What your method should return if we give "0.30" value in parameter?
What is your requirement?

Or give some dummy values as input value and there expected results?

Solution 1

Your code is operating on the minutes portion of the HH:mm string incorrectly. If it was 30 mins, it should return 0.5. Your code for 30 mins returns 0.18.

C#

protected double ConvertTo100(string strTemp)
        {
            strTemp = strTemp.Replace(':', '.');

            double dblTemp;
            dblTemp = Convert.ToDouble(strTemp);

            double dblHH = Math.Floor(dblTemp);

            double dblMM = Math.Round(dblTemp - Math.Floor(dblTemp), 2) * 100 / 60; //i changed this line 

            double dboReturn;
            dboReturn = dblHH + dblMM;
            return dboReturn;
        }

as _Damian S_ said if we give "0.30" as input value it's result will be "0.5".
