Type.GetHashCode 메서드
해당 인스턴스에 대한 해시 코드를 반환합니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Overrides Function GetHashCode As Integer
‘사용 방법
Dim instance As Type
Dim returnValue As Integer
returnValue = instance.GetHashCode
public override int GetHashCode ()
public:
virtual int GetHashCode () override
public int GetHashCode ()
public override function GetHashCode () : int
반환 값
이 인스턴스의 해시 코드가 들어 있는 Int32입니다.
설명
이 메서드는 Object.GetHashCode를 재정의합니다.
예제
다음 예제에서는 System.Windows.Forms.Button의 해시 코드를 표시합니다.
