Implementazioni

Commenti

Questo metodo implementa l' System.IEquatable<T> interfaccia ed esegue una leggermente migliore rispetto Equals a perché non è necessario convertire il value parametro in un oggetto.This method implements the System.IEquatable<T> interface, and performs slightly better than Equals because it does not have to convert the value parameter to an object.

Se value ha meno bit (è più piccolo) rispetto al tipo di istanza, alcuni linguaggi di programmazione eseguono una conversione implicita verso un tipo di conversione più ampio che trasforma il valore del parametro in un valore con più bit.If value has fewer bits (is narrower) than the instance type, some programming languages perform an implicit widening conversion that transforms the value of the parameter into a value with more bits.

Si supponga, ad esempio, che il Int32 tipo di istanza sia e Byteche il tipo di parametro sia.For example, suppose the instance type is Int32 and the parameter type is Byte. Il compilatore C# Microsoft genera istruzioni per rappresentare il valore del parametro come Int32 oggetto, quindi genera un Int32.CompareTo metodo per confrontare la rappresentazione dell' Int32 istanza e del parametro.The Microsoft C# compiler generates instructions to represent the value of the parameter as an Int32 object, then generates a Int32.CompareTo method to compare the Int32 instance and parameter representation.

Consultare la documentazione del linguaggio di programmazione per determinare se il compilatore esegue conversioni implicite verso un tipo di informazioni più ampio su tipi numerici.Consult your programming language's documentation to determine whether its compiler performs implicit widening conversions on numeric types.

Note per i chiamanti

La risoluzione dell'overload del compilatore può tenere conto di una differenza evidente nel comportamento Equals(Object) dei due overload del metodo.Compiler overload resolution may account for an apparent difference in the behavior of the two Equals(Object) method overloads. Se viene definita una obj conversione implicita tra l' Decimal argomento e un oggetto e l'argomento non Objectè tipizzato come, i compilatori possono eseguire una conversione Equals(Decimal) implicita e chiamare il metodo.If an implicit conversion between the obj argument and a Decimal is defined and the argument is not typed as an Object, compilers may perform an implicit conversion and call the Equals(Decimal) method. In caso contrario, chiamano Equals(Object) il metodo, che restituisce false sempre se obj il relativo argomento non Decimal è un valore.Otherwise, they call the Equals(Object) method, which always returns false if its obj argument is not a Decimal value. Nell'esempio seguente viene illustrata la differenza di comportamento tra i due overload del metodo.The following example illustrates the difference in behavior between the two method overloads. Nel caso di tutti i tipi integrali primitivi, inclusi i tipi signed e unsigned, il primo confronto true restituisce perché il compilatore esegue automaticamente una conversione più ampia e chiama Equals(Decimal) il metodo, mentre il secondo il confronto false restituisce perché il compilatore chiama Equals(Object) il metodo.In the case of all primitive integral types, including both signed and unsigned types, the first comparison returns true because the compiler automatically performs a widening conversion and calls the Equals(Decimal) method, whereas the second comparison returns false because the compiler calls the Equals(Object) method.
