'const string' vs. 'static readonly string' in C#

Question

In C#, what\'s the difference between

static readonly string MyStr;

and

const string MyStr;

?

Answer 1

Here is a good breakdown of the pros and cons:

So, it appears that constants should be used when it is very unlikely that the value will ever change, or if no external apps/libs will be using the constant. Static readonly fields should be used when run-time calculation is required, or if external consumers are a factor.
