Regular expression for parsing mailing addresses

I need to split a street address that will have one of two forms.

12B Main Road
Main Road 12B

(all parts are optional)

I need to split into street name(Main), street type(Road, already have a list of possible street types), street number (12) and the street number suffix(B).

Any advice?

Will be doing this in C#.

Answer 1

considering that I don’t know all of the details(how you can expect roads to be formatted), this question is very hard to answer, but I’ll do what I can.

for your 2 specific examples, you can have

@"([\d|A-Z]*) ([A-Z|a-z| ]*) ([A-Z|a-z]*)"

will match the order of your first answer

@"([A-Z|a-z| ]*) ([A-Z|a-z]*) ([\d|A-Z]*)"

will match your second answer.

example:

        Regex regex = new Regex(@"([\d|A-Z]*) ([A-Z|a-z| ]*) ([A-Z|a-z]*)");

        foreach (Group g in regex.Match("12B Main Road").Groups)
        {

            Console.WriteLine(g.Value);
        }

output from that program looks something like the following

12B Main Road
12B
Main
Road
