Is there a difference between having a private const variable or a private static readonly variable in C# (other than having to assign the co

Answer 1

Readonly fields can be initialized either at the declaration or in a constructor of a class. Therefore readonly fields can have different values depending on the constructor used.

A readonly member can also be used for runtime constants as in the following example:

public static readonly uint currentTicks = (uint)DateTime.Now.Ticks;

Readonly fields are not implicitly static, and therefore the static keyword can (must) be applied to a readonly field explicitly if required. This is not allowed for const fields, which are implicitly static.

Readonly members can hold complex objects by using the new keyword at initialization.
