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。 程序代碼會建立 Pen，並將其設定為在行開頭繪製箭頭錨點上限：

public:
   void SetLineCap_Example( PaintEventArgs^ e )
   {
      
      // Create a Pen object with a dash pattern.
      Pen^ capPen = gcnew Pen( Color::Black,5.0f );
      capPen->DashStyle = DashStyle::Dash;
      
      // Set the start and end caps for capPen.
      capPen->SetLineCap( LineCap::ArrowAnchor, LineCap::Flat, DashCap::Flat );
      
      // Draw a line with capPen.
      e->Graphics->DrawLine( capPen, 10, 10, 200, 10 );
   }

public void SetLineCap_Example(PaintEventArgs e)
{
             
    // Create a Pen object with a dash pattern.
    Pen capPen = new Pen(Color.Black, 5);
    capPen.DashStyle = DashStyle.Dash;
             
    // Set the start and end caps for capPen.
    capPen.SetLineCap(LineCap.ArrowAnchor, LineCap.Flat, DashCap.Flat);
             
    // Draw a line with capPen.
    e.Graphics.DrawLine(capPen, 10, 10, 200, 10);
}

Public Sub SetLineCap_Example(ByVal e As PaintEventArgs)

    ' Create a Pen object with a dash pattern.
    Dim capPen As New Pen(Color.Black, 5)
    capPen.DashStyle = DashStyle.Dash

    ' Set the start and end caps for capPen.
    capPen.SetLineCap(LineCap.ArrowAnchor, LineCap.Flat, DashCap.Flat)

    ' Draw a line with capPen.
    e.Graphics.DrawLine(capPen, 10, 10, 200, 10)
End Sub
