String

The string representation of this Tuple<T1,T2,T3,T4,T5> object.

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.

using System;

public class Example
{
   public static void Main()
   {
      // 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)
         Console.WriteLine(item.ToString());
   }
}
// The example displays the following output:
//       (California, 29760021, 33871648, 4111627, 13.8)
//       (Illinois, 11430602, 12419293, 988691, 8.6)
//       (Washington, 4866692, 5894121, 1027429, 21.1)

open System

// Define array of tuples reflecting population change by state, 1990-2000.
let 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 item in populationChanges do
    printfn $"{item.ToString()}"
// The example displays the following output:
//       (California, 29760021, 33871648, 4111627, 13.8)
//       (Illinois, 11430602, 12419293, 988691, 8.6)
//       (Washington, 4866692, 5894121, 1027429, 21.1)

Module Example
   Public Sub Main()
      ' 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
         Console.WriteLine(item.ToString())
      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)

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 null, it is represented as String.Empty.
