Is Int32.ToString() culture-specific?

Question

I\'m running a beta version of ReSharper, and it\'s giving me warnings for the following code:

int id;
// ...
DoSomethingWith(id.ToString());

Answer 1

Because integers can be be as high as 2,147,483,647.

In some countries, they would use decimals or a space in place of the commas.
