C# |如何获取元组的剩余元素？
Tuple 是一种数据结构，它为您提供了最简单的方法来表示具有多个值的数据集，这些值可能彼此相关，也可能彼此不相关。我们知道，通过使用项<元素编号> 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。如果你想得到剩余的元素，那么你必须去休息属性。
Rest 属性允许您获取元组的剩余元素，而不是开始的七个元素。
语法:
public TRest Rest { get; }
这里， TRest 是当前元组< T1、T2、T3、T4、T5、T6、T7、TRest > 对象剩余组件的值。
示例:
// 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);
}
}
Output:
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:还可以使用 Rest 属性获取嵌套元组的元素。
示例:
// 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);
}
}
Output:
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))
