示例

下面的代码示例旨在与 Windows 窗体 一起使用，它需要 PaintEventArgse，这是事件处理程序的参数Paint。 此代码执行以下操作：

• 创建纯红色画笔。

• 创建一个由四个点构成的数组来定义样条。

• 填充屏幕上的曲线。

曲线的默认紧张度为 0.5。

public:
   void FillClosedCurvePoint( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );

      //Create array of points for curve.

      Point point2 = Point(200,50);
      Point point3 = Point(250,200);
      Point point4 = Point(50,150);
      array<Point>^ points = {point1,point2,point3,point4};

      // Fill curve on screen.
      e->Graphics->FillClosedCurve( redBrush, points );
   }

public void FillClosedCurvePoint(PaintEventArgs e)
