示例

下面的代码示例演示了 Contains 方法和 SystemPens 类。 此示例旨在与 Windows 窗体一起使用。 将此代码粘贴到包含名为Button1按钮的窗体中，从窗体的构造函数或DrawFirstRectangle方法调用Load，并将该方法与按钮Button1_Click的事件相关联Click。

private:
   [UIPermission(SecurityAction::Demand, Window=UIPermissionWindow::AllWindows)]
   void DrawFirstRectangle()
   {
      Rectangle rectangle1 = Rectangle(70,70,100,150);
      ControlPaint::DrawReversibleFrame( rectangle1, SystemColors::Highlight, FrameStyle::Thick );
   }

   void Button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      Rectangle rectangle1 = Rectangle(70,70,100,150);

      // Get the bounds of the screen.
      Rectangle screenRectangle = Screen::PrimaryScreen->Bounds;

      // Check to see if the rectangle is within the bounds of the screen.
      if ( screenRectangle.Contains( rectangle1 ) )
      {
         ControlPaint::DrawReversibleFrame( rectangle1, SystemColors::Highlight, FrameStyle::Thick );

         // Call the Offset method to move the rectangle.
         rectangle1.Offset( 20, 20 );

         // Draw the new, offset rectangle.
         ControlPaint::DrawReversibleFrame( rectangle1, SystemColors::Highlight, FrameStyle::Thick );
      }
   }

Rectangle rectangle1 = new Rectangle(70, 70, 100, 150);

    if (screenRectangle.Contains(rectangle1))

        // If so, erase the previous rectangle.
    {

    ' Get the bounds of the screen.
    Dim screenRectangle As Rectangle = Screen.PrimaryScreen.Bounds

    ' Check to see if the rectangle is within the bounds of the screen.
    If (screenRectangle.Contains(rectangle1)) Then

        ' If so, erase the previous rectangle.
        ControlPaint.DrawReversibleFrame(rectangle1, _
            SystemColors.Highlight, FrameStyle.Thick)

        ' Call the Offset method to move the rectangle.
        rectangle1.Offset(20, 20)

        ' Draw the new, offset rectangle.
        ControlPaint.DrawReversibleFrame(rectangle1, _
