VS C# write a Console Output into a file

Question

I'm a beginner and looking for a solution. Need Help to Write this Code result from Console into the file. Please help. I tried all, but I did not find a good way to solve it.

     namespace ESA2Out {
         class Program {
             static string ESA2In(string verzeichnis, string dateiname, int zeilenlaenge = 0) {
                 string inhalt = string.Empty;
                 string dn = Path.Combine(verzeichnis, dateiname);
                 if (File.Exists(dn)) {
                     // Arrays einlesen
                     using(StreamReader sr = new StreamReader(dn)) {
                         inhalt = sr.ReadToEnd();
                         if (zeilenlaenge > 0) {
                             int anzahl = inhalt.Length / zeilenlaenge;
                             anzahl += inhalt.Length % zeilenlaenge > 0 ? 1 : 0;
                             string[] zeilen = new string[anzahl];
                             // Textzeilen extrahieren
                             for (int i = 0; i < anzahl; i++) {
                                 zeilen[i] = inhalt.Substring(i * zeilenlaenge, zeilenlaenge);
                             }
                             inhalt = string.Join("\r\n", zeilen);
                         }
                     }
                 } else {}
                 return inhalt;
             }

             static void ESA2Out(byte[] data, string verzeichnis, string dateiname) {
                 string dn = Path.Combine(verzeichnis, dateiname);
                 if (!File.Exists(dn)) {
                     using(FileStream fs = File.Create(dn)) {
                         fs.Write(data, 0, data.Length);
                     }
                 } else {}
             }

             static void Main(string[] args) {
                 byte[] array = { 32, 32, 67, 67, 32, 32, 32, 35, 32, 35, 32, 32, 67, 32, 32, 67, 32, 32, 35, 32, 35, 32, 67, 32, 32, 32, 32, 32, 35, 35, 35, 35, 35, 67, 32, 32, 32, 32, 32, 32, 35, 32, 35, 32, 67, 32, 32, 32, 32, 32, 35, 35, 35, 35, 35, 32, 67, 32, 32, 67, 32, 32, 35, 32, 35, 32, 32, 32, 67, 67, 32, 32, 32, 35, 32, 35, 32
                 };
                 ESA2Out(array, @ ".\\", "ESA2.txt");
                 Console.WriteLine();
                 Console.ForegroundColor = ConsoleColor.Green;
                 Console.WriteLine(ESA2In(@ ".\\", "ESA2.txt", 11));
                 Console.ResetColor();
                 Console.ReadKey();
             }
         }
     }

That is the Code, it runs exactly, but now I don't find a way to write the result into the file. If I will open that file in Editor it should show the same as in the Console before.
