ภาพรวม
Tuple ที่มี 8 สมาชิกขึ้นไป จะเก็บสมาชิกที่ 8 เป็นต้นไปในคุณสมบัติ Rest (ซึ่งเป็น Tuple อีกที) สามารถเข้าถึงได้ผ่าน Rest.Item1, Rest.Item2 ... หรือ Rest.Rest ซ้อนกัน
ตัวอย่าง 1: Tuple 8 สมาชิก (Item8 อยู่ใน Rest)
using System;
public class Demo {
public static void Main(String[] args) {
var tuple1 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500, 2000);
var tuple2 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500, 2000);
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 1st = " + tuple1.Item1);
Console.WriteLine("Tuple2 Item 1st = " + tuple2.Item1);
Console.WriteLine("Tuple1 Item 2nd = " + tuple1.Item2);
Console.WriteLine("Tuple2 Item 2nd = " + tuple2.Item2);
Console.WriteLine("Tuple1 Item 4th = " + tuple1.Item4);
Console.WriteLine("Tuple2 Item 4th = " + tuple2.Item4);
Console.WriteLine("Tuple1 Item 5th = " + tuple1.Item5);
Console.WriteLine("Tuple2 Item 5th = " + tuple2.Item5);
Console.WriteLine("Tuple1 Item 6th = " + tuple1.Item6);
Console.WriteLine("Tuple2 Item 6th = " + tuple2.Item6);
Console.WriteLine("Tuple1 Item 7th = " + tuple1.Item7);
Console.WriteLine("Tuple2 Item 7th = " + tuple2.Item7);
Console.WriteLine("Tuple1 rest value = " + tuple1.Rest);
Console.WriteLine("Tuple2 rest value = " + tuple2.Rest);
}
}
ผลลัพธ์ตัวอย่าง 1
Is Tuple1 equal to Tuple2? = True HashCode of Tuple1 = 3247155 HashCode of Tuple2 = 3247155 Tuple1 Item 1st = 75 Tuple2 Item 1st = 75 Tuple1 Item 2nd = 200 Tuple2 Item 2nd = 200 Tuple1 Item 4th = 700 Tuple2 Item 4th = 700 Tuple1 Item 5th = 100 Tuple2 Item 5th = 100 Tuple1 Item 6th = 1200 Tuple2 Item 6th = 1200 Tuple1 Item 7th = 1500 Tuple2 Item 7th = 1500 Tuple1 rest value = (2000) Tuple2 rest value = (2000)
ตัวอย่าง 2: Tuple 8 สมาชิก ที่ 8 เป็น Tuple ซ้อน
using System;
public class Demo {
public static void Main(String[] args) {
var tuple1 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500, Tuple.Create("AB", 2000, "CD"));
var tuple2 = Tuple.Create(75, 200, 500, 700, 100, 1200, 1500, Tuple.Create(2500, 3500, 4000, "XY"));
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 1st = " + tuple1.Item1);
Console.WriteLine("Tuple2 Item 1st = " + tuple2.Item1);
Console.WriteLine("Tuple1 Item 2nd = " + tuple1.Item2);
Console.WriteLine("Tuple2 Item 2nd = " + tuple2.Item2);
Console.WriteLine("Tuple1 Item 4th = " + tuple1.Item4);
Console.WriteLine("Tuple2 Item 4th = " + tuple2.Item4);
Console.WriteLine("Tuple1 Item 5th = " + tuple1.Item5);
Console.WriteLine("Tuple2 Item 5th = " + tuple2.Item5);
Console.WriteLine("Tuple1 Item 6th = " + tuple1.Item6);
Console.WriteLine("Tuple2 Item 6th = " + tuple2.Item6);
Console.WriteLine("Tuple1 Item 7th = " + tuple1.Item7);
Console.WriteLine("Tuple2 Item 7th = " + tuple2.Item7);
Console.WriteLine("Tuple1 rest value = " + tuple1.Rest);
Console.WriteLine("Tuple2 rest value = " + tuple2.Rest);
}
}
ผลลัพธ์ตัวอย่าง 2
Is Tuple1 equal to Tuple2? = False HashCode of Tuple1 = -1121878415 HashCode of Tuple2 = -835095725 Tuple1 Item 1st = 75 Tuple2 Item 1st = 75 Tuple1 Item 2nd = 200 Tuple2 Item 2nd = 200 Tuple1 Item 4th = 700 Tuple2 Item 4th = 700 Tuple1 Item 5th = 100 Tuple2 Item 5th = 100 Tuple1 Item 6th = 1200 Tuple2 Item 6th = 1200 Tuple1 Item 7th = 1500 Tuple2 Item 7th = 1500 Tuple1 rest value = ((AB, 2000, CD)) Tuple2 rest value = ((2500, 3500, 4000, XY))
สรุป
- Tuple สูงสุด 7 สมาชิกตรง (Item1-Item7)
- สมาชิกที่ 8 เป็นต้นไปอยู่ใน
Rest(Tuple ต่อยอด) - เข้าถึงสมาชิกที่ 8:
tuple.Rest.Item1, สมาชิกที่ 9:tuple.Rest.Item2ฯลฯ
