In c# difference between (user==null) and (null==user) [duplicate]

Answer 1

No, no difference.

You use the former because sometimes, in some languages, accidental assignment can result in 'true' (JavaScript, for example).

So you prefer to write the constant on the left, so that it's a compile time (if you have it, JavaScript obviously doesn't) error, or at best, a runtime error, instead of just a bug.

Answer 2

if(user==null) is easier to read

Answer 3

They achieve the same. Personally I have never seen null == user in any of my projects, but if I should render a guess, I'd say it's connected to how you read your every day language. If you are from Europe, odds are you read from left to right, but some languages read from right to left, that may be where it comes from.

Answer 4

user == null is human speak.

null == user is Yoda speak.

To the compiler they are the same, so pick the one you are most comfortable with.
