示例

以下示例演示如何使用GetLayoutSlot该方法将 a FrameworkElement 边界框转换为 。GeometryDrawing

private void getLayoutSlot1(object sender, System.Windows.RoutedEventArgs e)
{
    RectangleGeometry myRectangleGeometry = new RectangleGeometry();
    myRectangleGeometry.Rect = LayoutInformation.GetLayoutSlot(txt1);
    Path myPath = new Path();
    myPath.Data = myRectangleGeometry;
    myPath.Stroke = Brushes.LightGoldenrodYellow;
    myPath.StrokeThickness = 5;
    Grid.SetColumn(myPath, 0);
    Grid.SetRow(myPath, 0);
    myGrid.Children.Add(myPath);
    txt2.Text = "LayoutSlot is equal to " + LayoutInformation.GetLayoutSlot(txt1).ToString();
}

Private Sub getLayoutSlot1(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim myRectangleGeometry As New RectangleGeometry
    myRectangleGeometry.Rect = LayoutInformation.GetLayoutSlot(txt1)
    Dim myPath As New Path
    myPath.Data = myRectangleGeometry
    myPath.Stroke = Brushes.LightGoldenrodYellow
    myPath.StrokeThickness = 5
    Grid.SetColumn(myPath, 0)
    Grid.SetRow(myPath, 0)
    myGrid.Children.Add(myPath)
    txt2.Text = "LayoutSlot is equal to " + LayoutInformation.GetLayoutSlot(txt1).ToString()
End Sub
