Gibt einen Wert zurück, der angibt, ob diese Instanz einem angegebenen Objekt entspricht.

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

public override bool Equals(object obj);

public override bool Equals(object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

Parameter

obj: Object

Ein Objekt, das mit dieser Instanz verglichen werden soll.

Gibt zurück

Boolean

true if obj is an instance of UInt32 and equals the value of this instance; otherwise, false.

Beispiele

Im folgenden Codebeispiel wird die Equals Methode veranschaulicht.

UInt32 myVariable1 = 20;
UInt32 myVariable2 = 20;

// Display the declaring type.
Console.WriteLine("\nType of 'myVariable1' is '{0}' and"+
     " value is :{1}",myVariable1.GetType(), myVariable1);
Console.WriteLine("Type of 'myVariable2' is '{0}' and"+
     " value is :{1}",myVariable2.GetType(), myVariable2);

// Compare 'myVariable1' instance with 'myVariable2' Object.
if( myVariable1.Equals( myVariable2 ) )
   Console.WriteLine( "\nStructures 'myVariable1' and "+
         "'myVariable2' are equal");
else
   Console.WriteLine( "\nStructures 'myVariable1' and "+
         "'myVariable2' are not equal");

let myVariable1 = 20u
let myVariable2 = 20u

// Display the declaring type.
printfn $"\nType of 'myVariable1' is '{myVariable1.GetType()}' and value is :{myVariable1}"
printfn $"Type of 'myVariable2' is '{myVariable2.GetType()}' and value is :{myVariable2}"

// Compare 'myVariable1' instance with 'myVariable2' Object.

    printfn $"\nStructures 'myVariable1' and 'myVariable2' are equal"
else
    printfn $"\nStructures 'myVariable1' and 'myVariable2' are not equal"

Dim myVariable1 As UInt32 = UInt32.Parse(20)
Dim myVariable2 As UInt32 = UInt32.Parse(20)

' Display the declaring type.

Hinweise für Aufrufer

Die Compilerüberladungsauflösung kann einen offensichtlichen Unterschied im Verhalten der beiden Equals(UInt32) Methodenüberladungen ausmachen. Wenn eine implizite Konvertierung zwischen dem obj Argument und einem UInt32 definiert ist und das Argument nicht als Typ Objecteingegeben wird, führen Compiler eine implizite Konvertierung durch und rufen die Equals(UInt32) Methode auf. Andernfalls rufen sie die Equals(Object) Methode auf, die immer zurückgegeben wird false , wenn das obj Argument kein UInt32 Wert ist. Das folgende Beispiel veranschaulicht den Unterschied im Verhalten zwischen den beiden Methodenüberladungen. Byte Bei und UInt16 werten gibt der erste Vergleich zurücktrue, da der Compiler automatisch eine Erweiterungskonvertierung durchführt und die Equals(UInt32) Methode aufruft, während der zweite Vergleich zurückgegeben wirdfalse, da der Compiler die Equals(Object) Methode aufruft.

 virtual bool Equals(System::UInt32 obj);

public bool Equals(uint obj);

override this.Equals : uint32 -> bool

Public Function Equals (obj As UInteger) As Boolean

Parameter

obj: UInt32

Ein Wert, der mit dieser Instanz verglichen werden soll.

Gibt zurück

Boolean

true if obj has the same value as this instance; otherwise, false.

Implementiert

Equals(T)

Hinweise

Diese Methode implementiert die System.IEquatable<T> Schnittstelle und führt etwas besser aus als die Equals(Object) Methode, da der obj Parameter nicht in ein Objekt konvertiert werden muss.
