如何在 C# 中將集合的元素插入到指定索引處的列表中?
要將集合的元素插入到指定索引處的列表中,程式碼如下 −
範例
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ string[] strArr = { "John", "Tom", "Kevin", "Mark", "Gary" }; List<string> list = new List<string>(strArr); Console.WriteLine("Elements in a List..."); foreach(string str in list){ Console.WriteLine(str); } strArr = new string[] { "Demo", "Text" }; Console.WriteLine("Inserted new elements in a range..."); list.InsertRange(3, strArr); foreach(string res in list){ Console.WriteLine(res); } } }
輸出
這將產生以下輸出 −
Elements in a List... John Tom Kevin Mark Gary Inserted new elements in a range... John Tom Kevin Demo Text Mark Gary
範例
現在讓我們看另一個示例 −
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ int[] intArr = { 10, 20, 30, 40, 50 }; List<int> list = new List<int>(intArr); Console.WriteLine("Elements in a List..."); foreach(int i in list){ Console.WriteLine(i); } intArr = new int[] { 300, 400, 500}; Console.WriteLine("Inserted new elements in a range..."); list.InsertRange(2, intArr); foreach(int res in list){ Console.WriteLine(res); } } }
輸出
這將產生以下輸出 −
Elements in a List... 10 20 30 40 50 Inserted new elements in a range... 10 20 300 400 500 30 40 50
