Answer / xiaof

A const field can only be initialized at the declaration of
the field. A readonly field can be initialized either at
the declaration or in a constructor. Therefore, readonly
fields can have different values depending on the
constructor used. Also, while a const field is a compile-
time constant, the readonly field can be used for runtime
constants as in the following example:
public static readonly uint l1 = (uint) DateTime.Now.Ticks;
