De tekenreeksweergave van dit Tuple<T1> object.

Voorbeelden

In het volgende voorbeeld ziet u de ToString methode.

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)

Opmerkingen

De tekenreeks die door deze methode wordt geretourneerd, heeft het formulier (Item1), waarbij Item1 de waarde van de Item1 eigenschap vertegenwoordigt. Als de waarde Item1 is null, wordt deze weergegeven als String.Empty.
