Difference between long and int in C#?

Question

What is the actual difference between a long and an int in C#? I understand that in C/C++ long would be 64bit on some 64bit platforms(depending on OS o

Answer 1

int in C#=> System.Int32=>from -2,147,483,648 to 2,147,483,647.

long in C#=> System.Int64 =>from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807

If your long data exceeds the range of int, and you use Convert.ToInt32 then it will throw OverflowException, if you use explicit cast then the result would be unexpected.
