If you use obj.ToString() and obj is null then here you will get an NullReferenceException. While if you are using Convert.ToString(obj) then it will not throw an exception if obj is null.

ToString can not hold the Null value. Convert.ToString can hold the Null value

if you invoke ToString() on null string it will throw NullReferenceException and Convert.ToString() does not throw NullReferenceException,instead you get empty string

It is huge. ToString() is method inherited from Object.
Convert.ToString is a method from IConvertible

Convert simply cast your object into IConvertible and calls appropriate method.
