Whats the difference between if( null == this.somevariable ) and if( this.somevariable == null)

Question

Dumb question I get it..but what the difference between these two statements

if( null == this.someVariable)
{
 //do something
}

and 

if( this.someVariable == null )
{
//do something.
}

Answer 1

They are the same from a code point of view. Some people prefer the first style, because if you then make a mistake and type = instead of == you'll get an error

Answer 2

There's absolutely no difference at all. Except maybe which looks better to you.

It's a relic from the C\C++ world where:

if(null = someVariable)
{
}

Would give an error. But:

if(someVariable = null)
{
}

Would not.
