Unlike theEqualsmethod and the equality operator, theReferenceEqualsmethod cannot be overridden. Because of this, if you want to test two object references for equality and you are unsure about the implementation of theEqualsmethod, you can call theReferenceEqualsmethod. ...
This method can be overridden by a derived class. For example, many of the base data types return true if both objects represent the same value; otherwise, false. This method only compares primitives and objects. It must be overridden to compare more complex structures, such as arrays of obj...
This method cannot be overridden. Note Starting with .NET Framework 2.0, this method can be used to access non-public members if the caller has been granted ReflectionPermission with the ReflectionPermissionFlag.RestrictedMemberAccess flag and if the grant set of the non-public members is restricted...
Static methods cannot be overridden because they exist per class. To protect other sensitive methods, or core methods, from being overridden, use the final modifier. In the example below, methodAtt is declared as final, and so it cannot be overridden in any class that extends Attribute....
Member '<classname>.<procedurename>' that matches this signature cannot be overridden because the class '<classname>' contains multiple members with this same name and signature: <signaturelist> Member '<interfacename>.<procedurename>' that matches this signature cannot be implemented because the ...
A method of a superclass that is overridden by a subclass but the signature of the overridden method is incompatible with that of the inherited one. These can be only checked by explicitly marking method override in the code. Python also has no standard mechanism by which to inherit docstrings...
The access specifier for an overriding method can allow more, but not less, access than the overridden method. For example, a protected instance method in the superclass can be made public, but not private, in the subclass. You will get a compile-time error if you attempt to change an ...
{ PartName ="cassette", PartId =1534});// Write out the parts in the list. This will call the overridden// ToString method in the Part class.Console.WriteLine("\nBefore sort:");foreach(Part aPartinparts) { Console.WriteLine(aPart); }// Call Sort on the list. This will use the/...
Dependency property metadata should be overridden before the property system uses the dependency property. This equates to the time that specific objects are created for the class that registers the dependency property. Calls to OverrideMetadata should only be performed within the static constructors of...
The version of the overridden instance method that gets invoked is the one in the subclass. The version of the hidden static method that gets invoked depends on whether it is invoked from the superclass or the subclass. Consider an example that contains two classes. The first isAnimal, which...
