示例

下面的代码示例旨在与 Windows 窗体一起使用，它需要 PaintEventArgseOnPaint 事件对象。 该代码执行以下操作：

• 创建路径。

• 创建一个矩形并将该矩形添加到路径。

• 绘制屏幕的路径。

private:
   void AddRectangleExample( PaintEventArgs^ e )
   {
      // Create a GraphicsPath object and add a rectangle to it.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      Rectangle pathRect = Rectangle(20,20,100,200);
      myPath->AddRectangle( pathRect );

      // Draw the path to the screen.
      Pen^ myPen = gcnew Pen( Color::Black,2.0f );
      e->Graphics->DrawPath( myPen, myPath );
   }

private void AddRectangleExample(PaintEventArgs e)
{
             
    // Create a GraphicsPath object and add a rectangle to it.
    GraphicsPath myPath = new GraphicsPath();
    Rectangle pathRect = new Rectangle(20, 20, 100, 200);
    myPath.AddRectangle(pathRect);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Public Sub AddRectangleExample(ByVal e As PaintEventArgs)

    ' Create a GraphicsPath object and add a rectangle to it.
    Dim myPath As New GraphicsPath
    Dim pathRect As New Rectangle(20, 20, 100, 200)
    myPath.AddRectangle(pathRect)

    ' Draw the path to the screen.
    Dim myPen As New Pen(Color.Black, 2)
    e.Graphics.DrawPath(myPen, myPath)
End Sub
