Here's the revised code using a StreamReader: using System; using System.IO; class Program { static void Main() { StreamReader sr = new StreamReader(dimitri.txt); int totalDebit = 0; int totalCredit = 0; bool debit = false; bool date = false; string line; while((line = sr.ReadLine()) != null) { if (line.Trim().Length == 0) { continue; } else if (line.StartsWith(Debit)) { debit = true; date = false; Console.WriteLine(Debit:); } else if (line.StartsWith(Credit)) { debit = false; date = false; Console.WriteLine(
Credit:); } else if (debit && !date) { int amount = int.Parse(line); Console.Write( from  amount); totalDebit += amount; date = true; } else if (!debit && !date) { int amount = int.Parse(line); Console.Write( from  amount); totalCredit += amount; date = true; } else if (date) { Console.WriteLine(  line); date = false; } } sr.Close(); Console.WriteLine(
Balance: {0} - {1} = {2} totalDebit totalCredit totalDebit - totalCredit); Console.ReadKey(); } }

Try: using System; using System.IO; class Program { static void Main() { string[] lines = File.ReadAllLines(dimitri.txt); int totalDebit = 0; int totalCredit = 0; bool debit = false; bool date = false; foreach(string line in lines) { if (line.Trim().Length == 0) { continue; } else if (line.StartsWith(Debit)) { debit = true; date = false; Console.WriteLine(Debit:); } else if (line.StartsWith(Credit)) { debit = false; date = false; Console.WriteLine(
Credit:); } else if (debit && !date) { int amount = int.Parse(line); Console.Write( from  amount); totalDebit += amount; date = true; } else if (!debit && !date) { int amount = int.Parse(line); Console.Write( from  amount); totalCredit += amount; date = true; } else if (date) { Console.WriteLine(  line); date = false; } } Console.WriteLine(
Balance: {0} - {1} = {2} totalDebit totalCredit totalDebit - totalCredit); Console.ReadKey(); } }

Use stream reader and read the file assign that to a string and the remaining process is similar as Vulpes coded
