Do short-circuiting operators || and && exist for nullable booleans? The RuntimeBinder sometimes thinks so

Question

I read the C# Language Specification on the Conditional logical operators || and &&, also known as the short-circuiting logical operat

Answer 1

The Nullable type does not define Conditional logical operators || and &&. I suggest you following code:

bool a = true;
bool? b = null;

bool? xxxxOR = (b.HasValue == true) ? (b.Value || a) : a;
bool? xxxxAND = (b.HasValue == true) ? (b.Value && a) : false;
