In reply to your comment " if i start converting them it will take time... and don't want to do that.". Everything takes time, how else do you think computers work? In reality it is a short compute loop that will take a minute to write and a few microseconds to run, much less time than it takes to post this comment.

Solution 1

Well if you consider the number and type of characters that are in the key it's unlikely that you can do a straight conversion to an integer. You could, however write a conversion that reduces it to an integer; for example take the binary value of each character in turn and add them together to reduce it to a 32 or 64 bit value. Remember, however that such a value is not likely to be unique.

Solution 2

If you just need to generate a derivative integer from a string, why not call the GetHashcode() method which returns an integer?

Solution 3

This looks like Base-64 encoding to me. Google Base64 and see what you get.
