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, T2, T3, T4, T5> object.

Remarks

The string returned by this method takes the form (Item1, Item2, Item3, Item4, Item5), where Item1, Item2, Item3, Item4, and Item5 represent the values of the Item1, Item2, Item3, Item4, and Item5 properties, respectively. If any of the property values is nulla null reference (Nothing in Visual Basic), it is represented as String.Empty.

Examples

The following example illustrates the ToString method. It displays an array of 5-tuple objects that contain the name of a state in the United States, its population in 1990 and 2000, its population change in this 10-year period, and the annual rate of population change.

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Define array of tuples reflecting population change by state, 1990-2000.
      Dim populationChanges() = _
            { Tuple.Create("California", 29760021, 33871648, 4111627, 13.8), _
              Tuple.Create("Illinois", 11430602, 12419293, 988691, 8.6), _
              Tuple.Create("Washington", 4866692, 5894121, 1027429, 21.1) }
      ' Display each tuple.
      For Each item In populationChanges
         outputBlock.Text &= item.ToString() & vbCrLf
      Next
   End Sub
End Module
' The example displays the following output:
'       (California, 29760021, 33871648, 4111627, 13.8)
'       (Illinois, 11430602, 12419293, 988691, 8.6)
'       (Washington, 4866692, 5894121, 1027429, 21.1)
using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Define array of tuples reflecting population change by state, 1990-2000.
      Tuple<string, int, int, int, double>[] populationChanges = 
           { Tuple.Create("California", 29760021, 33871648, 4111627, 13.8), 
             Tuple.Create("Illinois", 11430602, 12419293, 988691, 8.6), 
             Tuple.Create("Washington", 4866692, 5894121, 1027429, 21.1) };
      // Display each tuple.
      foreach (var item in populationChanges)
         outputBlock.Text += item.ToString() + "\n";
   }
