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

傳回

Tuple<T1,T2,T3,T4,T5> 物件的字串表示。The string representation of this Tuple<T1,T2,T3,T4,T5> object.

範例

下列範例說明ToString方法。The following example illustrates the ToString method. 它會顯示5個元組物件的陣列, 其中包含美國的狀態名稱、其在1990和2000中的人口、在此10年期間內的人口變更, 以及人口變更的年度費率。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)
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)

備註

這個方法所傳回的字串採用的格式為 (Item1Item2Item3tuple.item4Item5), 其中Item1Item2Item3tuple.item4Item5代表下列各項的值:Item1、 、Item2 、和Item5屬性。 Item3 Item4The 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. 如果任何屬性值為null, 則會以String.Empty表示。If any of the property values is null, it is represented as String.Empty.
