如何在C#中获取元组的第一个元素?
要获取元组的第一个元素,代码如下-
示例
using System;public class Demo {
public static void Main(String[] args){
var tuple1 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500);
var tuple2 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500);
Console.WriteLine("Is Tuple1 equal to Tuple2? = "+tuple1.Equals(tuple2));
Console.WriteLine("HashCode of Tuple1 = "+tuple1.GetHashCode());
Console.WriteLine("HashCode of Tuple2 = "+tuple2.GetHashCode());
Console.WriteLine("Tuple1 Item 5th = "+tuple1.Item5);
Console.WriteLine("Tuple2 Item 5th = "+tuple2.Item5);
Console.WriteLine("Tuple1 Item 1st = "+tuple1.Item1);
Console.WriteLine("Tuple2 Item 1st = "+tuple2.Item1);
}
}
输出结果
这将产生以下输出-
Is Tuple1 equal to Tuple2? = True HashCode of Tuple1 = 3231587HashCode of Tuple2 = 3231587
Tuple1 Item 5th = 100
Tuple2 Item 5th = 100
Tuple1 Item 1st = 75
Tuple2 Item 1st = 75
示例
让我们看另一个例子-
using System;public class Demo {
public static void Main(String[] args){
var tuple = Tuple.Create(1200, 1500, 2200, 2700, 3100, 3500, 4500, 5500);
Console.WriteLine("HashCode of Tuple = "+tuple.GetHashCode());
Console.WriteLine("Tuple Item 1st = "+tuple.Item1);
Console.WriteLine("Tuple Item 2nd = "+tuple.Item2);
Console.WriteLine("Tuple Item 3rd = "+tuple.Item3);
Console.WriteLine("Tuple Item 4th = "+tuple.Item4);
Console.WriteLine("Tuple Item 5th = "+tuple.Item5);
Console.WriteLine("Tuple Item 6th = "+tuple.Item6);
Console.WriteLine("Tuple Item 7th = "+tuple.Item7);
}
}
输出结果
这将产生以下输出-
HashCode of Tuple = 49989024Tuple Item 1st = 1200
Tuple Item 2nd = 1500
Tuple Item 3rd = 2200
Tuple Item 4th = 2700
Tuple Item 5th = 3100
Tuple Item 6th = 3500
Tuple Item 7th = 4500
