Font Constructor (String, Single)

Initializes a new Font using a specified size.

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

public Font(
	string familyName,
	float emSize
)

Parameters

familyName
Type: System.String

A string representation of the FontFamily for the new Font.

emSize
Type: System.Single

The em-size, in points, of the new font.

ExceptionCondition
ArgumentException

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

The resulting font has its Style property set to FontStyle.Regular and its Unit property set to GraphicsUnit.Point. 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 a Windows Form and requires a PaintEventArgs e, which is a parameter of the Paint event.

private void ConstructFontWithString(PaintEventArgs e)
{
    Font font1 = new Font("Arial", 20);
    e.Graphics.DrawString("Arial Font", font1, Brushes.Red, new PointF(10, 10));
}
