Console.WriteLine Method (Object)
Writes the text representation of the specified object, 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( Object value )
Parameters
- value
- Type: System.Object
The value to write.
| Exception | Condition |
|---|---|
| IOException | An I/O error occurred. |
If value is null, only the line terminator is written. Otherwise, the ToString method of value is called to produce its string representation, and the resulting string 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 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 */
