Color.FromName Method

Creates a Color structure from the specified name of a predefined color.

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

public static Color FromName(
	string name
)

Parameters

name
Type: System.String

A string that is the name of a predefined color. Valid names are the same as the names of the elements of the KnownColor enumeration.

Return Value

Type: System.Drawing.Color
The Color that this method creates.

A predefined color is also called a known color and is represented by an element of the KnownColor enumeration. If the name parameter is not the valid name of a predefined color, the FromName method creates a Color structure that has an ARGB value of 0 (that is, all ARGB components are 0).

The following code example demonstrates the A, R, G, B, and FromName members of a Color, and the Implicit member.

This example is designed to be used with a Windows Form. Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form's Paint event-handling method, passing e as PaintEventArgs.

private void ShowPropertiesOfSlateBlue(PaintEventArgs e)
{
    Color slateBlue = Color.FromName("SlateBlue");
    byte g = slateBlue.G;
    byte b = slateBlue.B;
    byte r = slateBlue.R;
    byte a = slateBlue.A;
    string text = String.Format("Slate Blue has these ARGB values: Alpha:{0}, " +
        "red:{1}, green: {2}, blue {3}", new object[]{a, r, g, b});
    e.Graphics.DrawString(text, 
        new Font(this.Font, FontStyle.Italic), 
        new SolidBrush(slateBlue), 
        new RectangleF(new PointF(0.0F, 0.0F), this.Size));
}
