繪製 GraphicsPath。

public:
 void DrawPath(System::Drawing::Pen ^ pen, System::Drawing::Drawing2D::GraphicsPath ^ path);

public void DrawPath (System.Drawing.Pen pen, System.Drawing.Drawing2D.GraphicsPath path);

member this.DrawPath : System.Drawing.Pen * System.Drawing.Drawing2D.GraphicsPath -> unit

Public Sub DrawPath (pen As Pen, path As GraphicsPath)

參數

pen

Pen

Pen，決定路徑的色彩、寬度和樣式。

path

GraphicsPath

要繪製的 GraphicsPath。

例外狀況

ArgumentNullException

pen null。

-或-

path null。

範例

下列程式代碼範例是專為搭配 Windows Forms 使用而設計，而且需要 PaintEventArgse，這是 Paint 事件處理程式的參數。 程式代碼會執行下列動作：

• 建立圖形路徑物件，並將省略號加入其中。

• 建立黑色畫筆。

• 繪製畫面的圖形路徑。

public:
   void DrawPathEllipse( PaintEventArgs^ e )
   {
      // Create graphics path object and add ellipse.
      GraphicsPath^ graphPath = gcnew GraphicsPath;
      graphPath->AddEllipse( 0, 0, 200, 100 );

      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Draw graphics path to screen.
      e->Graphics->DrawPath( blackPen, graphPath );
   }

public void DrawPathEllipse(PaintEventArgs e)
{
             
    // Create graphics path object and add ellipse.
    GraphicsPath graphPath = new GraphicsPath();
    graphPath.AddEllipse(0, 0, 200, 100);
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Draw graphics path to screen.
    e.Graphics.DrawPath(blackPen, graphPath);
}

Public Sub DrawPathEllipse(ByVal e As PaintEventArgs)

    ' Create graphics path object and add ellipse.
    Dim graphPath As New GraphicsPath
    graphPath.AddEllipse(0, 0, 200, 100)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Draw graphics path to screen.
    e.Graphics.DrawPath(blackPen, graphPath)
End Sub

備註

在繪製圖形內容之前，圖形內容中的目前轉換會套用至 GraphicsPath。
