c# - How to get color from string

Get Color from String
The String represents text as a sequence of UTF-16 code units. The String is a sequential collection of characters that is used to represent text. The String is a sequential collection of System.Char objects.

The following .net c# tutorial code demonstrates how we can get a Color instance from a String object. So, in this .net c# tutorial code we will convert a String instance that contains a color name into a Color object. The Color represents an ARGB (alpha, red, green, blue) color.

The Color FromName() method creates a Color structure from the specified name of a predefined color. The Color FromName(string name) has a required parameter named ‘name’. The Color FromName(string name) method's name parameter is a String that is the name of a predefined color. The valid names are the same as the names of the elements of the KnownColor enumeration.

The Color FromName() method returns a Color that this method creates. If the name parameter is not the valid name of a specified color then the method creates a Color structure that has an ARGB value of 0. All ARGB components are 0. So, using this Color FromName(String) method the .net c# developers can get a Color object from a String instance.
