c# - How to convert percentage string to double?

Question

I have a string like "1.5%" and want to convert it to double value.

It can be done simple with following:

public static double FromPercentageString(this string value)
{
    return double.Parse(value.SubString(0, value.Length - 1)) / 100;
}

but I don't want to use this parsing approach.

Is any other approach with IFormatProvider or something like this?

Answer 1

It is culture sensitive, replace it like this:

  value = value.Replace(System.Globalization.CultureInfo.CurrentCulture.NumberFormat.PercentSymbol, "");

Then parse it.
