Tuple<T1, T2, T3> 类表示 3 元组，也称为三重元组。元组是一种具有元素序列的数据结构。
它用于 −
- 更轻松地访问数据集。
- 更轻松地操作数据集。
- 表示单个数据集。
- 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 3 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
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
现在让我们看另一个在 C# 中实现 3 元组的示例 −
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
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
