Conditional Statements difference

Question

Is there any difference between below two statements

if (null != obj)

and

if (obj != null)

If both treate

Answer 1

No, there is not. It's exactly the same.

The style null == obj is sometimes just used to prevent the common typo obj = null to not accidently assign null to a variable, but with != there's absolutely no reason to do so.

In .NET it won't actually compile for the typo obj = null.
So the compiler prevents you from accidently doing it.

The Yoda condition comes originally from other languages, where this compiler feature is missing.
