Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public static TextWriter Out { get; }
/** @property */
public static TextWriter get_Out ()

public static function get Out () : TextWriter

Property Value

A TextWriter that represents the standard output stream.

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

The following code example illustrates the use of the Out property.

public class InsertTabs {
    private const int tabSize = 4;
    private const string usageText = "Usage: INSERTTABS inputfile.txt outputfile.txt";
    public static int Main(string[] args) {
        StreamWriter writer = null;

        if (args.Length < 2) {
            Console.WriteLine(usageText);
            return 1;
        }

        try {
            writer = new StreamWriter(args[1]);
            Console.SetOut(writer);
            Console.SetIn(new StreamReader(args[0]));
        }
        catch(IOException e) {
            TextWriter errorWriter = Console.Error;
            errorWriter.WriteLine(e.Message);
            errorWriter.WriteLine(usageText);
            return 1;            
        }
        string line;
        while ((line = Console.ReadLine()) != null) {
            string newLine = line.Replace(("").PadRight(tabSize, ' '), "\t");
            Console.WriteLine(newLine);
        }

        // completion message can be displayed.
