法律學獲取或設定在 C# 中 List 的指定索引處的元素
獲取或設定列表中特定索引處的元素，程式碼如下 -
示例
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]);
}
}輸出
這會產生以下輸出 -
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
示例
讓我們看另一個示例 -
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]);
}
}輸出
這會產生以下輸出 -
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
