Finding the string length of a integer in .NET

Question

In .NET what is the best way to find the length of an integer in characters if it was represented as a string?

e.g.

1 = 1 character
10 = 2 characters

Answer 1

You could use something like this:

        int integer = 100;

        int charachtersCount = 0;
        while (integer > 0)
        {
            integer = integer/10;
            charachtersCount++;
        }

But do you really need to optimize this? I would actually prefer using string (looks much better):

integer.ToString().Length
