如何在C#中创建三元组或三元组?
Tuple<T1,T2,T3>类表示3元组,称为三元组。元组是具有一系列元素的数据结构。
它用于-
轻松访问数据集。
更容易操作数据集。
代表一组数据。
从方法返回多个值
将多个值传递给方法
示例
现在让我们看一个在C#中实现三元组的示例-
using System; public class Demo { public static void Main(string[] args) { Tuple<int,string,string> tuple = new Tuple<int,string,string>(35, "steve", "katie"); Console.WriteLine("Value (Item1)= " + tuple.Item1); Console.WriteLine("Value (Item2)= " + tuple.Item2); Console.WriteLine("Value (Item3)= " + tuple.Item3); if (tuple.Item1 == 35) { 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); } } }
输出结果
这将产生以下输出-
Value (Item1)= 35 Value (Item2)= steve Value (Item3)= katie Exists: Tuple Value = 35 Exists: Tuple Value = katie
示例
现在让我们来看另一个示例,以在C#中实现三元组-
using System; public class Demo { public static void Main(string[] args) { Tuple<string,string,string> tuple = new Tuple<string,string,string>("nathan", "steve", "katie"); Console.WriteLine("Value (Item1)= " + tuple.Item1); Console.WriteLine("Value (Item2)= " + tuple.Item2); Console.WriteLine("Value (Item3)= " + tuple.Item3); 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); } } }
输出结果
这将产生以下输出-
Value (Item1)= nathan Value (Item2)= steve Value (Item3)= katie Exists: Tuple Value = nathan Exists: Tuple Value = katie
