Metaprogramming by means of C# attributes is part on the language. Quite a few of such characteristics replicate the functionality of GCC's and VisualC++'s platform-dependent preprocessor directives. Methods and capabilities[edit]

The DotGNU project (now discontinued) also presented an open-resource C# compiler, a nearly entire implementation of your Widespread Language Infrastructure including the essential framework libraries as they appear within the ECMA specification, and subset of several of the remaining Microsoft proprietary .

The C# language would not allow for worldwide variables or features. All techniques and associates should be declared within just lessons. Static users of community classes can substitute for worldwide variables and capabilities.

The identify "C sharp" was inspired with the musical notation where by a pointy suggests which the penned note really should be made a semitone higher in pitch.[36]

Xamarin presents instruments to establish cross-System programs for prevalent cell and desktop functioning devices, using C# as a codebase and compiling to indigenous code.

This line writes the output. Console is usually a static course within the System namespace. It offers an interface into the regular enter, output, and mistake streams for console applications.

Portability is critical for source code and programmers, Primarily those by now aware of C and C++.

Unboxing may be the Procedure of changing a value of a reference type (Earlier boxed) right into a worth of a worth variety.[65] Unboxing in C# involves an specific kind cast. A boxed object of form T can only be unboxed to a T (or even a nullable T).[sixty six]

In C#, memory handle ideas can only be used in blocks specially marked as unsafe, and packages with unsafe code will need ideal permissions to run. Most item accessibility is finished through Protected item references, which normally possibly level to the "Reside" item or possess the properly-defined null price; it really is extremely hard to obtain a reference try here to a "lifeless" item (one that has been garbage collected), or into a random block of memory.

C# supports a rigid Boolean data form, bool. Statements that acquire disorders, for instance whilst and if, have to have an expression of a kind that implements the accurate operator, such as the Boolean form. While C++ also contains a Boolean form, it may be freely transformed to and from integers, and expressions like if(a) involve only that a is convertible to bool, letting a to get an int, or perhaps a pointer.

C# can make usage of reification to deliver "first-class" generic objects that can be used like another class, with code technology carried out at class-load time.[28]

This is analogous to the language identify of C++, wherever "++" suggests that a variable needs to be incremented by 1 after getting evaluated. The sharp symbol also resembles a ligature of four "+" symbols (in the two-by-two grid), further implying that the language can be an increment of C++.[37]

Boxing may be the operation of converting a worth-kind item right into a worth of a corresponding reference form.[sixty five] Boxing in C# is implicit.

C# has specific assist for covariance and contravariance in generic styles, not like C++ which has some degree of assistance for contravariance only through the semantics of return types on virtual methods.

An unsafe pointer can place to an instance of the 'unmanaged' worth form that does not have any references to garbage-collected objects, array, string, or perhaps a block of stack-allocated memory. Code that isn't marked as unsafe can however retail store and manipulate ideas in the Technique.IntPtr style, nevertheless it cannot dereference them.

In contrast to C++, C# does not aid numerous inheritance, Whilst a class can implement any range of interfaces. This was a find more information style and design final decision through the language's direct architect to avoid complication and simplify architectural needs all over CLI.

C# offers Learn More Here properties as syntactic sugar for a common pattern through which a pair of procedures, accessor (getter) and mutator (setter) encapsulate operations on just one attribute of a class. No redundant method signatures[definition necessary] to the getter/setter implementations want be composed, as well as the property might be accessed using attribute syntax rather than extra verbose system phone calls.
