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();     } }

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

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();     } }
