Tuple
它用于 -
它有四个属性 -
Item1 - 获取当前Tuple的值
Item2 - 获取当前 Tuple
Item3 - 获取当前 Tuple
Item4 - 获取当前 Tuple
现在让我们看一个在 C# 中实现 4 元组的示例 -
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<string,string,string,string> tuple = new Tuple<string,string,string,string>("nathan", "steve", "katie", "tim");
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
if (tuple.Item1 == "nathan") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
}
if (tuple.Item2 == "jack") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
}
if (tuple.Item3 == "katie") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item3);
}
if (tuple.Item4 == "tom") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item4);
}
}
}这将产生以下输出 -
Value (Item1)= nathan Value (Item2)= steve Value (Item3)= katie Value Value (Item4)= tom Exists: Tuple Value = nathan Exists: Tuple Value = katie
现在让我们看另一个在 C# 中实现 4 元组的示例 -
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int> tuple = new Tuple<int,int,int,int>(100, 150, 300, 450);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
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);
}
}
}这将产生以下输出 -
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 300 Value (Item4)= 450 Exists: Tuple Item 1 = 100
