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

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(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
