Console.WriteLine Method (String)

Writes the specified string value, followed by the current line terminator, to the standard output stream.

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

public static void WriteLine (
	string value
)
public static void WriteLine (
	String value
)
public static function WriteLine (
	value : String
)
Not applicable.

Parameters

value

The value to write.

Exception typeCondition

IOException

An I/O error occurred.

If value is a null reference (Nothing in Visual Basic), only the line terminator is written to the standard output stream.

For more information about the line terminator, see the Remarks section of the WriteLine method that takes no parameters.

The following code example illustrates the use of the WriteLine method.

// System.Console.WriteLine

using System;
public class TipCalculator {
    private const double tipRate = 0.18;
    public static int Main(string[] args) {
        double billTotal;
        if (args.Length == 0) {
            Console.WriteLine("usage: TIPCALC total");
            return 1;
        }
        else {
            try {
                billTotal = Double.Parse(args[0]);
            }
            catch(FormatException) {
                Console.WriteLine("usage: TIPCALC total");
                return 1;
            }
            double tip = billTotal * tipRate;
            Console.WriteLine();
            Console.WriteLine("Bill total:\t{0,8:c}", billTotal);
            Console.WriteLine("Tip total/rate:\t{0,8:c} ({1:p1})", tip, tipRate);
            Console.WriteLine(("").PadRight(24, '-'));
            Console.WriteLine("Grand total:\t{0,8:c}", billTotal + tip);
            return 0;
        }
    }
}

/*
Example Output:
---------------

Bill total:       $52.23
Tip total/rate:    $9.40 (18.0 %)
------------------------
Grand total:      $61.63
