範例

以下範例說明此 ToString 方法。 它顯示一個包含城市名稱、一年中的月份，以及該月份最高與最低平均溫度的四元組物件陣列的組成部分。

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)
//       (Minneapolis, MN, 8, 81, 61)

open System

let 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.
for temperature in temperatures do
    printfn $"{temperature}"
// The example displays the following output:
//       (New York, NY, 4, 61, 43)
//       (Chicago, IL, 2, 34, 18)
//       (Newark, NJ, 4, 61, 43)

//       (Detroit, MI, 9, 74, 53)
//       (Minneapolis, MN, 8, 81, 61)

      For Each temperature In temperatures
         Console.WriteLine(temperature.ToString())
      Next

備註

此方法回傳的字串形式為 （Item1， Item2， Item3， Item4），其中 Item1、Item2、Item3 和 Item4 分別代表 ， Item1， Item2， 和 Item3 屬性的Item4值。 若任一性質值為 null，則表示為 String.Empty。
