you can't convert string 0.555 to double value 0.555

double d = double.Parse("0.555");

Always removes 0 from first place..

string s = "0.55555";
double d = Convert.ToDouble(s, System.Globalization.CultureInfo.InvariantCulture);
string s2 = d.ToString("#,#0.0");
Console.WriteLine(s2);

I are Troll

public static double StringToRoundedDouble(string s, int decimals)
{
    double result;
    if (double.TryParse(s, out result))
        result = Math.Round(result, decimals, MidpointRounding.AwayFromZero);
    return result;
}

double d =(StringToRoundedDouble("0.5555", 1);
