Hello freinds,
Recently i was interviewes in accenture and i was asked what the difference between tostring and convertostring. I think tostring checks for spaces and convertostring does not

[khadakbist]

Its not spaces its nulls.
convert.tostring handles nulls while simple tostring() function does not handle null.
