Console.WriteLine Method (Int64)

Writes the text representation of the specified 64-bit signed integer value, followed by the current line terminator, to the standard output stream.

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

[HostProtectionAttribute(SecurityAction.LinkDemand, UI = true)]
public static void WriteLine(
	long value
)

Parameters

value
Type: System.Int64

The value to write.

ExceptionCondition
IOException

An I/O error occurred.

NoteNote:

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The text representation of value is produced by calling the Int64.ToString method.

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
