In C#, apart from the distinction between value types and reference types, there is also a separate concept called reference variables. [3] A reference variable, once declared and bound, behaves as an alias of the original variable, but it can also be rebounded to another variable by using the reference assignment operator = ref. The variable ...
In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.An object referenced only by weak references – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable and ...
Boxing is the operation of converting a value of a value type into a value of a corresponding reference type. [15] Boxing in C# is implicit. Unboxing is the operation of converting a value of a reference type (previously boxed) into a value of a value type. [15] Unboxing in C# requires an explicit type cast. Example:
A reference is an abstract data type and may be implemented in many ways. Typically, a reference refers to data stored in memory on a given system, and its internal value is the memory address of the data, i.e. a reference is implemented as a pointer. For this reason a reference is often said to "point to" the data.
The type of a reference type can be determined from values of self-describing types. Self-describing types are further split into arrays and class types. The class types are user-defined classes, boxed value types, and delegates. The following example written in Visual Basic .NET shows the difference between reference types and value types:
Microsoft has developed open-source reference C# compilers and tools. The first compiler, Roslyn , compiles into intermediate language (IL), and the second one, RyuJIT, [ 119 ] is a JIT (just-in-time) compiler, which is dynamic and does on-the-fly optimization and compiles the IL into native code for the front-end of the CPU. [ 120 ]
Friend vs internal - access modifiers allowing inter-class but not inter-assembly reference, except for friend assemblies; Me vs this - a self-reference to the current object instance; MustInherit vs abstract - prevents a class from being directly instantiated, and forces consumers to create object references to only derived classes ...
A reference table (or table of reference) may mean a set of references that an author may have cited or gained inspiration from whilst writing an article, similar to a bibliography. It can also mean an information table that is used as a quick and easy reference for things that are difficult to remember such as comparing imperial with metric ...
