I think this works:

   static void Main(string[] args)
    {
        String text = "One=1,Two=2,ThreeFour=34";

        Console.WriteLine(betweenStrings(text, "One=", ",")); // 1
        Console.WriteLine(betweenStrings(text, "Two=", ",")); // 2
        Console.WriteLine(betweenStrings(text, "ThreeFour=", "")); // 34

        Console.ReadKey();

    }

    public static String betweenStrings(String text, String start, String end)
    {
        int p1 = text.IndexOf(start) + start.Length;
        int p2 = text.IndexOf(end, p1);

        if (end == "") return (text.Substring(p1));
        else return text.Substring(p1, p2 - p1);                      
    }
