  2. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    Like C++, and unlike Java, C# programmers must use the scope modifier keyword virtual to allow methods to be overridden by subclasses. Unlike C++, you have to explicitly specify the keyword override when doing so. [83] This is supposed to avoid confusion between overriding and newly overloading a function (i.e. hiding the former implementation).

    C Sharp syntax. 5 languages ... unless it is a keyword; ... virtual - Specifies that a method or property declaration can be overridden by a derived class.

  4. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    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. This is done using the same signature of a property or method but adding the modifier new in front of it ...

  5. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    In computer programming, a virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding).

    C# is case sensitive and all C# keywords are in lower cases. Visual Basic and C# share most keywords, with the difference being that the default Visual Basic keywords are the capitalised versions of the C# keywords, e.g. Public vs public, If vs if. A few keywords have very different versions in Visual Basic and C#:

  7. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    Virtual functions allow a program to call methods that don't necessarily even exist at the moment the code is compiled. [citation needed] In C++, virtual methods are declared by prepending the virtual keyword to the function's declaration in the base class. This modifier is inherited by all implementations of that method in derived classes ...

  8. Virtual class - Wikipedia

    en.wikipedia.org/wiki/Virtual_class

    In object-oriented programming, a virtual base class is a nested inner class whose functions and member variables can be overridden and redefined by subclasses of an outer class. [1] Virtual classes are analogous to virtual functions. The run time type of a virtual class depends on the run time type of an object of the outer class.

  9. C Sharp 3.0 - Wikipedia

    The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5.It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime.
