HashSet<T>.SymmetricExceptWith(IEnumerable<T>) HashSet<T>.SymmetricExceptWith(IEnumerable<T>) HashSet<T>.SymmetricExceptWith(IEnumerable<T>) HashSet<T>.SymmetricExceptWith(IEnumerable<T>) Method

정의

현재 HashSet<T> 개체를 수정하여 해당 개체와 지정된 컬렉션 중 하나에만 있는 요소만 포함합니다.Modifies the current HashSet<T> object to contain only elements that are present either in that object or in the specified collection, but not both.

예제

다음 예제에서는 두 개의 HashSet<T> 겹치는 데이터 집합을 사용 하는 컬렉션입니다.The following example creates two HashSet<T> collections with overlapping sets of data. 값은 낮은 값을 포함 하는 집합은 다음 수정 하 여를 SymmetricExceptWith 메서드를 두 집합 모두에 존재 하지 않는 값만 포함 합니다.The set that contains the lower values is then modified, using the SymmetricExceptWith method, to contain only the values that are not present in both sets.

static void Main()
{
    HashSet<int> lowNumbers = new HashSet<int>();
    HashSet<int> highNumbers = new HashSet<int>();

    for (int i = 0; i < 6; i++)
    {
        lowNumbers.Add(i);
    }

    for (int i = 3; i < 10; i++)
    {
        highNumbers.Add(i);
    }

    Console.Write("lowNumbers contains {0} elements: ", lowNumbers.Count);
    DisplaySet(lowNumbers);

    Console.Write("highNumbers contains {0} elements: ", highNumbers.Count);
    DisplaySet(highNumbers);

    Console.WriteLine("lowNumbers SymmetricExceptWith highNumbers...");
    lowNumbers.SymmetricExceptWith(highNumbers);

    Console.Write("lowNumbers contains {0} elements: ", lowNumbers.Count);
    DisplaySet(lowNumbers);



}
/* This example provides output similar to the following:
 * lowNumbers contains 6 elements: { 0 1 2 3 4 5 }
 * highNumbers contains 7 elements: { 3 4 5 6 7 8 9 }
 * lowNumbers SymmetricExceptWith highNumbers...
 * lowNumbers contains 7 elements: { 0 1 2 8 7 6 9 }

    Next i

    For i As Integer = 3 To 9
        highNumbers.Add(i)
    Next i

설명

경우는 other 매개 변수는를 HashSet<T> 현재 같은 같음 비교자를 사용 하 여 컬렉션 HashSet<T> 개체를이 메서드는 O (n) 작업입니다.If the other parameter is a HashSet<T> collection with the same equality comparer as the current HashSet<T> object, this method is an O(n) operation. 그렇지 않은 경우이 메서드는 O (n + m) 작업, 여기서 n 의 요소입니다 othermCount합니다.Otherwise, this method is an O(n + m) operation, where n is the number of elements in other and m is Count.
