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。 Item7属性用于获取给定元组的第七个元素。它不适用于1元组,2元组,3元组,4元组,5元组和6元组,但适用于所有其他其余元组。
句法:
public T7 Item7 { get; }
在此, T7是当前Tuple <>对象的第七个分量的值。该Tuple <>可以是7元组,也可以是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七个元素。
// C# program to illustrate how to get
// the seventh element of the tuple
using System;
class GFG {
// Main method
static public void Main()
{
// Taking 7-tuple
var st7 = Tuple.Create("Rohit", 21, "IT", 2017,
"21-Apr-1994", 384749829, 1);
Console.WriteLine("Student-7 Position.: " + st7.Item7);
// Taking 8-tuple
var st8 = Tuple.Create("Manita", 24, "CSE", 2013,
"03-Aug-1991", 235678909, 2, "C#");
Console.WriteLine("Student-8 Position: " + st8.Item7);
}
}
输出:
Student-7 Position.: 1
Student-8 Position: 2
注意:您还可以通过使用GetType()方法或使用Type.GetGenericArguments方法来获取元组的第七个组件的类型。
例子:
// C# program to illustrate how to get the
// type of the Seventh element of the tuple
using System;
class GFG{
// Main method
static public void Main (){
// Taking 7-tuple
var stu7 = Tuple.Create("Riya", 24, "CSE", 2015, 102, 230134832, "DSA");
Console.WriteLine("Student-7 Favourite Subject: "+stu7.Item7);
// Get the type of Item7
// Using GetType() method
Console.WriteLine("Type of Item7: "+stu7.Item7.GetType());
// Get the type of Item7
// Using Type.GetGenericArguments method
Type stu7type = stu7.GetType();
Console.WriteLine("Type of Item7: "+stu7type.GetGenericArguments()[6]);
Console.WriteLine();
}
}
输出:
Student-7 Favourite Subject: DSA
Type of Item7: System.String
Type of Item7: System.String
