Convert string to decimal, keeping fractions

Question

I am trying to convert 1200.00 to decimal, but Decimal.Parse() removes .00. I\'ve tried some different methods, but it al

You can try calling this method in you program:

static double string_double(string s)
    {
        double temp = 0;
        double dtemp = 0;
        int b = 0;
        for (int i = 0; i < s.Length; i++)
        {
            if (s[i] == '.')
            {
                i++;
                while (i < s.Length)
                {
                    dtemp = (dtemp * 10) + (int)char.GetNumericValue(s[i]);
                    i++;
                    b++;
                }
                temp = temp + (dtemp * Math.Pow(10, -b));
                return temp;
            }
            else
            {
                temp = (temp * 10) + (int)char.GetNumericValue(s[i]);
            }
        }
        return -1; //if somehow failed
    }

Example:

string s = "12.3";
double d = string_double (s);        //d = 12.3
