ในการรับหรือตั้งค่าองค์ประกอบกินดัชนีที่ระบุในรายการ รหัสจะเป็นดังนี้ -
ตัวอย่าง
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { List<String> list = new List<String>(); list.Add("100"); list.Add("200"); list.Add("300"); list.Add("400"); list.Add("500"); list.Add("600"); list.Add("700"); list.Add("800"); list.Add("900"); list.Add("1000"); Console.WriteLine("Element at index 0 = " + list[0]); Console.WriteLine("Element at index 1 = " + list[1]); Console.WriteLine("Element at index 2 = " + list[2]); Console.WriteLine("Element at index 3 = " + list[3]); Console.WriteLine("Element at index 4 = " + list[4]); Console.WriteLine("Element at index 5 = " + list[5]); Console.WriteLine("Element at index 6 = " + list[6]); Console.WriteLine("Element at index 7 = " + list[7]); } }
ผลลัพธ์
สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -
Element at index 0 = 100 Element at index 1 = 200 Element at index 2 = 300 Element at index 3 = 400 Element at index 4 = 500 Element at index 5 = 600 Element at index 6 = 700 Element at index 7 = 800
ตัวอย่าง
เรามาดูตัวอย่างกัน −
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { List<String> list = new List<String>(); list.Add("100"); list.Add("200"); list.Add("300"); list.Add("400"); list.Add("500"); list.Add("600"); list.Add("700"); list.Add("800"); list.Add("900"); list.Add("1000"); Console.WriteLine("Element at index 0 = " + list[0]); Console.WriteLine("Element at index 1 = " + list[1]); Console.WriteLine("Element at index 2 = " + list[2]); Console.WriteLine("Element at index 3 = " + list[3]); Console.WriteLine("Element at index 4 = " + list[4]); Console.WriteLine("Element at index 5 = " + list[5]); Console.WriteLine("Element at index 6 = " + list[6]); Console.WriteLine("Element at index 7 = " + list[7]); list[3] = "450"; Console.WriteLine("Element at index 3 [UPDATED] = " + list[3]); } }
ผลลัพธ์
สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -
Element at index 0 = 100 Element at index 1 = 200 Element at index 2 = 300 Element at index 3 = 400 Element at index 4 = 500 Element at index 5 = 600 Element at index 6 = 700 Element at index 7 = 800 Element at index 3 [UPDATED] = 450
