C＃|如何获得元组的第三个元素？

元组是一种数据结构，它为您提供最简单的方式来表示一个数据集，该数据集具有多个可能/可能彼此不相关的值。 Item3属性用于获取给定元组的第三个元素。它不适用于1元组，2元组，但适用于所有其他其余元组。

句法：

public T3 Item3 { get; }

在此， T3是当前Tuple <>对象的第三部分的值。该元组<>可以是3元组，或4元组，或5元组，或6元组，或7元组或8元组。

示例：在下面的代码中，您可以看到我们正在访问每个元组的第三个元素。

// C# program to illustrate how to get 
// the third element of the tuple
using System;
  
class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Taking 3-tuple
        var st3 = Tuple.Create("Soniya", 30, "CSE");
        Console.WriteLine("Student-3 Branch: " + st3.Item3);
  
        // Taking 4-tuple
        var st4 = Tuple.Create("Rohan", 29, "EC", 2015);
        Console.WriteLine("Student-4 Branch: " + st4.Item3);
  
        // Taking 5-tuple
        var st5 = Tuple.Create("Siya", 22, "EEE", 2017,
                                           "20-Mar-1993");
  
        Console.WriteLine("Student-5 Branch: " + st5.Item3);
  
        // Taking 6-tuple
        var st6 = Tuple.Create("Riya", 24, "ME", 2015,
                               "30-May-2015", 230134832);
  
        Console.WriteLine("Student-6 Branch: " + st6.Item3);
  
        // Taking 7-tuple
        var st7 = Tuple.Create("Rohit", 21, "IT", 2017, 
                        "21-Apr-1998", 384749829, 20000);
  
        Console.WriteLine("Student-7 Branch: " + st7.Item3);
  
        // Taking 8-tuple
        var st8 = Tuple.Create("Manita", 24, "CSE", 2016, 
                   "03-Aug-1991", 235678909, 34000, "C#");
  
        Console.WriteLine("Student-8 Branch: " + st8.Item3);
    }
}

输出：

Student-3 Branch: CSE
Student-4 Branch: EC
Student-5 Branch: EEE
Student-6 Branch: ME
Student-7 Branch: IT
Student-8 Branch: CSE
