Try this: using System; using System.IO; class Program { static void Main() { int[] numbers1 = {5 4 3 2 9}; int[] numbers2 = {9 5 99 48 25 32}; using(StreamWriter sr = new StreamWriter(file1.txt)) { for(int i = 0; i { sr.Write(numbers1[i]); if (i } } using(StreamWriter sr = new StreamWriter(file2.txt)) { for(int i = 0; i { sr.Write(numbers2[i]); if (i } } FileStream fs = File.Create(file3.txt); fs.Close(); string text1 = File.ReadAllText(file1.txt); string text2 = File.ReadAllText(file2.txt); File.AppendAllText(file3.txt text1); File.AppendAllText(file3.txt   + text2); string text3 = File.ReadAllText(file3.txt); string[] items = text3.Split(' '); int[] numbers3 = new int[items.Length]; for(int i = 0; i { numbers3[i] = int.Parse(items[i]); } Array.Sort(numbers3); using(StreamWriter sr = new StreamWriter(file3.txt)) { for(int i = 0; i { sr.Write(numbers3[i]); if (i } } } }

Just sort the arrays before you write them to the files: int[] numbers1 = {5 4 3 2 9}; int[] numbers2 = {9 5 99 48 25 32}; Array.Sort(numbers1); Array.Sort(numbers2);
