示例

下面的示例演示如何使用代码创建 Polygon 元素并设置其属性。有关完整的示例，请参见 WPF 形状库示例。

Visual Basic

' Add a Polygon Element
Dim myPolygon As New Polygon()
myPolygon.Stroke = Brushes.Black
myPolygon.Fill = Brushes.LightSeaGreen
myPolygon.StrokeThickness = 2
myPolygon.HorizontalAlignment = HorizontalAlignment.Left
myPolygon.VerticalAlignment = VerticalAlignment.Center
Dim Point1 As New System.Windows.Point(1, 50)
Dim Point2 As New System.Windows.Point(10, 80)
Dim Point3 As New System.Windows.Point(50, 50)
Dim myPointCollection As New PointCollection()
myPointCollection.Add(Point1)
myPointCollection.Add(Point2)
myPointCollection.Add(Point3)
myPolygon.Points = myPointCollection
myGrid.Children.Add(myPolygon)

//Add the Polygon Element
myPolygon = new Polygon();
myPolygon.Stroke = System.Windows.Media.Brushes.Black;
myPolygon.Fill = System.Windows.Media.Brushes.LightSeaGreen;
myPolygon.StrokeThickness = 2;
myPolygon.HorizontalAlignment = HorizontalAlignment.Left;
myPolygon.VerticalAlignment = VerticalAlignment.Center;
System.Windows.Point Point1 = new System.Windows.Point(1, 50);
System.Windows.Point Point2 = new System.Windows.Point(10,80);
System.Windows.Point Point3 = new System.Windows.Point(50,50);
PointCollection myPointCollection = new PointCollection();
myPointCollection.Add(Point1);
myPointCollection.Add(Point2);
myPointCollection.Add(Point3);
myPolygon.Points = myPointCollection;
myGrid.Children.Add(myPolygon);
