This question already has an answer here:

What is the difference between String and string in C#? 59 answers

What is 'long?' data type? 6 answers

There is no difference in the compiled code. They are aliases for the same thing.

here is something more strange:

Convert.ToInt64(27.5) = 28

(int64)27.5 = 27

I think, the difference is at cast and convert level rather than at datatype level.
