ConsoleKeyInfo.Equals 메서드

정의

개체나 지정된 ConsoleKeyInfo 개체가 현재 ConsoleKeyInfo 개체와 같은지 여부를 나타내는 값을 가져옵니다.Gets a value indicating whether an object or specified ConsoleKeyInfo object is equal to the current ConsoleKeyInfo object.

Equals(ConsoleKeyInfo)

지정한 ConsoleKeyInfo 개체가 현재 ConsoleKeyInfo 개체와 같은지 여부를 나타내는 값을 가져옵니다.Gets a value indicating whether the specified ConsoleKeyInfo object is equal to the current ConsoleKeyInfo object.

Equals(Object)

지정한 개체가 현재 ConsoleKeyInfo 개체와 같은지 여부를 나타내는 값을 가져옵니다.Gets a value indicating whether the specified object is equal to the current ConsoleKeyInfo object.

Equals(ConsoleKeyInfo)

지정한 ConsoleKeyInfo 개체가 현재 ConsoleKeyInfo 개체와 같은지 여부를 나타내는 값을 가져옵니다.Gets a value indicating whether the specified ConsoleKeyInfo object is equal to the current ConsoleKeyInfo object.

public:
 bool Equals(ConsoleKeyInfo obj);
public bool Equals (ConsoleKeyInfo obj);
override this.Equals : ConsoleKeyInfo -> bool
Public Function Equals (obj As ConsoleKeyInfo) As Boolean

매개 변수

obj
ConsoleKeyInfo

현재 ConsoleKeyInfo 개체와 비교할 개체입니다.An object to compare to the current ConsoleKeyInfo object.

반환

true이 현재 obj 개체와 같으면 ConsoleKeyInfo이고, 그렇지 않으면 false입니다.true if obj is equal to the current ConsoleKeyInfo object; otherwise, false.

설명

해당 하는 KeyChar, KeyModifiers 속성이 같으면 두 ConsoleKeyInfo 개체가 같습니다.Two ConsoleKeyInfo objects are equal if their corresponding KeyChar, Key, and Modifiers properties are equal.

Equals 메서드는 obj를 개체로 변환할 필요가 없기 때문에 ConsoleKeyInfo.Equals(Object) 메서드보다 약간 더 잘 수행 됩니다.The Equals method performs slightly better than the ConsoleKeyInfo.Equals(Object) method because it does not have to convert obj to an object.

Equals(Object)

지정한 개체가 현재 ConsoleKeyInfo 개체와 같은지 여부를 나타내는 값을 가져옵니다.Gets a value indicating whether the specified object is equal to the current ConsoleKeyInfo object.

public:
 override bool Equals(System::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 ConsoleKeyInfo 개체와 비교할 개체입니다.An object to compare to the current ConsoleKeyInfo object.

반환

truevalue 개체이고 현재 ConsoleKeyInfo 개체와 같으면 ConsoleKeyInfo이고, 그러지 않으면 false입니다.true if value is a ConsoleKeyInfo object and is equal to the current ConsoleKeyInfo object; otherwise, false.
