[Solved] Why use != null in if statements?

Question

if expressions have to be boolean. Say I have a string:

string test = null;

if (test) won’t compile because test is not a bool. It just returns the string reference. So, to check for null, you actually have to check for null:

if (test != null) is an expression that does return a bool, and so compiles, and is a standard way of checking for null.
