Question

I have an array of bytes (any length), and I want to encode this array into string using my own base encoder. In .NET is standard Base64 encoder, but w

Here is a copy from my blog which I hope helps how (and why) I convert to Base62

I am currently working on my own url shortener: konv.es. In order to create the shortest possible character hash of the url, I use the GetHashCode() method of the string, then convert the resulting number to base 62 ([0-9a-zA-Z]). The most elegant solution that I have found thus far to make the convertion (which is also a handy-dandy example of a yield return) is:

public static IEnumerable ToBase62(int number)
    {
        do
        {
            yield return "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"[number % 62];
            number /= 62;

        } while (number > 0);
    }
