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：

• 创建一个由七个点构成的数组（表示两条连接的贝塞尔曲线）。

• 创建路径并将一系列 Bézier 曲线点添加到路径。

• 绘制屏幕的路径。

private:
   void AddBeziersExample( PaintEventArgs^ e )
   {
      // Adds two Bezier curves.
      array<Point>^ myArray = {Point(20,100),Point(40,75),Point(60,125),Point(80,100),Point(100,50),Point(120,150),Point(140,100)};

      // Create the path and add the curves.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddBeziers( myArray );

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

private void AddBeziersExample(PaintEventArgs e)
{
             
    // Adds two Bezier curves.
    Point[] myArray =
             {
                 new Point(20, 100),
                 new Point(40, 75),
                 new Point(60, 125),
                 new Point(80, 100),
                 new Point(100, 50),
                 new Point(120, 150),
                 new Point(140, 100)
             };
             
    // Create the path and add the curves.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddBeziers(myArray);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Public Sub AddBeziersExample(ByVal e As PaintEventArgs)

    ' Adds two Bezier curves.
    Dim myArray As Point() = {New Point(20, 100), New Point(40, 75), _
    New Point(60, 125), New Point(80, 100), New Point(100, 50), _
    New Point(120, 150), New Point(140, 100)}
    Dim myPath As New GraphicsPath
    myPath.AddBeziers(myArray)
    Dim myPen As New Pen(Color.Black, 2)
    e.Graphics.DrawPath(myPen, myPath)
End Sub

注解

points 参数指定连接的曲线的终结点和控制点数组。 第一条曲线使用第二和第三个点作为控制点，从第一个点构造到 points 数组中的第四个点。 除了上一条曲线的端点外，序列中的每个后续曲线还需要三个点：序列中的接下来两个点是控制点，第三个是添加曲线的端点。

如果图中有上一条线或曲线，则会添加一条线，用于将上一段的端点连接到序列中第一条立方曲线的起点。
