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

返回

Tuple<T1,T2,T3> 对象的字符串表示形式。The string representation of this Tuple<T1,T2,T3> object.

示例

下面的示例演示 ToString 方法。The following example illustrates the ToString method.

using System;

public class Example
{
   public static void Main()
   {
      Tuple<string, double, int>[] scores = 
                    { Tuple.Create("Jack", 78.8, 8),
                      Tuple.Create("Abbey", 92.1, 9), 
                      Tuple.Create("Dave", 88.3, 9),
                      Tuple.Create("Sam", 91.7, 8), 
                      Tuple.Create("Ed", 71.2, 5),
                      Tuple.Create("Penelope", 82.9, 8),
                      Tuple.Create("Linda", 99.0, 9),
                      Tuple.Create("Judith", 84.3, 9) };
      Array.Sort(scores);
      foreach (var score in scores)
         Console.WriteLine(score.ToString());
   }
}
// The example displays the following output;
//    (Abbey, 92.1, 9)
//    (Dave, 88.3, 9)
//    (Ed, 71.2, 5)
//    (Jack, 78.8, 8)
//    (Judith, 84.3, 9)
//    (Linda, 99, 9)
//    (Penelope, 82.9, 8)
//    (Sam, 91.7, 8)
Module Example
   Public Sub Main()
      Dim scores() = 
                { Tuple.Create("Jack", 78.8, 8),
                  Tuple.Create("Abbey", 92.1, 9), 
                  Tuple.Create("Dave", 88.3, 9),
                  Tuple.Create("Sam", 91.7, 8), 
                  Tuple.Create("Ed", 71.2, 5),
                  Tuple.Create("Penelope", 82.9, 8),
                  Tuple.Create("Linda", 99.0, 9),
                  Tuple.Create("Judith", 84.3, 9) }
      Array.Sort(scores)
      For Each score In scores
         Console.WriteLine(score.ToString())
      Next
   End Sub
End Module
' The example displays the following output;
'    (Abbey, 92.1, 9)
'    (Dave, 88.3, 9)
'    (Ed, 71.2, 5)
'    (Jack, 78.8, 8)
'    (Judith, 84.3, 9)
'    (Linda, 99, 9)
'    (Penelope, 82.9, 8)
'    (Sam, 91.7, 8)

注解

此方法返回的字符串采用格式(Item1Item2Item3),其中Item1Item2Item3分别表示 Item1Item2Item3 属性的值。The string returned by this method takes the form (Item1, Item2, Item3), where Item1, Item2, and Item3 represent the values of the Item1, Item2, and Item3 properties, respectively. 如果 null任何属性值,则将其表示为 String.EmptyIf any of the property values is null, it is represented as String.Empty.
