Hi

Carrying on from this question What is the difference between Convert and Parse?

Here are two lines of code.

Convert.ToString(myObject);
myObject.ToString();

My question is what is the difference and which would be best to use?

Thank you in advance.

The basic difference between them is Convert function handles NULLs while i.ToString() does not. It will throw a NULL reference exception error. So, as good coding practice using Convert is always safe.

Just to clarify - Convert.ToString(null) would return null? – Ash Burlaczenko Aug 17 '10 at 08:27
@Ash, yes it returns null although one might reasonably expect it to return the empty string. – Paul Ruane Aug 17 '10 at 08:32

myObject.ToString() could throw a NullReferenceException, where Convert.ToString will never do that.
