例外狀況

ArgumentException

該 Width 性質設定在一個不變的 Pen上，例如類別回傳 Pens 的 。

範例

以下程式碼範例展示了將 和 LineJoin 屬性設定Width在 Pen。

此範例設計用於 Windows 表單。 將程式碼貼到表單中，處理表單Paint事件時呼叫該ShowLineJoin方法，傳遞e為 PaintEventArgs。

private:
   void ShowLineJoin( PaintEventArgs^ e )
   {
      // Create a new pen.
      Pen^ skyBluePen = gcnew Pen( Brushes::DeepSkyBlue );

      // Set the pen's width.
      skyBluePen->Width = 8.0F;

      // Set the LineJoin property.
      skyBluePen->LineJoin = System::Drawing::Drawing2D::LineJoin::Bevel;

      // Draw a rectangle.
      e->Graphics->DrawRectangle( skyBluePen, Rectangle(40,40,150,200) );

      //Dispose of the pen.
      delete skyBluePen;
   }

private void ShowLineJoin(PaintEventArgs e)
{

    // Create a new pen.
    Pen skyBluePen = new Pen(Brushes.DeepSkyBlue);

    // Set the pen's width.
    skyBluePen.Width = 8.0F;

    // Set the LineJoin property.
    skyBluePen.LineJoin = System.Drawing.Drawing2D.LineJoin.Bevel;

    // Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, 
        new Rectangle(40, 40, 150, 200));

    //Dispose of the pen.
    skyBluePen.Dispose();
}

Private Sub ShowLineJoin(ByVal e As PaintEventArgs)

    ' Create a new pen.
    Dim skyBluePen As New Pen(Brushes.DeepSkyBlue)

    ' Set the pen's width.
    skyBluePen.Width = 8.0F

    ' Set the LineJoin property.
    skyBluePen.LineJoin = Drawing2D.LineJoin.Bevel

    ' Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, _
        New Rectangle(40, 40, 150, 200))

    'Dispose of the pen.
    skyBluePen.Dispose()

End Sub

備註

你可以利用物件的PageUnit特性來取得其度量Graphics單位。 度量單位通常是像素。 A Width 為 0 時，抽獎結果 Pen 就像 Width 1 一樣。
