The most recent version is 8.0, which was released in 2019 alongside version 16.3. Contents.Design goals The Ecma standard lists these design goals for C#:. The language is intended to be a simple, modern, general-purpose, language. The language, and implementations thereof, should provide support for software engineering principles such as checking, array, detection of attempts to use, and automatic. The name 'C sharp' was inspired by the musical notation where a indicates that the written note should be made a higher in.This is similar to the language name of, where ' indicates that a variable should be incremented by 1 after being evaluated. See also:Some notable features of C# that distinguish it from C, C, and Java where noted, are:Portability By design, C# is the programming language that most directly reflects the underlying (CLI).

Most of its intrinsic types correspond to value-types implemented by the CLI framework. However, the language specification does not state the code generation requirements of the compiler: that is, it does not state that a C# compiler must target a Common Language Runtime, or generate (CIL), or generate any other specific format. Theoretically, a C# compiler could generate machine code like traditional compilers of C or.Typing C# supports strongly typed implicit variable declarations with the keyword var, and implicitly typed arrays with the keyword new followed by a collection initializer.C# supports a strict, bool. Statements that take conditions, such as while and if, require an expression of a type that implements the true operator, such as the Boolean type.

While C also has a Boolean type, it can be freely converted to and from integers, and expressions such as if(a) require only that a is convertible to bool, allowing a to be an int, or a pointer. C# disallows this 'integer meaning true or false' approach, on the grounds that forcing programmers to use expressions that return exactly bool can prevent certain types of programming mistakes such as if (a = b) (use of assignment = instead of equality ).C# is more than C. The only by default are those that are considered safe, such as widening of integers. This is enforced at compile-time, during, and, in some cases, at runtime. No implicit conversions occur between Booleans and integers, nor between enumeration members and integers (except for literal 0, which can be implicitly converted to any enumerated type). Any user-defined conversion must be explicitly marked as explicit or implicit, unlike C and conversion operators, which are both implicit by default.C# has explicit support for in generic types, unlike C which has some degree of support for contravariance simply through the semantics of return types on virtual methods.members are placed in their own.The C# language does not allow for global variables or functions.

All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions.Local variables cannot variables of the enclosing block, unlike C and C.Metaprogramming via C# attributes is part of the language. Many of these attributes duplicate the functionality of GCC's and VisualC's platform-dependent preprocessor directives.Methods and functions A method in C# is a member of a class that can be invoked as a function (a sequence of instructions), rather than the mere value-holding capability of a class property. As in other syntactically similar languages, such as C and, the signature of a method is a declaration comprising in order: any optional scope modifier keywords (such as private), the explicit specification of its return type (such as int, or the keyword void if no value is returned), the name of the method, and finally, a parenthesized sequence of comma-separated parameter specifications, each consisting of a parameter's type, its formal name and optionally, a default value to be used whenever none is provided. Int foo = 42; // Value type. Object bar = foo; // foo is boxed to bar. Int foo2 = ( int ) bar; // Unboxed back to value type.

Libraries The C# specification details a minimum set of types and class libraries that the compiler expects to have available. In practice, C# is most often used with some implementation of the (CLI), which is standardized as ECMA-335 Common Language Infrastructure (CLI).In addition to the standard CLI specifications, there are many commercial and community class libraries that build on top of the.NET framework libraries to provide additional functionality. Examples The following is a very simple C# program, a version of the classic ' example. Static void Main This declares the class member method where the program begins execution. The.NET runtime calls the Main method.

(Note: Main may also be called from elsewhere, like any other method, e.g. From another method of Program.) The makes the method accessible without an instance of Program. Each console application's Main entry point must be declared static.

Otherwise, the program would require an instance, but any instance would require a program. To avoid that irresolvable, C# compilers processing (like that above) report an error, if there is no static Main method.

The void keyword declares that Main has no. Hltagconverter 014 - full. Torgersen, Mads (October 27, 2008). Retrieved October 28, 2008. ^. November 13, 2019 – via GitHub. November 13, 2019 – via GitHub.

In the, the, the and however, remains the preferred scale for everyday temperature measurement. The degree Celsius (symbol: °C) can refer to a specific on the Celsius scale or a unit to indicate a difference between two temperatures or an.

It is named after the Swedish astronomer (1701–1744), who developed a similar temperature scale. Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps.From 1743, the Celsius scale is based on 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 pressure. Prior to 1743, the scale was also based on the boiling and melting points of water, but the values were reversed (i.e. The boiling point was at 0 degrees and the melting point was at 100 degrees). The 1743 scale reversal was proposed by.By international agreement, between 1954 and 2019 the unit degree Celsius and the Celsius scale were defined by and the of (VSMOW), a precisely defined water standard. This definition also precisely related the Celsius scale to the scale, which defines the of with symbol K.

Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 K (0.01 °C). This means that a temperature difference of one degree Celsius and that of one kelvin are exactly the same.On 20 May 2019, the kelvin was so that its value is now determined by the definition of the rather than being defined by the triple point of VSMOW. This means that the triple point is now a measured value, not a defined value.

The newly-defined exact value of the Boltzmann constant was selected so that the measured value of the VSMOW triple point is exactly the same as the older defined value to within the limits of accuracy of contemporary. The degree Celsius remains exactly equal to the kelvin, and 0 K remains exactly −273.15 °C.
