Does the compiler continue to evaluate the expression, where should everything be true if the first is false?

Question

I am sure that this question has probably already been answered, so I apologize, but I could not find the correct search conditions to find the answer.

Given the following code example, is it executing db.GetRecords().Any()?

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

Answer 1

No. As well &&, the short circuit rating is|| evaluated . This means that it returns false if it is false, but returns true if it is true and will not evaluate in any of these cases.a && baa || bab

- , & |.

Answer 2

. && ( , , - false).

|| , , true.

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