This is a feature of C# 4.0 and .NET Framework 4.0. Type dynamic is a feature that enables dynamic runtime lookup to C# in a static manner. Dynamic denotes a variable with an object with a type that is resolved at runtime, as opposed to compile-time, as normally is done.
In C#, class methods, indexers, properties and events can all be overridden. Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method.
When we derive a class from this base class, we inherit all the member variables and member functions that were not overridden (no constructors or destructors). If the derived class calls an inherited function which then calls another member function, then that function will never call any derived or overridden member functions in the derived ...
For instance, in C#, the base method or property can only be overridden in a subclass if it is marked with the virtual, abstract, or override modifier, while in programming languages such as Java, different methods can be called to override other methods. [15] An alternative to overriding is hiding the inherited code.
C# provides default interface methods since version 8.0 which allows to define body to interface member. [ 8 ] [ 5 ] : 28–29 [ 9 ] : 38 [ 10 ] : 466–468 D provides an explicit "alias this" declaration within a type can forward into it every method and member of another contained type.
The Sun Microsystems Java compiler requires that a source file name must match the only public class inside it, while C# allows multiple public classes in the same file, and puts no restrictions on the file name. C# 2.0 and later allows splitting a class definition into several files by using the partial keyword in the source code. In Java, a ...
Single inheritance. In the case of single inheritance (or in a language with only single inheritance), if the vpointer is always the first element in d (as it is with many compilers), this reduces to the following pseudo-C++: (* ((*
Also, derived classes can override inherited methods if the language allows. Not all languages support multiple inheritance. For example, Java allows a class to implement multiple interfaces, but only inherit from one class. [22] If multiple inheritance is allowed, the hierarchy is a directed acyclic graph (or DAG for short), otherwise it is a ...
