ConsoleKeyInfo.Equals ConsoleKeyInfo.Equals ConsoleKeyInfo.Equals ConsoleKeyInfo.Equals Method

定義

オブジェクトまたは指定した ConsoleKeyInfo オブジェクトが、現在の ConsoleKeyInfo オブジェクトと等しいかどうかを示す値を取得します。Gets a value indicating whether an object or specified ConsoleKeyInfo object is equal to the current ConsoleKeyInfo object.

オーバーロード

Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo)

指定された ConsoleKeyInfo オブジェクトと現在の ConsoleKeyInfo オブジェクトが等しいかどうかを示す値を取得します。Gets a value indicating whether the specified ConsoleKeyInfo object is equal to the current ConsoleKeyInfo object.

Equals(Object) Equals(Object) Equals(Object) Equals(Object)

指定されたオブジェクトと現在の ConsoleKeyInfo オブジェクトが等しいかどうかを示す値を取得します。Gets a value indicating whether the specified object is equal to the current ConsoleKeyInfo object.

Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo) Equals(ConsoleKeyInfo)

指定された ConsoleKeyInfo オブジェクトと現在の ConsoleKeyInfo オブジェクトが等しいかどうかを示す値を取得します。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

パラメーター

obj
ConsoleKeyInfo ConsoleKeyInfo ConsoleKeyInfo ConsoleKeyInfo

現在の ConsoleKeyInfo オブジェクトと比較するオブジェクト。An object to compare to the current ConsoleKeyInfo object.

戻り値

obj が現在の ConsoleKeyInfo オブジェクトに等しい場合は true。それ以外の場合は falsetrue if obj is equal to the current ConsoleKeyInfo object; otherwise, false.

注釈

2 つConsoleKeyInfoオブジェクトが等しい場合はそれに対応するKeyCharKey、およびModifiersプロパティが等しい。Two ConsoleKeyInfo objects are equal if their corresponding KeyChar, Key, and Modifiers properties are equal.

Equalsメソッドを少し実行よりも優れています、ConsoleKeyInfo.Equals(Object)メソッドに変換することはありませんのでobjオブジェクトにします。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) Equals(Object) Equals(Object) Equals(Object)

指定されたオブジェクトと現在の ConsoleKeyInfo オブジェクトが等しいかどうかを示す値を取得します。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

パラメーター

value
Object Object Object Object

現在の ConsoleKeyInfo オブジェクトと比較するオブジェクト。An object to compare to the current ConsoleKeyInfo object.

戻り値

valueConsoleKeyInfo オブジェクトで、現在の ConsoleKeyInfo オブジェクトと等しい場合は true。それ以外の場合は falsetrue if value is a ConsoleKeyInfo object and is equal to the current ConsoleKeyInfo object; otherwise, false.
