Font Constructor (String, Single, FontStyle, GraphicsUnit)

Initializes a new Font using a specified size, style, and unit.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public Font(
	string familyName,
	float emSize,
	FontStyle style,
	GraphicsUnit unit


Type: System.String
A string representation of the FontFamily for the new Font.
Type: System.Single
The em-size of the new font in the units specified by the unit parameter.
Type: System.Drawing.FontStyle
The FontStyle of the new font.
Type: System.Drawing.GraphicsUnit
The GraphicsUnit of the new font.


emSize is less than or equal to 0, evaluates to infinity or is not a valid number.

Windows Forms applications support TrueType fonts and have limited support for OpenType fonts. If the familyName parameter specifies a font that is not installed on the machine running the application or is not supported, Microsoft Sans Serif will be substituted.

The following code example demonstrates how to use the Font constructor. This example is designed to be used with Windows Forms. To run this example, paste this code into a form that contains a button named Button2, and associate the Button2_Click method with the Click event of the button.

private void Button2_Click(System.Object sender, System.EventArgs e)

    Button2.Font = new Font(FontFamily.GenericMonospace, 12.0F, 
        FontStyle.Italic, GraphicsUnit.Pixel);
