1000 hexadecimal is not a lot I converted 10000 didn't even take a second.. try this code : List convertedValues = new List (); List myList = File.ReadAllLines(@hex.txt).ToList(); foreach (string hex in myList) { convertedValues.Add(Convert.ToInt64(hex 16).ToString()); } File.WriteAllLines(@decimal.txt convertedValues.ToArray()); Console.WriteLine(Done); Console.ReadKey();

Hello Ali Thanks for the response.The below code is the one which i was using.Am facing a problem while trying to convert bulk amount .When given some 10 values the result is all fine but when given in bulk (1000 values) am not getting the decimal values for all the inputs given. Could you please let me know if there is any size constraint or so that it's not displaying the result for all the values? The other problem is the result is in the random manner.Donno y??please help me in this too!!! using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO; namespace Sample { class Program { static void ReadFile(string filename) { FileStream fs = new FileStream(filename FileMode.Open FileAccess.Read); StreamReader reader = new StreamReader(filename); string line; while ((line = reader.ReadLine()) != null) { string hexNumber = line; hexNumber = hexNumber.Replace(x string.Empty); long result = 0; long.TryParse(hexNumber System.Globalization.NumberStyles.HexNumber null out result); Console.WriteLine( + result); } } static void Main(string[] args) { string filename = @D:\Filename.txt; ReadFile(filename); } } }

Do you have problem with converting values or reading it from text file? I think you can create a console application read the file convert it and write to a different file.. Convert.ToInt64(00037FFED3837801 16) displays 985157377161217 you can use it.. you could read text file with File.ReadAllLines method... you can save text file with File.WriteAllLines Also check this link for converting between hex and decimal: http://stackoverflow.com/questions/74148/how-to-convert-numbers-between-hexadecimal-and-decimal-in-c
