Namespaces are heavily used in C# language. All .NET Framework classes are organized in namespaces, to be used more clearly and to avoid chaos. Furthermore, custom namespaces are extensively used by programmers, both to organize their work and to avoid naming collisions. When referencing a class, one should specify either its fully qualified ...
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 framework includes a large class library called Framework Class Library (FCL). 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 ...
Class members and the body of a method are examples of what can live inside these braces in various contexts. Inside of method bodies, braces can be used to create new scopes: void DoSomething () { int a ; { int b ; a = 1 ; } a = 2 ; b = 3 ; // Will fail because the variable is declared in an inner scope.
In practice, the available CLASS words would be a list of less than two dozen terms. CLASS words, typically positioned on the right (suffix), served much the same purpose as Hungarian notation prefixes. The purpose of CLASS words, in addition to consistency, was to specify to the programmer the data type of a particular data field. Prior to the ...
Additionally, in C# if a block consists of only a single statement, the braces may be omitted. C# is case sensitive while Visual Basic .NET is not. Thus in C# it is possible to have two variables with the same apparent name, for example variable1 and Variable1. Visual Studio will correct (make uniform) the case of variables as they are typed in ...
More specifically, the singleton pattern allows classes to: [2] Ensure they only have one instance; Provide easy access to that instance; Control their instantiation (for example, hiding the constructors of a class) The term comes from the mathematical concept of a singleton.
The Framework Class Library (FCL) is a component of Microsoft's .NET Framework, the first implementation of the Common Language Infrastructure (CLI). In much the same way as Common Language Runtime (CLR) implements the CLI Virtual Execution System (VES), the FCL implements the CLI foundational Standard Libraries .
