如何在 C# 中获取 ValueTuple 的第七个元素？
原文:https://www . geeksforgeeks . org/如何获取 c-sharp 中的第七个值元素 tuple/
ValueTuple 是 C# 7.0 中引入的一个结构，代表值类型 Tuple。它允许您存储包含多个值的数据集，这些值可能彼此相关，也可能彼此不相关。 Item7 属性用于获取给定值元组的第七个未命名元素。它适用于每个值元组，如 7 值元组和 8 值元组。
语法:
public T7 Item7;
这里，T7 是 ValueTuple <>结构的字段值。该值元组<>可以是 7 值元组，也可以是 8 值元组。
示例 1: 在下面的代码中，可以看到我们正在访问每个值元组的第七个元素。
// C# program to illustrate how to get
// the seventh element of value tuple
using System;
class GFG {
// Main Method
static public void Main()
{
Console.WriteLine("C# Topics:");
// Creating a value tuple with seven elements
var ValTpl7 = ValueTuple.Create("Inheritance ", "Constructors",
"Encapsulation", "Abstraction", "Static Class",
"Partial Classes", "this keyword");
// Accessing the seventh element of
// 7-ValueTuple using Item property
Console.WriteLine(ValTpl7.Item7);
// Creating a value tuple with eight elements
var ValTpl8 = ValueTuple.Create("Methods", "Method Hiding",
"Optional Parameters", "Anonymous Method",
"Partial Methods", "Local Function", "Delegates",
"Destructors");
// Accessing the seventh element of
// 8-ValueTuple using Item property
Console.WriteLine(ValTpl8.Item7);
}
}
Output:
C# Topics:
this keyword
Delegates
例 2:
// C# program to get the hash code of
// seventh element in a value tuple
using System;
class GFG {
// Main method
static public void Main()
{
// Creating 7-ValueTuple
var My_Value_Tuple = (1004, "Rohit", "Computer Science",
24, "C#", 2017, "3-7-1993");
// Accessing seventh element
// of the value tuple
Console.WriteLine("Birth Date: {0}",
My_Value_Tuple.Item7);
// Getting the hashcode of
// the seventh element
Console.WriteLine("Hash Code: {0}",
My_Value_Tuple.Item7.GetHashCode());
}
}
Output:
Birth Date: 3-7-1993
Hash Code: -1761317527
