C# has and allows pointers to selected types (some primitives, enums, strings, pointers, and even arrays and structs if they contain only types that can be pointed [14]) in unsafe context: methods and codeblock marked unsafe. These are syntactically the same as pointers in C and C++.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
The Default declaration makes a property an index and able to use the shorter syntax for collection retrievals like MyCollection(5). C# has a similar construct reusing the keyword this as the name of the property. Multiple indexers can be declared using keys of different types e.g. MyCollection(5) or MyCollection("Bob").
Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. [1] In C++, there are only three access modifiers. C# extends the number of them to six, [2] while Java has four access modifiers, but three keywords for this purpose. In Java, having no keyword before defaults to the package ...
Thanks to the hosting virtual machine, different languages that are compliant with the .NET Common Language Infrastructure (CLI) can operate on the same kind of data structures. These languages can therefore use the FCL and other .NET libraries that are also written in one of the CLI compliant languages.
These language extensions have initially been implemented in C# 3.0, [5]: 75 VB 9.0, F# [6] and Oxygene, with other languages like Nemerle having announced preliminary support. The language extensions include: [7] Query syntax: A language is free to choose a query syntax that it will recognize natively.
A test driver is a kind of wrapper function that exercises a code module, typically calling it repeatedly, with different settings or parameters, in order to rigorously pursue each possible path. It is not deliverable code, but it is not throwaway code either, being typically retained for use in regression testing. An interface adaptor is a ...
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.
