  4. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    Without named parameters, optional parameters can only appear at the end of the parameter list, since there is no other way to determine which values have been omitted. In languages that support named optional parameters, however, programs may supply any subset of the available parameters, and the names are used to determine which values have ...

    C# also offers function overloading (a.k.a. ad-hoc-polymorphism). [91] Since version 2.0, C# offers parametric polymorphism, i.e. classes with arbitrary or constrained type parameters, e.g. List<T>, a variable-sized array which only can contain elements of type T.

    They often begin with "Usage:" , the command, followed by a list of arguments. To indicate optional arguments, square brackets are commonly used, and can also be used to group parameters that must be specified together.

    An output parameter, also known as an out parameter or return parameter, is a parameter used for output, rather than the more usual use for input. Using call by reference parameters, or call by value parameters where the value is a reference, as output parameters is an idiom in some languages, notably C and C++, [ b ] while other languages have ...

    Property methods may take parameters; Properties can be passed to methods with ByRef parameters (ref parameters in C#). In C# you have to write three additional instructions: Declare a variable, copy the property value into the variable and copy the variable back to the property after the method call. Enums can be defined inside interfaces

    C# has a static class syntax (not to be confused with static inner classes in Java), which restricts a class to only contain static methods. C# 3.0 introduces extension methods to allow users to statically add a method to a type (e.g., allowing foo.bar() where bar() can be an imported extension method working on the type of foo).
