To tell you more Convert internally uses toString. In convert first there is a check for null, if there is null then string.empty is returned, else normal toString method is called

String.Convert:
convert the string from one to another.
String.toString:
divide the string into sub string

String.Convert will not allow null value
String.ToString will allow null value...

String.Convert:

See the example.

Line 1 :String str1 = null;
Line 2: Console.WriteLine("->" + Convert.ToString(str1) + "<-";
Line 3: Console.WriteLine("->" + str1.ToString() + "<-");

In the above example,
Line 2 will display the result("-><-"), because Convert.ToString() handle NULL.
Line 3 will throw NullReferenceException because .ToString() does not handle NULL.
