別にカンマ区切りじゃなくていいんやけど。

class Test
{
    static void Main (string [] args)
    {
        var s = "e0,106,aa,12";
        var regex = new System.Text.RegularExpressions.Regex ("\\b(\\d+)\\b");
        var matches = regex.Matches (s);
        var numbers = matches
            .OfType<System.Text.RegularExpressions.Match> ()
            .Select (match => Convert.ToInt32 (match.Groups [1].Value))
            .ToArray ();
        foreach (var number in numbers)
            Console.WriteLine ("{0}:{1}", number, number.GetType ());
    }
}
