Question

I’m sure this question has probably been answered before, so I apologize, but I wasn’t able to find the proper search terms to find the answer.

Given the following code example, does db.GetRecords().Any() get executed?

string s = "Z";
bool x = s.IndexOfAny(new[] { 'A', 'B' }) > 0 &&
         db.GetRecords().Any();

Answer 1

No. Both && and || are evaluated by short-circuit evaluation. This means that a && b returns false if a is false and a || b returns true if a is true and it will not evaluate b in either of these cases.

If for some reason you do not want short-circuit evaluation you can use the bitwise operators & and |.
