How to get a string between 2 specific characters in C#

Having a hard time with Regex.

I have this string:

I need to replace this whole number "11.000000" with another number.

How do I identify this string by saying:

Give me the string right before "%" until you reach the first blank space (" ")?

Try this:

string pattern = @"^Fixed Breakeven with (\d+(\.\d+)?)% Fees$";
string input = "Fixed Breakeven with 11.0000000% Fees";

var match = Regex.Match(input, pattern);
string output = string.Empty;

if (match != null)
{
    output = match.Groups[1].Value;
}

Produces 11.0000000.

You can try this also, using regex. This is generic method to fetch decimal from string. It will work for all cases.

public static bool ExtractDecimalFromString(string inputString, out Decimal decimalValue)
    {
        Regex regex = new Regex(@"^\D*?((-?(\d+(\.\d+)?))|(-?\.\d+)).*");
        Match match = regex.Match(inputString);
        decimalValue =  match.Success ? Convert.ToDecimal(match.Groups[1].Value) : 0;
        return match.Success;
    }

You can use LINQ:

var myString = "Fixed Breakeven with 11.0000000% Fees";
var number = myString.Split('%').First().Split(' ').Last();
