範例

下列方法示範設定 DashCap、 DashPattern和 SmoothingMode 屬性的效果。 下列圖例顯示範例的輸出。

此範例的設計目的是要與 Windows Forms 搭配使用。 將程式代碼貼到表單中，並在處理表單的事件時呼叫 ShowPensAndSmoothingMode 方法，並e傳遞為 PaintEventArgs。Paint

private:
   void ShowPensAndSmoothingMode( PaintEventArgs^ e )
   {
      // Set the SmoothingMode property to smooth the line.
      e->Graphics->SmoothingMode = System::Drawing::Drawing2D::SmoothingMode::AntiAlias;

      // Create a new Pen object.
      Pen^ greenPen = gcnew Pen( Color::Green );

      // Set the width to 6.
      greenPen->Width = 6.0F;

      // Set the DashCap to round.
      greenPen->DashCap = System::Drawing::Drawing2D::DashCap::Round;

      // Create a custom dash pattern.
      array<Single>^temp0 = {4.0F,2.0F,1.0F,3.0F};
      greenPen->DashPattern = temp0;

      // Draw a line.
      e->Graphics->DrawLine( greenPen, 20.0F, 20.0F, 100.0F, 240.0F );

      // Change the SmoothingMode to none.
      e->Graphics->SmoothingMode = System::Drawing::Drawing2D::SmoothingMode::None;

      // Draw another line.
      e->Graphics->DrawLine( greenPen, 100.0F, 240.0F, 160.0F, 20.0F );

      // Dispose of the custom pen.
      delete greenPen;
   }

    // Create a new Pen object.
    Pen greenPen = new Pen(Color.Green);

    // Set the width to 6.
    greenPen.Width = 6.0F;

    // Set the DashCap to round.
    greenPen.DashCap = System.Drawing.Drawing2D.DashCap.Round;

    // Create a custom dash pattern.
    greenPen.DashPattern = new float[]{4.0F, 2.0F, 1.0F, 3.0F};

備註

平滑模式會指定填滿區域的線條、曲線和邊緣是否使用平滑化 (也稱為反鋸齒) 。 其中一個例外狀況是路徑漸層筆刷不會遵守平滑模式。 不論 屬性為何，使用 PathGradientBrush 填滿的區域會以相同方式呈現 (別名) SmoothingMode 。
