C# console application log file

To redirect console output to a file rather than the console itself, you'll need to use code such as the following:

using System;
using System.IO;

class Test
{
   static void Main()
   {
       Console.WriteLine("Standard output");
       FileStream fs = new FileStream("test.log", FileMode.Append);
       TextWriter standard = Console.Out; // save standard output

       using (StreamWriter sw = new StreamWriter(fs))
       {
         Console.SetOut(sw); // redirect output to file
         Console.WriteLine("First entry");
         Console.WriteLine("Second entry");
       }

       fs.Close();
       Console.SetOut(standard); // cancel redirection
       Console.WriteLine("Standard output again");
       Console.ReadKey();
   }
}
