public class VisualPanel : FrameworkElement

 protected VisualCollection Children { get; set; }

       public VisualPanel()

          Children = new VisualCollection(this);

        protected override int VisualChildrenCount

get

              return Children.Count;

        protected override Visual GetVisualChild(int index)

          return Children[index];

        protected override Size ArrangeOverride(Size finalSize)

          if (VisualChildrenCount>0)

              (Children[0] as FrameworkElement).Arrange(new Rect(0, 0, 100, 25));

          return base.ArrangeOverride(finalSize);

       }  }

添加元素,并将加入到Window窗体中

public class  VisualTest  : VisualPanel

      public  TextBlock  textblock;

        private void  TestVisual()

          textblock = new  TextBlock() { Text = "Hello", Background = Brushes.Red };              this.Children.Add(textblock);

        public  VisualTest()

         TestVisual();
