDirection property.
private void ReplaceFlowDirectionMapping()
{
    wfHost.PropertyMap.Remove("FlowDirection");

    wfHost.PropertyMap.Add(
        "FlowDirection",
        new PropertyTranslator(OnFlowDirectionChange));
}

// The OnFlowDirectionChange method translates a 
// Windows Presentation Foundation FlowDirection value 
// to a Windows Forms RightToLeft value and assigns
// the result to the hosted control's RightToLeft property.

{
    WindowsFormsHost host = h as WindowsFormsHost;
    System.Windows.FlowDirection fd = (System.Windows.FlowDirection)value;
    System.Windows.Forms.CheckBox cb = host.Child as System.Windows.Forms.CheckBox;

    cb.RightToLeft = (fd == System.Windows.FlowDirection.RightToLeft ) ? 
        RightToLeft.Yes : RightToLeft.No;
}

// The cb_CheckedChanged method handles the hosted control's
// CheckedChanged event. If the Checked property is true,
// the flow direction is set to RightToLeft, otherwise it is
// set to LeftToRight.
private void cb_CheckedChanged(object sender, EventArgs e)
{
    System.Windows.Forms.CheckBox cb = sender as System.Windows.Forms.CheckBox;

    wfHost.FlowDirection = ( cb.CheckState == CheckState.Checked ) ? 
            System.Windows.FlowDirection.RightToLeft : 
            System.Windows.FlowDirection.LeftToRight;
}

' The ReplaceFlowDirectionMapping method replaces the
' default mapping for the FlowDirection property.
Private Sub ReplaceFlowDirectionMapping()

    wfHost.PropertyMap.Remove("FlowDirection")

    wfHost.PropertyMap.Add( _
        "FlowDirection", _
        New PropertyTranslator(AddressOf OnFlowDirectionChange))
End Sub
