String parsing, extracting numbers and letters

Question

What\'s the easiest way to parse a string and extract a number and a letter? I have string that can be in the following format (number|letter or letter|number), i.e \"10A\",

Answer 1

Here is how I would approach this. You can step through this and put gc1["letter"], gc1["number"], gc2["letter"], and gc2["number"] in the watch window to see that it worked (step just past the last line of code here, of course).

The regular epxression will take either pattern requiring one or more letter and number in each case.

        Regex pattern = new Regex("^(?[a-zA-Z]+)(?[0-9]+)|(?[0-9]+)(?[a-zA-Z]+)$");
        string s1 = "12A";
        string s2 = "B45";
        Match m1 = pattern.Match(s1);
        Match m2 = pattern.Match(s2);
        GroupCollection gc1 = m1.Groups;
        GroupCollection gc2 = m2.Groups;
