• 创建 FontFamily。

• 获取该字体系列的单元格升值。

• 将单元格的上升值绘制到屏幕作为文本。

public:
   void GetCellAscent_Example( PaintEventArgs^ e )
   {
      // Create a FontFamily object.
      FontFamily^ ascentFontFamily = gcnew FontFamily( "arial" );

      // Get the cell ascent of the font family in design units.
      int cellAscent = ascentFontFamily->GetCellAscent( FontStyle::Regular );

      // Draw the result as a string to the screen.
      e->Graphics->DrawString( String::Format( "ascentFontFamily.GetCellAscent() returns {0}.", cellAscent ),
            gcnew System::Drawing::Font( ascentFontFamily,16 ), Brushes::Black, PointF(0,0) );
   }

public void GetCellAscent_Example(PaintEventArgs e)
{
    // Create a FontFamily object.
    FontFamily ascentFontFamily = new FontFamily("arial");
             
    // Get the cell ascent of the font family in design units.
    int cellAscent = ascentFontFamily.GetCellAscent(FontStyle.Regular);
             
    // Draw the result as a string to the screen.
    e.Graphics.DrawString(
        "ascentFontFamily.GetCellAscent() returns " + cellAscent.ToString() + ".",
        new Font(ascentFontFamily, 16),
        Brushes.Black,
        new PointF(0, 0));
}

Public Sub GetCellAscent_Example(ByVal e As PaintEventArgs)

    ' Create a FontFamily object.
    Dim ascentFontFamily As New FontFamily("arial")

    ' Get the cell ascent of the font family in design units.
    Dim cellAscent As Integer = _
    ascentFontFamily.GetCellAscent(FontStyle.Regular)

    ' Draw the result as a string to the screen.
    e.Graphics.DrawString("ascentFontFamily.GetCellAscent() returns " _
    & cellAscent.ToString() & ".", New Font(ascentFontFamily, 16), _
    Brushes.Black, New PointF(0, 0))
End Sub
