title: Is there a difference between private const and private readonly variables in C#?
body: <p>Is there a difference between having a <code>private const</code> variable or a <code>private static readonly</code> variable in C# (other than having to assign the <code>const</code> a compile-time expression)?</p>
  
  <p>Since they are both private, there is no linking with other libraries. So would it make any difference? Can it make a performance difference for example? Interned strings? Anything similar?</p>
