The expression being assigned to 'variable' must be constant
A const variable cannot take as its value a variable that is not const.
The following sample generates CS0133:
namespace x { public class a { public static void Main() { } } public class b : a { public const int i = c; // CS0133, c is not const public static int c = i; // try the following line to resolve CS0133 // public const int c = 6; } }
