Here you go:

using System;
using System.Text.RegularExpressions;

namespace RegVer {
    class Prog {
        static void Main() {
            var verstring = "ver:1:9.5";
            var dotVerString = verstring.Replace(':','.');
            Console.WriteLine(Regex.Match(dotVerString, @"ver\.([\d\.]+)").Groups[1].Value);
        }
    }
}

Or if you want array with each version digit.

using System;
using System.Text.RegularExpressions;

namespace RegVer {
    class Prog {
        static void Main() {
            var verstring = "ver:1:9.5";
            var VerABC = Regex.Matches(verstring, @"\d");
            Console.WriteLine("a = " + VerABC[0] + "\n" +
                              "b = " + VerABC[1] + "\n" +
                              "c = " + VerABC[2]);
        }
    }
}
