如何在C＃中获取ValueTuple的第七个元素？

ValueTuple是C＃7.0中引入的结构，表示值类型Tuple。它允许您存储一个数据集，该数据集包含可能彼此相关或不相关的多个值。 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，例如7-ValueTuple和8-ValueTuple。

句法：

public T7 Item7;

在此，T7是ValueTuple <>结构的字段值。该ValueTuple <>可以是7-ValueTuple或8-ValueTuple。

示例1：在下面的代码中，您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);
    }
}

输出：

C# Topics:
this keyword
Delegates

范例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());
    }
}

输出：

Birth Date: 3-7-1993
Hash Code: -1761317527
