Public Shared Sub WriteLine (
	value As ULong


Type: System.UInt64

The value to write.

Exception Condition

The text representation of value is produced by calling the UInt64.ToString method.

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

The following example is a tip calculator that calculates an 18% tip and uses the WriteLine method to display the amount of the original charge, the amount of the tip, and the total amount. The example is a console application that requires the user to supply the amount of the original charge as a command-line parameter.

Public Class TipCalculator
   Private Const tipRate As Double = 0.18

   Public Shared Sub Main()
      System.Environment.ExitCode = Calculator(System.Environment.GetCommandLineArgs())
   End Sub

   Public Shared Function Calculator(args() As String) As Integer
      Dim billTotal As Double
      If args.Length < 2 Then
         Console.WriteLine("usage: TIPCALC total")
         Return 1
         If Not Double.TryParse(args(1), billTotal) Then
            Console.WriteLine("usage: TIPCALC total")
            Return 1
         End If

         Dim tip As Double = billTotal * tipRate
         Console.WriteLine("Bill total:{1}{0,8:c}", billTotal, vbTab)
         Console.WriteLine("Tip total/rate:{2}{0,8:c} ({1:p1})", tip, tipRate, vbTab)
         Console.WriteLine("".PadRight(24, "-"c))
         Console.WriteLine("Grand total:{1}{0,8:c}", billTotal + tip, vbTab)
         Return 0
      End If
   End Function 
End Class 

'Example Output:
' >tipcalc 52.23
' Bill total:       $52.23
' Tip total/rate:    $9.40 (18.0 %)
' ------------------------
' Grand total:      $61.63
