Object::Equals Method (Object, Object)
Determines whether the specified object instances are considered equal.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- objA
- Type: System::Object
The first object to compare.
- objB
- Type: System::Object
The second object to compare.
Return Value
Type: System::Booleantrue if the objects are considered equal; otherwise, false. If both objA and objB are nullptr, the method returns true.
The static Equals method indicates whether two objects, objA and objB, are equal. It also enables you to test objects whose value is nullptr for equality. It compares objA and objB for equality as follows:
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 nullptr, the method returns true.
It determines whether either objA or objB is nullptr. If so, it returns false.
If the two objects do not represent the same object reference and neither is nullptr, it calls objA.Equals(objB) and returns the result. This means that if objA overrides the Object::Equals(Object) method, this override is called.
The following example illustrates the Equals method and compares it with the ReferenceEquals method.
