Type.GetHashCode-Methode

Gibt den Hashcode für diese Instanz zurück.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Overrides Function GetHashCode As Integer
'Usage
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

Rückgabewert

Ein Int32 mit dem Hashcode für diese Instanz.

Hinweise

Diese Methode überschreibt Object.GetHashCode.

Beispiel

Im folgenden Beispiel wird der Hashcode von System.Windows.Forms.Button angezeigt.
