It is used to get the standard output stream.

- OpenStandardOutput() Method
- OpenStandardOutput(int32) Method
OpenStandardOutput() Method
It is used to get the standard output stream.
Syntax: public static System.IO.Stream OpenStandardOutput (); Parameters: This method does not accepts any parameter. Return value: This method returns the standard output stream.Example:
// C# program to illustrate the
// Console.OpenStandardOutput()
// method
using System;
class GFG
{
static void Main(string[] args)
{
// use of Console.OpenStandardOutput() method
// to print the Geeksforgeeks
// BeginWrite returns an IAsyncResult that represents
// the asynchronous write
// int32 value like 071, 101 represents the
// ascii value of Geeksforgeeks
if (System.Console.OpenStandardOutput().BeginWrite(new byte[] { 071, 101,101,
107,115, 102, 111, 114, 103, 101,101,
107,115, 0 },0,
13, null, null).AsyncWaitHandle.WaitOne())
{
}
}
}
Geeksforgeeks
OpenStandardOutput(Int32) Method
It is used to get the standard output stream, which is set to a specified buffer size.
Syntax:public static System.IO.Stream OpenStandardOutput (int bufferSize); Parameters: This method accepts the following parameter.Example: It replaces 2 consecutive space characters in a string with a tab character.Return value: This method returns the standard output stream. Exception: This method will give ArgumentOutOfRangeException if the buffersize is less than or equal to zero.
- bufferSize: This parameter is the internal stream buffer size.
// C# program to illustrate the
// Console.OpenStandardOutput(int32) method
using System;
using System.IO;
public class GFG
{
// size of tab
private const int Val1 = 2;
// working string
private const string Val_Text = "Geeks for Geeks";
// main function
public static int Main(string[] args)
{
// check for the argument
if (args.Length < 2)
{
Console.WriteLine(Val_Text);
return 1;
}
try
{
// replacing space characters in a string with
// a tab character
using (var wrt1 = new StreamWriter(args[1]))
{
using (var rdr1 = new StreamReader(args[0]))
{
Console.SetOut(wrt1);
Console.SetIn(rdr1);
string line;
while ((line = Console.ReadLine()) != null)
{
string newLine = line.Replace(("").PadRight(Val1, ' '), "\t");
Console.WriteLine(newLine);
}
}
}
}
catch(IOException e)
{
TextWriter errwrt = Console.Error;
errwrt.WriteLine(e.Message);
return 1;
}
// use of OpenStandardOutput() method
var standardOutput = new StreamWriter(Console.OpenStandardOutput());
standardOutput.AutoFlush = true;
// set the output
Console.SetOut(standardOutput);
Console.WriteLine("OpenStandardOutput Example");
return 0;
}
}
Output:
Geeks for Geeks
