I hate to contradict what has already been suggested but you don't
want to use static or readonly, you want to use the 'const' keyword.

'const' has an advantage over static readonly fields as the values are
calculated at compile time. eg.

   class MyClass 
   {
      public int x;
      public static readonly int c2 = 5;
   }

   public static void Main() 
   {
      Console.WriteLine("c1 = {0}, c2 = {1}", MyClass.c1, MyClass.c2
Console.WriteLine("c1*4 = {0}, c2*4 = {1}", MyClass.c1*4, MyClass.c2*4     
);

In the second WriteLine the compiler will pre calculate the value 20,
for c2 it will perform the calculation on each execution.

A couple of points 'const' fields are automatically static and
read-only.

'readonly' fields aren't always.
