Writing Console.Out for Different Output Files

Question

I am trying to redirect Console.Outto two text files using Console.SetOut.

Console.SetOut(File.CreateText("c:\\del1.txt"));
Console.WriteLine(string1);
...
Console.SetOut(File.CreateText("c:\\del2.txt"));
Console.WriteLine(string2);

With this redirection, two text files are created without any data. This works fine if I comment on the second redirect. How can I redirect output to different files using Console.SetOut.

Edit1: the program ends without any errors, does it guarantee that all file streams will be closed and reset?

Edit2: Thanks to everyone who answered my question, I was able to find a solution without changing the code and add two additional lines to close the file stream.           Console.Out.Close();

Can anyone explain why the file streams are not closed and not cleaned after the program terminates?

Answer 1

- IMO, TextWriter , . . stdout, .

using(var file = File.CreateText(@"c:\del1.txt")) {
    file.WriteLine(string1);
}
using(var file = File.CreateText(@"c:\del2.txt")) {
    file.WriteLine(string2);
}

- , TextWriter, .

Answer 2

, . File.AppendAllText ?

- , using.

:

:

class DynamicConsole : TextWriter
{
  readonly TextWriter orig;
  readonly TextWriter output;

  public DynamicConsole(string filename)
  {
     orig = Console.Out;
    output = File.AppendText(filename);
    Console.SetOut(output);
  }

  public override System.Text.Encoding Encoding
  {
    get { return output.Encoding; }
  }

  public override void Write(char value)
  {
    output.Write(value);
  }

  protected override void Dispose(bool disposing)
  {
    Console.SetOut(orig);
    output.Dispose();
  }
}

( ):

Console.WriteLine("Real 1");

using (new DynamicConsole("Foo.txt"))
{
  Console.WriteLine("Moo");

  using (new DynamicConsole("Bar.txt"))
  {
    Console.WriteLine("Ork");
  }

  Console.WriteLine("Bar");
}

Console.WriteLine("Real 2");

Console:

Real 1
Real 2

Foo.txt:

Moo
Bar

Bar.txt:

Ork

    using (TextWriter file1 = File.CreateText("c:\\del1.txt")) {
        using (TextWriter file2 = File.CreateText("c:\\del2.txt")) {
            Console.SetOut(file1);
            Console.WriteLine("test1");
            Console.SetOut(file2);
            Console.WriteLine("test2");
        }
    }
