지정한 Object이(가) 현재 UnicodeEncoding 개체와 같은지 여부를 확인합니다.

public:
 override bool Equals(System::Object ^ value);

public override bool Equals (object value);

public override bool Equals (object? value);

override this.Equals : obj -> bool

Public Overrides Function Equals (value As Object) As Boolean

매개 변수

value

Object

현재 개체와 비교할 개체입니다.

반환

Boolean

value가 UnicodeEncoding 인스턴스이고 현재 개체와 같으면 true이고, 그렇지 않으면 false입니다.

예제

다음 예제에서는 메서드를 사용하여 현재 UnicodeEncoding 개체가 Equals 다른 UnicodeEncoding 개체와 같은지 여부를 테스트하는 방법을 보여 줍니다. 5개의 UnicodeEncoding 개체가 만들어지고 비교되고 비교 결과가 표시됩니다.

설명

다음 조건이 모두 true이면 두 UnicodeEncoding 개체가 같은 것으로 간주됩니다.

• 두 개체 모두 동일한 바이트 순서(little-endian 또는 big-endian)를 사용합니다.

• 두 개체 모두 바이트 순서 표시를 제공하거나 둘 다 제공하지 않습니다.

• 두 개체 모두 동일한 인코더 대체를 사용합니다.

• 두 개체 모두 동일한 디코더 대체를 사용합니다.

추가 정보

• UnicodeEncoding()
• Equals(Object)
