AddRectangles(Rectangle[])

Source:

GraphicsPath.cs

向此路径添加一系列矩形。

public:
 void AddRectangles(cli::array <System::Drawing::Rectangle> ^ rects);

public void AddRectangles (System.Drawing.Rectangle[] rects);

member this.AddRectangles : System.Drawing.Rectangle[] -> unit

示例

下面的代码示例旨在与 Windows 窗体 一起使用，它需要 PaintEventArgse事件OnPaint对象。 此代码执行以下操作：

• 创建路径。

• 创建矩形数组，并将矩形添加到路径。

• 绘制屏幕的路径。

private:
   void AddRectanglesExample( PaintEventArgs^ e )
   {
      // Adds a pattern of rectangles to a GraphicsPath object.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      array<Rectangle>^ pathRects = {Rectangle(20,20,100,200),Rectangle(40,40,120,220),Rectangle(60,60,240,140)};
      myPath->AddRectangles( pathRects );

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

private void AddRectanglesExample(PaintEventArgs e)
{
             
    // Adds a pattern of rectangles to a GraphicsPath object.
    GraphicsPath myPath = new GraphicsPath();
    Rectangle[] pathRects =
             {
                 new Rectangle(20,20,100,200),
                 new Rectangle(40,40,120,220),
                 new Rectangle(60,60,240,140)
             };
    myPath.AddRectangles(pathRects);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Public Sub AddRectanglesExample(ByVal e As PaintEventArgs)

    ' Adds a pattern of rectangles to a GraphicsPath object.
    Dim myPath As New GraphicsPath
    Dim pathRects As Rectangle() = {New Rectangle(20, 20, 100, 200), _
    New Rectangle(40, 40, 120, 220), New Rectangle(60, 60, 240, 140)}
    myPath.AddRectangles(pathRects)

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

AddRectangles(RectangleF[])

public:
 void AddRectangles(cli::array <System::Drawing::RectangleF> ^ rects);

public void AddRectangles (System.Drawing.RectangleF[] rects);

member this.AddRectangles : System.Drawing.RectangleF[] -> unit

Public Sub AddRectangles (rects As RectangleF())

参数

rects

RectangleF[]

一个 RectangleF 结构的数组，它表示要添加的矩形。
