Color.AliceBlue
<source lang="csharp"> //ColorGuide.cs /*
This Program will generate all the colors that are supported in C# according to the Name.... I expected from you a better version of this program If you can , then inform me how you made it e.g. you make a dll file where the whole color array is stored then your coding lines will decrease. I tried that way but the trial was in vane....
