random value without creating object; int i = System::Random::Next(0,2) Why error?

error C2275: 'System::Random' : illegal use of this type as an expression
Iget this mistake if I try to build smt like this

int Number = System::Random::Next(0,4);

do I have to do it like this?

 Random^ rnd = (gcnew Random);
			 Number = rnd->Next(0,4);

thx
