Color.ToKnownColor Method
Gets the KnownColor value of this Color structure.
[Visual Basic] Public Function ToKnownColor() As KnownColor [C#] public KnownColor ToKnownColor(); [C++] public: KnownColor ToKnownColor(); [JScript] public function ToKnownColor() : KnownColor;
Return Value
An element of the KnownColor enumeration, if the Color structure is created from a pre-defined color by using either the FromName method or the FromKnownColor method; otherwise, zero.
Remarks
A pre-defined 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, the ToKnownColor method returns zero, even if the ARGB value matches the ARGB value of a pre-defined color. The ToKnownColor method also returns zero when it is applied to a Color structure that is created by using the FromName method with an invalid string name.
