Tuple<T1>.ToString Method

Returns a string that represents the value of this Tuple<T1> instance.

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

Syntax

'Declaration
Public Overrides Function ToString As String
public override string ToString()

Return Value

Type: System.String
The string representation of this Tuple<T1> object.

Remarks

The string returned by this method takes the form (Item1), where Item1 represents the value of the Item1 property. If the value of Item1 is nulla null reference (Nothing in Visual Basic), it is represented as String.Empty.

Examples

The following example illustrates the ToString method.

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim tuple1Double = Tuple.Create(3.456E-18)
      DisplayTuple(outputBlock, tuple1Double)

      Dim tuple1String = Tuple.Create("Australia")
      DisplayTuple(outputBlock, tuple1String)

      Dim tuple1Bool = Tuple.Create(True)
      DisplayTuple(outputBlock, tuple1Bool)

      Dim tuple1Char = Tuple.Create("a"c)
      DisplayTuple(outputBlock, tuple1Char)
   End Sub

   Private Sub DisplayTuple(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal obj As Object)
      outputBlock.Text &= obj.ToString() & vbCrLf
   End Sub
End Module
' The example displays the following output:
'       (3.456E-18)
'       (Australia)
'       (True)
'       (a)
using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      var tuple1Double = Tuple.Create(3.456e-18);
      DisplayTuple(outputBlock, tuple1Double);

      var tuple1String = Tuple.Create("Australia");
      DisplayTuple(outputBlock, tuple1String);

      var tuple1Bool = Tuple.Create(true);
      DisplayTuple(outputBlock, tuple1Bool);

      var tuple1Char = Tuple.Create('a');
      DisplayTuple(outputBlock, tuple1Char);
   }

   private static void DisplayTuple(System.Windows.Controls.TextBlock outputBlock, object obj)
   {
      outputBlock.Text += obj.ToString() + "\n";
   }
}
// The example displays the following output:
//       (3.456E-18)
//       (Australia)
//       (True)
//       (a)
