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

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.

public:
 void SymmetricExceptWith(System::Collections::Generic::IEnumerable<T> ^ other);
[System.Security.SecurityCritical]
public void SymmetricExceptWith (System.Collections.Generic.IEnumerable<T> other);
member this.SymmetricExceptWith : seq<'T> -> unit
Public Sub SymmetricExceptWith (other As IEnumerable(Of T))

매개 변수

예제

다음 예에서는 겹치는 데이터 집합을 사용 하 여 두 개의 HashSet<T> 컬렉션을 만듭니다.The following example creates two HashSet<T> collections with overlapping sets of data. 그런 다음 SymmetricExceptWith 메서드를 사용 하 여 하위 값을 포함 하는 집합을 수정 하 여 두 집합에 없는 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.

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);

void DisplaySet(HashSet<int> set)
{
    Console.Write("{");
    foreach (int i in set)
    {
        Console.Write(" {0}", i);
    }
    Console.WriteLine(" }");
}

/* 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 }

설명

other 매개 변수가 현재 HashSet<T> 개체와 동일한 같음 비교자를 사용 하는 HashSet<T> 컬렉션인 경우이 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 않으면이 메서드는 O (n + m) 작업입니다. 여기서 nother의 요소 수이 고 mCount입니다.Otherwise, this method is an O(n + m) operation, where n is the number of elements in other and m is Count.
