C＃|如何获取元组的其余元素？

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。我们知道，通过使用Item 属性，我们可以获得元组中存在的元素，但是该属性仅适用于七个元素。如果要获取其余元素，则必须使用Rest属性。

Rest属性允许您获取元组中除开始的七个元素以外的其余元素。

句法：

public TRest Rest { get; }

在此， TRest是当前Tuple 对象的其余分量的值。

例子：

// C# program to illustrate the 
// concept of Rest property
using System;
  
class GFG {
  
    // Main Method
    static public void Main()
    {
  
        // Creating 8-tuple
        var stu = Tuple.Create("Mohan", 24, "CSE", 2016,
                               209, 235678909, "C#", 1);
  
        // Accessing first element
        Console.WriteLine("Student Name: " + stu.Item1);
  
        // Accessing Second element
        Console.WriteLine("Student Age: " + stu.Item2);
  
        // Accessing third element
        Console.WriteLine("Student Branch: " + stu.Item3);
  
        // Accessing fourth element
        Console.WriteLine("Student Passing Year: " + stu.Item4);
  
        // Accessing fifth element
        Console.WriteLine("Student Id: " + stu.Item5);
  
        // Accessing sixth element
        Console.WriteLine("Student Contact Number: " + stu.Item6);
  
        // Accessing seventh element
        Console.WriteLine("Student Fav Programming Language: " + stu.Item7);
  
        // Accessing remaining element
        // Using Rest property
        Console.WriteLine("Student Rank: " + stu.Rest);
    }
}

输出：

Student Name: Mohan
Student Age: 24
Student Branch: CSE
Student Passing Year: 2016
Student Id: 209
Student Contact Number: 235678909
Student Fav Programming Language: C#
Student Rank: (1)

注意：您还可以使用Rest属性获取嵌套元组的元素。

例子：

// C# program to illustrate how to access 
// nested tuple using Rest property
using System;
  
class GFG {
  
    // Main Method
    static public void Main()
    {
  
        // Creating 8-tuple
        var stu = Tuple.Create("Guriya", 24, "CSE", 2016, 209, 235678909,
                         1, Tuple.Create("C#", "C++", "Java", "Python"));
  
        // Accessing first element
        Console.WriteLine("Student Name: " + stu.Item1);
  
        // Accessing Second element
        Console.WriteLine("Student Age: " + stu.Item2);
  
        // Accessing third element
        Console.WriteLine("Student Branch: " + stu.Item3);
  
        // Accessing fourth element
        Console.WriteLine("Student Passing Year: " + stu.Item4);
  
        // Accessing fifth element
        Console.WriteLine("Student Id: " + stu.Item5);
  
        // Accessing sixth element
        Console.WriteLine("Student Contact Number: " + stu.Item6);
  
        // Accessing seventh element
        Console.WriteLine("Student Rank: " + stu.Item7);
  
        // Accessing remaining element
        // or accessing the elements of nested tuple
        // Using Rest property
        Console.WriteLine("Student Fav. Programming Language: " + stu.Rest);
    }
}

输出：

Student Name: Guriya
Student Age: 24
Student Branch: CSE
Student Passing Year: 2016
Student Id: 209
Student Contact Number: 235678909
Student Rank: 1
Student Fav. Programming Language: ((C#, C++, Java, Python))
