  2. C Sharp 2.0 - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_2.0

    As a precursor to the lambda functions introduced in C# 3.0, C#2.0 added anonymous delegates. These provide closure-like functionality to C#. [3] Code inside the body of an anonymous delegate has full read/write access to local variables, method parameters, and class members in scope of the delegate, excepting out and ref parameters.

  3. Objective-C - Wikipedia

    en.wikipedia.org/wiki/Objective-C

    A category has full access to all of the instance variables within the class, including private variables. If a category declares a method with the same method signature as an existing method in a class, the category's method is adopted. Thus categories can not only add methods to a class, but also replace existing methods.

  4. C Sharp (programming language) - Wikipedia

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

    When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order (i.e. the same signature), similar to Java, C# allows both a single method to cover all interfaces and if necessary specific methods for each interface. C# also offers function overloading (a.k.a. ad-hoc ...

  5. Class variable - Wikipedia

    en.wikipedia.org/wiki/Class_variable

    A class variable is not an instance variable. It is a special type of class attribute (or class property, field, or data member). The same dichotomy between instance and class members applies to methods ("member functions") as well; a class may have both instance methods and class methods.

  6. Plain old CLR object - Wikipedia

    en.wikipedia.org/wiki/Plain_Old_CLR_Object

    Plain Old CLR Object is a play on the term plain old Java object from the Java EE programming world, which was coined by Martin Fowler in 2000. [2] POCO is often expanded to plain old C# object, though POCOs can be created with any language targeting the CLR.

  7. Generic programming - Wikipedia

    en.wikipedia.org/wiki/Generic_programming

    Arrays and structs can be viewed as predefined generic types. Every usage of an array or struct type instantiates a new concrete type, or reuses a previous instantiated type. Array element types and struct element types are parameterized types, which are used to instantiate the corresponding generic type.

  8. Variable shadowing - Wikipedia

    en.wikipedia.org/wiki/Variable_shadowing

    In computer programming, variable shadowing occurs when a variable declared within a certain scope (decision block, method, or inner class) has the same name as a variable declared in an outer scope. At the level of identifiers (names, rather than variables), this is known as name masking .

  9. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    In general, there are two types of string datatypes: fixed-length strings, which have a fixed maximum length to be determined at compile time and which use the same amount of memory whether this maximum is needed or not, and variable-length strings, whose length is not arbitrarily fixed and which can use varying amounts of memory depending on ...
