如何在 C# 中创建 5 元组或五元组?
Tuple<T1, T2, T3, T4, T5> 类表示一个 5 元组,也称为五元组。元组是一个具有元素序列的数据结构。
它有五个属性 -
Item1 - 获取当前 Tuple<T1, T2, T3, T4, T5> 对象第一个组件的值。
Item2 - 获取当前 Tuple<T1, T2, T3, T4, T5> 对象第二个组件的值。
Item3 - 获取当前 Tuple<T1, T2, T3, T4, T5> 对象第三个组件的值。
Item4 - 获取当前 Tuple<T1, T2, T3, T4, T5> 对象第四个组件的值。
Item5 - 获取当前 Tuple<T1, T2, T3, T4, T5> 对象第五个组件的值。
示例
下面我们将看到一个在 C# 中实现 5 元组的示例 -
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int,int> tuple = new Tuple<int,int,int,int,int>(120, 150, 270, 300, 600);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
Console.WriteLine("Value (Item5)= " + tuple.Item5);
if (tuple.Item1 == 100) {
Console.WriteLine("Exists: Tuple Item 1 = " +tuple.Item1);
}
if (tuple.Item2 == 250) {
Console.WriteLine("Exists: Tuple Item 2 = " +tuple.Item2);
}
if (tuple.Item3 == 270) {
Console.WriteLine("Exists: Tuple Item 3 = " +tuple.Item3);
}
if (tuple.Item4 == 300) {
Console.WriteLine("Exists: Tuple Item 4 = " +tuple.Item4);
}
if (tuple.Item5 == 400) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
}
}输出
它会产生以下输出 -
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 300 Value (Item4)= 450 Value (Item5)= 600 Exists: Tuple Item 1 = 100
示例
现在,我们再来看一个在 C# 中实现 5 元组的示例 -
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<string,int,string,int,int> tuple = new Tuple<string,int,string,int,int>("jack", 150, "pete", 300, 600);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
Console.WriteLine("Value (Item5)= " + tuple.Item5);
if (tuple.Item1 == "kevin") {
Console.WriteLine("Exists: Tuple Item 1 = " +tuple.Item1);
}
if (tuple.Item2 == 250) {
Console.WriteLine("Exists: Tuple Item 2 = " +tuple.Item2);
}
if (tuple.Item3 == "pete") {
Console.WriteLine("Exists: Tuple Item 3 = " +tuple.Item3);
}
if (tuple.Item4 == 300) {
Console.WriteLine("Exists: Tuple Item 4 = " +tuple.Item4);
}
if (tuple.Item5 == 400) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
}
}输出
它会产生以下输出 -
Value (Item1)= jack Value (Item2)= 150 Value (Item3)= pete Value (Item4)= 300 Value (Item5)= 600 Exists: Tuple Item 3 = pete Exists: Tuple Item 4 = 300
