Tuple<T1>.ToString Tuple<T1>.ToString Tuple<T1>.ToString Tuple<T1>.ToString Method

定义

返回表示此 Tuple<T1> 实例的值的字符串。Returns a string that represents the value of this Tuple<T1> instance.

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

返回

Tuple<T1> 对象的字符串表示形式。The string representation of this Tuple<T1> 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()
   {
      var tuple1Double = Tuple.Create(3.456e-18);
      DisplayTuple(tuple1Double);
      
      var tuple1String = Tuple.Create("Australia");
      DisplayTuple(tuple1String);
      
      var tuple1Bool = Tuple.Create(true);
      DisplayTuple(tuple1Bool);
      
      var tuple1Char = Tuple.Create('a');
      DisplayTuple(tuple1Char);
   }

   private static void DisplayTuple(object obj)
   {
      Console.WriteLine(obj.ToString());
   }
}
// The example displays the following output:
//       (3.456E-18)
//       (Australia)
//       (True)
//       (a)
Module Example
   Public Sub Main()
      Dim tuple1Double = Tuple.Create(3.456e-18)
      DisplayTuple(tuple1Double)
      
      Dim tuple1String = Tuple.Create("Australia")
      DisplayTuple(tuple1String)
      
      Dim tuple1Bool = Tuple.Create(True)
      DisplayTuple(tuple1Bool)
      
      Dim tuple1Char = Tuple.Create("a"c)
      DisplayTuple(tuple1Char)
   End Sub
   
   Private Sub DisplayTuple(obj As Object)
      Console.WriteLine(obj.ToString())
   End Sub
End Module
' The example displays the following output:
'       (3.456E-18)
'       (Australia)
'       (True)
'       (a)

注解

此方法返回的字符串采用窗体 (Item1), 其中Item1表示Item1属性的值。The string returned by this method takes the form (Item1), where Item1 represents the value of the Item1 property. 如果的Item1值为null, 则将其表示为String.EmptyIf the value of Item1 is null, it is represented as String.Empty.
