Comentarios. El método estático Equals (Object, Object) indica si dos objetos, objA y objB, son iguales. También permite probar objetos cuyo valor es NULL para determinar si son iguales. Compara objA y objB para la igualdad de la siguiente manera: Determina si los dos objetos representan la misma referencia de objeto.
It determines whether the two objects represent the same object reference. If they do, the method returns true. This test is equivalent to calling the ReferenceEquals method. In addition, if both objA and objB are null, the method returns true.
27 de sept. de 2008 · equals() means that the objects logically equal (say, from a business point of view). So if you are comparing instances of a user-defined class, you would generally need to use and define equals() if you want things like a Hashtable to work properly.
- == is the identity test. It will return true if the two objects being tested are in fact the same object. Equals() performs an equality test, and w...

7 de abr. de 2023 · The == (equality) and != (inequality) operators check if their operands are equal or not. Value types are equal when their contents are equal. Reference types are equal when the two variables refer to the same storage.
26 de jul. de 2022 · In C#, the equality operator == checks whether two operands are equal or not, and the Object.Equals() method checks whether the two object instances are equal or not. Internally, == is implemented as the operator overloading method, so the result depends on how that method is overloaded.
