Arithmetic operation resulted in an overflow. (Adding integers)

Question

I can\'t understand this error:

In this call to method SetVolume, Volume = 2055786000 and size = 93552000. Volume is an Integer pr

Answer 1

int.MaxValue = 2147483647
2055786000 + 93552000 = 2149338000 > int.MaxValue

So you cannot store this number into an integer. You could use Int64 type which has a maximum value of 9,223,372,036,854,775,807.
