Collection의 지정된 인덱스에서 요소를 제거하려면 코드는 다음과 같습니다. -
예
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"); col.Add("Mark"); Console.WriteLine("Count of elements = "+ col.Count); Console.WriteLine("Iterating through the collection..."); var enumerator = col.GetEnumerator(); while (enumerator.MoveNext()) { Console.WriteLine(enumerator.Current); } col.RemoveAt(3); Console.WriteLine("Count of elements (updated) = "+ col.Count); Console.WriteLine("Iterating through the collection... (updated)"); enumerator = col.GetEnumerator(); while (enumerator.MoveNext()) { Console.WriteLine(enumerator.Current); } } }
출력
이것은 다음과 같은 출력을 생성합니다 -
Count of elements = 9 Iterating through the collection... Andy Kevin John Kevin Mary Katie Barry Nathan Mark Count of elements (updated) = 8 Iterating through the collection... (updated) Andy Kevin John Mary Katie Barry Nathan Mark
예
다른 예를 보겠습니다 -
using System; using System.Collections.ObjectModel; public class Demo { public static void Main() { Collection<string> col = new Collection<string>(); col.Add("One"); col.Add("Two"); col.Add("Three"); col.Add("Four"); col.Add("Five"); col.Add("Six"); Console.WriteLine("Count of elements = "+ col.Count); Console.WriteLine("Iterating through the collection..."); var enumerator = col.GetEnumerator(); while (enumerator.MoveNext()) { Console.WriteLine(enumerator.Current); } col.RemoveAt(1); col.RemoveAt(2); col.RemoveAt(3); Console.WriteLine("Count of elements (updated) = "+ col.Count); Console.WriteLine("Iterating through the collection... (updated)"); enumerator = col.GetEnumerator(); while (enumerator.MoveNext()) { Console.WriteLine(enumerator.Current); } } }
출력
이것은 다음과 같은 출력을 생성합니다 -
Count of elements = 6 Iterating through the collection... One Two Three Four Five Six Count of elements (updated) = 3 Iterating through the collection... (updated) One Three Five
