Is there any reasonable use for String.ToString?

Question

I just saw this

string response = GetResponse();
return response.ToString();

Is there any reasonable explanation for using the ToString() method?

Answer 1

No, there isn't. The only reason why it is available is, because it comes from Object. (And String inherits from Object)

Answer 2

That does nothing, from ILSpy:

public override string ToString()
{
    return this;
}

But maybe he wants to force a NullReferenceException, although that would not be best-practise.
