The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a FontFamily.

  • Gets the em square height for that font family.

  • Draws the value of the em height to the screen as text.

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

public void GetEmHeight_Example(PaintEventArgs e)
{
    // Create a FontFamily object.
    FontFamily emFontFamily = new FontFamily("arial");

    // Get the em height of the font family in design units.
    int emHeight = emFontFamily.GetEmHeight(FontStyle.Regular);

    // Draw the result as a string to the screen.
    e.get_Graphics().DrawString("emFontFamily.GetEmHeight() returns "  
        + System.Convert.ToString(emHeight) + ".",  
        new Font(emFontFamily, 16), Brushes.get_Black(), new PointF(0, 0));
} //GetEmHeight_Example
