Definisi

Mengembalikan string yang mewakili nilai instans ini Tuple<T1,T2,T3,T4> .

public:
 override System::String ^ ToString();
public override string ToString ();
override this.ToString : unit -> string
Public Overrides Function ToString () As String

Mengembalikan

Representasi string objek ini Tuple<T1,T2,T3,T4> .

Contoh

Contoh berikut mengilustrasikan ToString metode . Ini menampilkan komponen array objek 4 tuple yang berisi nama kota, sebulan dalam setahun, dan suhu rata-rata tinggi dan rendah untuk bulan itu.

using System;

public class Example
{
   public static void Main()
   {
      Tuple<string, int, int, int>[] temperatures = 
            { Tuple.Create("New York, NY", 4, 61, 43),
              Tuple.Create("Chicago, IL", 2, 34, 18), 
              Tuple.Create("Newark, NJ", 4, 61, 43),
              Tuple.Create("Boston, MA", 6, 77, 59),
              Tuple.Create("Detroit, MI", 9, 74, 53),
              Tuple.Create("Minneapolis, MN", 8, 81, 61) }; 
      // Display the array of 4-tuple objects.
      foreach (var temperature in temperatures)
         Console.WriteLine(temperature.ToString()); 
   }
}
// The example displays the following output:
//       (New York, NY, 4, 61, 43)
//       (Chicago, IL, 2, 34, 18)
//       (Newark, NJ, 4, 61, 43)
//       (Boston, MA, 6, 77, 59)
//       (Detroit, MI, 9, 74, 53)
