&&= in C#? (boolean expression) [duplicate]

Question

Why are there no ||= or &&= operators?

By pure accident I found out today that

 a &= GetBool();

is NOT the same as

 a = a && GetBool();

I must have misunderstood that for years. In the first Example, "GetBool()" is executed even if "a" is false. In the second, it isn't.

Is there anything to achieve something like "&&=" in C#?

Well, you can write

a = a && getBool();

instead... I can't think of many situations where I'd actually want to do anything different, to be honest. Even the above is pretty rare, IME.

There's no compound assignment operator defined for &&, || or ?? (which are the obvious "short-circuiting" operators). See section 7.17 of the C# 4 spec for the full list of compound assignment operators, and section 7.17.2 for more details about what exactly compound assignment does.
