Dispose pattern. In object-oriented programming, the dispose pattern is a design pattern for resource management. In this pattern, a resource is held by an object, and released by calling a conventional method – usually called close, dispose, free, release depending on the language – which releases any resources the object is holding onto.
In computer science, garbage collection (GC) is a form of automatic memory management. [ 2 ] The garbage collector attempts to reclaim memory that was allocated by the program, but is no longer referenced; such memory is called garbage. Garbage collection was invented by American computer scientist John McCarthy around 1959 to simplify manual ...
JavaScript has a deprecated Object.observe function that was a more accurate implementation of the observer pattern. [7] This would fire events upon change to the observed object. Without the deprecated Object.observe function, the pattern may be implemented with more explicit code: [8]
Async/await. Appearance. In computer programming, the async/await pattern is a syntactic feature of many programming languages that allows an asynchronous, non-blocking function to be structured in a way similar to an ordinary synchronous function. It is semantically related to the concept of a coroutine and is often implemented using similar ...

C#(/ˌsiːˈʃɑːrp/see SHARP)[b]is a general-purposehigh-levelprogramming languagesupporting multiple paradigms. C# encompasses static typing,[16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic,[16]: 22 object-oriented(class-based), and component-orientedprogramming disciplines.
Destructor (computer programming) In object-oriented programming, a destructor (sometimes abbreviated dtor[1]) is a method which is invoked mechanically just before the memory of the object is released. [2] It can happen when its lifetime is bound to scope and the execution leaves the scope, when it is embedded in another object whose lifetime ...
C# implements closure blocks by means of the using statement. The using statement accepts an expression which results in an object implementing IDisposable, and the compiler generates code that guarantees the object's disposal when the scope of the using -statement is exited. The using statement is syntactic sugar.
