What factors dictate throwing an exception if argument is null (eg if (a is null) throw new ArgumentNullException() ), as opposed to checking the argument if it is null beforehand.
I don't see why the exception should be thrown rather than checking for null in the first place? What benefit is there in the throw exception approach?
This is for C#/.NET
Thanks
