Solution 1

Use string.LastIndexOf and string.IndexOf to get the two brackets.
You can then use string.SubString to get the values.

I think you may be writing the value of quantity and value of price in the above format like image 45.5(35.45), in which case the following Regex pattern can be used to retrieve the quantity and price part.

C#

string qtyPrice = @"image  45.5(35.45) ";
    Match match = Regex.Match(qtyPrice,@"\s+([\d.]+)\s*\(\s*([\d.]+)\s*\)",
         RegexOptions.CultureInvariant | RegexOptions.IgnoreCase);
    double quantity;
    decimal price;
    if (match.Success){
        double.TryParse(match.Groups[1].Value,out quantity);
        decimal.TryParse(match.Groups[2].Value,out price);
    }

//quantity=45.5
//price=35.45

In the above code the pattern @"\s+([\d.]+)\s*\(\s*([\d.]+)\s*\) matches the value between space and ( into the Groups[1] and matches the value between ( and ) into Groups[2]
