지정된 인덱스의 Collection에 요소를 삽입하려면 코드는 다음과 같습니다. -
예시
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Laptop");
col.Add("Desktop");
col.Add("Notebook");
col.Add("Ultrabook");
col.Add("Tablet");
col.Add("Headphone");
col.Add("Speaker");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
Console.WriteLine("Element at index 3 = " + col[3]);
Console.WriteLine("Element at index 4 = " + col[4]);
col.Insert(5, "Alienware");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
} 출력
이것은 다음과 같은 출력을 생성합니다 -
Elements in Collection... Laptop Desktop Notebook Ultrabook Tablet Headphone Speaker Element at index 3 = Ultrabook Element at index 4 = Tablet Elements in Collection...UPDATED Laptop Desktop Notebook Ultrabook Tablet Alienware Headphone Speaker
예시
이제 다른 예를 살펴보겠습니다 -
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Andy");
col.Add("Kevin");
col.Add("John");
col.Add("Kevin");
col.Add("Mary");
col.Add("Katie");
col.Add("Barry");
col.Add("Nathan");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
col.Insert(3, "Jacob");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
} 출력
이렇게 하면 다음 출력이 생성됩니다 -
Elements in Collection... Andy Kevin John Kevin Mary Katie Barry Nathan Elements in Collection...UPDATED Andy Kevin John Jacob Kevin Mary Katie Barry Nathan
