Console.Out Property

Definition

Gets the standard output stream.

public:
 static property System::IO::TextWriter ^ Out { System::IO::TextWriter ^ get(); };
public static System.IO.TextWriter Out { get; }
static member Out : System.IO.TextWriter
Public Shared ReadOnly Property Out As TextWriter

Property Value

A TextWriter that represents the standard output stream.

Examples

The following example uses the Out property to display an array containing the names of files in the application's current directory to the standard output device. It then sets the standard output to a file named Files.txt and lists the array elements to the file. Finally, it sets the output to the standard output stream and again displays the array elements to the standard output device.

using System.IO;

public class Example
{
   public static void Main()
   {
      // Get all files in the current directory.
      string[] files = Directory.GetFiles(".");
      Array.Sort(files);

      // Display the files to the current output source to the console.
      Console.Out.WriteLine("First display of filenames to the console:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
      Console.Out.WriteLine();

      // Redirect output to a file named Files.txt and write file list.
      StreamWriter sw = new StreamWriter(@".\Files.txt");
      sw.AutoFlush = true;
      Console.SetOut(sw);
      Console.Out.WriteLine("Display filenames to a file:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
      Console.Out.WriteLine();

      // Close previous output stream and redirect output to standard output.
      Console.Out.Close();
      sw = new StreamWriter(Console.OpenStandardOutput());
      sw.AutoFlush = true;
      Console.SetOut(sw);

      // Display the files to the current output source to the console.
      Console.Out.WriteLine("Second display of filenames to the console:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
   }

Module Example
   Public Sub Main()
      ' Get all files in the current directory.
      Dim files() As String = Directory.GetFiles(".")
      Array.Sort(files)
      
      ' Display the files to the current output source to the console.
      Console.WriteLine("First display of filenames to the console:")
      Array.ForEach(files, Function(s) WriteOutput(s))   
      Console.Out.WriteLine()

      ' Redirect output to a file named Files.txt and write file list.
      Dim sw As StreamWriter = New StreamWriter(".\Files.txt")
      sw.AutoFlush = True
      Console.SetOut(sw)
      Console.Out.WriteLine("Display filenames to a file:")
      Array.ForEach(files, Function(s) WriteOutput(s))
      Console.Out.WriteLine()

      ' Close previous output stream and redirect output to standard output.
      Console.Out.Close()
      sw = New StreamWriter(Console.OpenStandardOutput())
      sw.AutoFlush = True
      Console.SetOut(sw)
           
      ' Display the files to the current output source to the console.
      Console.Out.WriteLine("Second display of filenames to the console:")
      Array.ForEach(files, Function(s) WriteOutput(s))   
   End Sub
   
   Private Function WriteOutput(s As String) As Boolean
      Console.Out.WriteLine(s)
      Return True
   End Function
End Module

Remarks

This property is set to the standard output stream by default. This property can be set to another stream with the SetOut method.

Note that calls to Console.Out.WriteLine methods are equivalent to calls to the corresponding WriteLine methods.
