Compiler Error CS0133

The expression being assigned to 'variable' must be constant

A const variable cannot take as its value an expression that is not constant. For more information, see Constants (C# Programming Guide).

The following sample generates CS0133:

// CS0133.cs
public class MyClass
{
   public const int i = c;   // CS0133, c is not constant
   public static int c = i;
   // try the following line instead
   // public const int i = 6;

   public static void Main()
   {
   }
}
