Answer 1

Similar to Lukes answer, with a lot more code and room for improvement. BUT it deals with negatives Hours ("-30:15") aswell, so maybe it can help someone.

public static double GetTotalHours(String s)
    {
        bool isNegative = false;
        if (s.StartsWith("-"))
            isNegative = true;

        String[] splitted = s.Split(':');
        int hours = GetNumbersAsInt(splitted[0]);
        int minutes = GetNumbersAsInt(splitted[1]);

        if (isNegative)
        {
            hours = hours * (-1);
            minutes = minutes * (-1);
        }
        TimeSpan t = new TimeSpan(hours, minutes, 0);
        return t.TotalHours;
    }

public static int GetNumbersAsInt(String input)
        {
            String output = String.Empty;
            Char[] chars = input.ToCharArray(0, input.Length);
            for (int i = 0; i < chars.Length; i++)
            {
                if (Char.IsNumber(chars[i]) == true)
                    output = output + chars[i];
            }
            return int.Parse(output);
        }

usage

double result = GetTotalHours("30:15");
double result2 = GetTotalHours("-30:15");
