public:
 System::Drawing::PointF GetLastPoint();

public System.Drawing.PointF GetLastPoint ();

member this.GetLastPoint : unit -> System.Drawing.PointF

Public Function GetLastPoint () As PointF

Mengembalikan

PointF

PointF yang mewakili titik terakhir dalam GraphicsPathini.

Contoh

Contoh kode berikut dirancang untuk digunakan dengan Windows Forms, dan memerlukan PaintEventArgse, objek peristiwa OnPaint. Kode membuat jalur, menambahkan baris ke jalur, lalu mendapatkan titik terakhir di jalur.

private:
   void GetLastPointExample( PaintEventArgs^ /*e*/ )
   {
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddLine( 20, 20, 100, 20 );
      PointF lastPoint = myPath->GetLastPoint();
      if ( lastPoint.IsEmpty == false )
      {
         String^ lastPointXString = lastPoint.X.ToString();
         String^ lastPointYString = lastPoint.Y.ToString();
         MessageBox::Show( String::Concat( lastPointXString, ", ", lastPointYString ) );
      }
      else
            MessageBox::Show( "lastPoint is empty" );
   }

private void GetLastPointExample(PaintEventArgs e)
{
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddLine(20, 20, 100, 20);
    PointF lastPoint = myPath.GetLastPoint();
    if(lastPoint.IsEmpty == false)
    {
        string lastPointXString = lastPoint.X.ToString();
        string lastPointYString = lastPoint.Y.ToString();
        MessageBox.Show(lastPointXString + ", " + lastPointYString);
    }
    else
    {
        MessageBox.Show("lastPoint is empty");
    }
}

Public Sub GetLastPointExample(ByVal e As PaintEventArgs)
    Dim myPath As New GraphicsPath
    myPath.AddLine(20, 20, 100, 20)
    Dim lastPoint As PointF = myPath.GetLastPoint()
    If lastPoint.IsEmpty = False Then
        Dim lastPointXString As String = lastPoint.X.ToString()
        Dim lastPointYString As String = lastPoint.Y.ToString()
        MessageBox.Show((lastPointXString + ", " + lastPointYString))
    Else
        MessageBox.Show("lastPoint is empty")
    End If
End Sub
