Jun 11, 2011How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?

Jul 25, 2010Is it possible to extend primitive types such as System.String and System.Int32 (IE: integer) in .Net 4 and if so how?
To be more specific, I am aware of the concept of partial classes but this doesnt seem to be the answer. Also I find that System.String is not inheritable and Int32 is a structure.
