In Xojo, the "Extends" keyword is used with global methods. In C#, they are implemented as static methods in static classes, with the first argument being of extended class and preceded by "this" keyword. In Java, extension methods are added via Manifold, a jar file added to the project's classpath.
This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.
Type inference – C# 3 with implicitly typed local variables var and C# 9 target-typed new expressions new List comprehension – C# 3 LINQ; Tuples – .NET Framework 4.0 but it becomes popular when C# 7.0 introduced a new tuple type with language support [104] Nested functions – C# 7.0 [104] Pattern matching – C# 7.0 [104]
JScript .NET is a .NET programming language developed by Microsoft.. The primary differences between JScript and JScript .NET can be summarized as follows: . Firstly, JScript is a scripting language, and as such programs (or more suggestively, scripts) can be executed without the need to compile the code first.
A list comprehension has the same syntactic components to represent generation of a list in order from an input list or iterator: A variable representing members of an input list. An input list (or iterator). An optional predicate expression. And an output expression producing members of the output list from members of the input iterable that ...
Compound File Binary Format, a container format defined by Microsoft COM. It can contain the equivalent of files and directories. It can contain the equivalent of files and directories. It is used by Windows Installer and for documents in older versions of Microsoft Office . [ 44 ]
In object-oriented languages, string functions are often implemented as properties and methods of string objects. In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions.
When lexical scoping is used to infer this, the use of this in code, while not illegal, may raise warning bells to a maintenance programmer, although there are still legitimate uses of this in this case, such as referring to instance variables hidden by local variables of the same name, or if the method wants to return a reference to the current object, i.e. this, itself.
