参数

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：

• 创建描述三角形的四个点的数组。

• 创建路径并添加行数组。

• 绘制屏幕的路径。

请注意，第一个点后面的每一行都使用上一个点作为起点，新点作为终结点。

private:
   void AddLinesExample( PaintEventArgs^ e )
   {
      // Create a symetrical triangle using an array of points.
      array<Point>^ myArray = {Point(30,30),Point(60,60),Point(0,60),Point(30,30)};

      //Create a path and add lines.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddLines( myArray );

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

private void AddLinesExample(PaintEventArgs e)
{
             
    // Create a symmetrical triangle using an array of points.
    Point[] myArray =
             {
                 new Point(30,30),
                 new Point(60,60),
                 new Point(0,60),
                 new Point(30,30)
             };
             
    //Create a path and add lines.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddLines(myArray);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Public Sub AddLinesExample(ByVal e As PaintEventArgs)

    'Create a symmetrical triangle using an array of points.
    Dim myArray As Point() = {New Point(30, 30), New Point(60, 60), _
    New Point(0, 60), New Point(30, 30)}
    Dim myPath As New GraphicsPath
    myPath.AddLines(myArray)

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

注解

如果图中有上一条线或曲线，则会添加一条线来连接上一段的终点。该线的起点。 points 参数指定终结点数组。 前两行指定第一行。 每个附加点指定其起点是上一行的终结点的线段的终结点。
