I have a program which outputs various results onto a command line console.

How do I save the output to a text file using a StreamReader or other techniques?

System.Collections.Generic.IEnumerable<String> lines = File.ReadAllLines(@"C:\Test\ntfs8.txt");

foreach (String r in lines.Skip(1))
{
    String[] token = r.Split(',');
    String[] datetime = token[0].Split(' ');
    String timeText = datetime[4];
    String actions = token[2];
    Console.WriteLine("The time for this array is: " + timeText);
    Console.WriteLine(token[7]);
    Console.WriteLine(actions);
    MacActions(actions);
    x = 1;
    Console.WriteLine("================================================");
}

if (x == 2)
{
    Console.WriteLine("The selected time does not exist within the log files!");
}

System.IO.StreamReader reader = ;
string sRes = reader.ReadToEnd();
StreamWriter SW;
SW = File.CreateText("C:\\temp\\test.bodyfile");
SW.WriteLine(sRes);
SW.Close();
Console.WriteLine("File Created");
reader.Close();

Try this example from this article - Demonstrates redirecting the Console output to a file

{
    FileStream ostrm;
    StreamWriter writer;
    TextWriter oldOut = Console.Out;
    try
    {
        ostrm = new FileStream ("./Redirect.txt", FileMode.OpenOrCreate, FileAccess.Write);
        writer = new StreamWriter (ostrm);
    }
    catch (Exception e)
    {
        Console.WriteLine ("Cannot open Redirect.txt for writing");
        Console.WriteLine (e.Message);
        return;
    }
    Console.SetOut (writer);
    Console.WriteLine ("This is a line of text");
    Console.WriteLine ("Everything written to Console.Write() or");
    Console.WriteLine ("Console.WriteLine() will be written to a file");
    Console.SetOut (oldOut);
    writer.Close();
    ostrm.Close();
    Console.WriteLine ("Done");
}

For the question:

How to save Console.Writeline Outputs to text file?

I would use Console.SetOut as others have mentioned.


However, it looks more like you are keeping track of your program flow. I would consider using Debug or Trace for keeping track of the program state.

It works similar the console except you have more control over your input such as WriteLineIf.

Debug will only operate when in debug mode where as Trace will operate in both debug or release mode.

They both allow for listeners such as output files or the console.

TextWriterTraceListener tr1 = new TextWriterTraceListener(System.Console.Out);
Debug.Listeners.Add(tr1);

TextWriterTraceListener tr2 = new TextWriterTraceListener(System.IO.File.CreateText("Output.txt"));
Debug.Listeners.Add(tr2);

 }

Console.SetOut() Method in C#, With the help of this method, a user can specify a StreamWriter as the output Console.WriteLine( "\nGeeksForGeeks" );. // Creating a text file named "Geeks". Any command that has a command window output (no matter how big or small) can be appended with > filename.txt and the output will be saved to the specified text file.
