how do i change background colors based on current one by using a switch

Question

so i am trying to change the background color based on the current color by using a switch however iam getting an error.

switch (BtnColor.BackgroundColor)
            {
                case Color.Red:
                    BtnColor.BackgroundColor = Color.White;
                    break;
                case Color.White:
                    BtnColor.BackgroundColor = Color.Blue;
                    break;
                default:
                    BtnColor.BackgroundColor = Color.Red;
                    break;
            }

i am getting the following error on: case Color.White: and case Color.Red:

A constant value is expected

Answer 1

Colors are not constants, and that's what you're supposed to use when using Switch statements.

Predefined Colors are Static Properties of the Color class, so that can't be used.

In this case you can use if/then/else statements to achieve the same exact thing.
