Color.ToKnownColor Method

Gets the KnownColor value of this Color structure.

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

public KnownColor ToKnownColor()

Return Value

Type: System.Drawing.KnownColor
An element of the KnownColor enumeration, if the Color is created from a predefined color by using either the FromName method or the FromKnownColor method; otherwise, 0.

A predefined color is also called a known color and is represented by an element of the KnownColor enumeration. When the ToKnownColor method is applied to a Color structure that is created by using the FromArgb method, ToKnownColor returns 0, even if the ARGB value matches the ARGB value of a predefined color. ToKnownColor also returns 0 when it is applied to a Color structure that is created by using the FromName method with a string name that is not valid.
