Contoh

Contoh berikut mengilustrasikan ToString metode .

using System;

public class Example
{
   public static void Main()
   {
      var tuple1Double = Tuple.Create(3.456e-18);
      DisplayTuple(tuple1Double);
      
      var tuple1String = Tuple.Create("Australia");
      DisplayTuple(tuple1String);
      
      var tuple1Bool = Tuple.Create(true);
      DisplayTuple(tuple1Bool);
      
      var tuple1Char = Tuple.Create('a');
      DisplayTuple(tuple1Char);
   }

   private static void DisplayTuple(object obj)
   {
      Console.WriteLine(obj.ToString());
   }
}
// The example displays the following output:
//       (3.456E-18)
//       (Australia)
//       (True)
//       (a)

open System

let displayTuple obj =
    // String interpolation implicitly calls .ToString().
    printfn $"{obj}"

let tuple1Double = Tuple.Create 3.456e-18
displayTuple tuple1Double

let tuple1String = Tuple.Create "Australia"
displayTuple tuple1String

let tuple1Bool = Tuple.Create true
displayTuple tuple1Bool

let tuple1Char = Tuple.Create 'a'
displayTuple tuple1Char
// The example displays the following output:
//       (3.456E-18)
//       (Australia)
//       (True)
//       (a)

Module Example
   Public Sub Main()
      Dim tuple1Double = Tuple.Create(3.456e-18)
      DisplayTuple(tuple1Double)
      
      Dim tuple1String = Tuple.Create("Australia")
      DisplayTuple(tuple1String)
      
      Dim tuple1Bool = Tuple.Create(True)
      DisplayTuple(tuple1Bool)
      
      Dim tuple1Char = Tuple.Create("a"c)
      DisplayTuple(tuple1Char)
   End Sub
   
   Private Sub DisplayTuple(obj As Object)
      Console.WriteLine(obj.ToString())
   End Sub
End Module
' The example displays the following output:
'       (3.456E-18)
'       (Australia)
'       (True)
'       (a)

Keterangan

String yang dikembalikan oleh metode ini mengambil formulir (Item1), di mana Item1 mewakili nilai Item1 properti . Jika nilai Item1 adalah null, nilai tersebut dinyatakan sebagai String.Empty.
