法律研究如何在 C# 中获取元组的第一个元素？
如需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
这将产生以下输出 −
Is Tuple1 equal to Tuple2? = True HashCode of Tuple1 = 3231587 HashCode of Tuple2 = 3231587 Tuple1 Item 5th = 100 Tuple2 Item 5th = 100 Tuple1 Item 1st = 75 Tuple2 Item 1st = 75
示例
让我们看另一个示例 −
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
这将产生以下输出 −
HashCode of Tuple = 49989024 Tuple 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
