The cast operator is not overloadable, but one can write a conversion operator method which lives in the target class. Conversion methods can define two varieties of operators, implicit and explicit conversion operators. The implicit operator will cast without specifying with the cast operator (()) and the explicit operator requires it to be used.
In computer science, type conversion, [1] [2] type casting, [1] [3] type coercion, [3] and type juggling [4] [5] are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string , and vice versa.
Java, Pascal, Ada, and C require variables to have a declared type, and support the use of explicit casts of arithmetic values to other arithmetic types. Java, C#, Ada, and Pascal are sometimes said to be more strongly typed than C, because C supports more kinds of implicit conversions, and allows pointer values to be explicitly cast while Java ...
Mono, a Microsoft-sponsored project provides an open-source C# compiler, a complete open-source implementation of the CLI (including the required framework libraries as they appear in the ECMA specification,) and a nearly complete implementation of the NET class libraries up to .NET Framework 3.5.
In class-based programming, downcasting, or type refinement, is the act of casting a base or parent class reference, to a more restricted derived class reference. [1] This is only allowable if the object is already an instance of the derived class, and so this conversion is inherently fallible.
If separate implementations are needed (because the methods serve separate purposes, or because return values differ between the interfaces) C#'s explicit interface implementation will solve the problem, though allowing different results for the same method, depending on the current cast of the object.
Shared memory: Multiple processes are given access to the same block of memory, which creates a shared buffer for the processes to communicate with each other. All POSIX systems, Windows Message passing: Allows multiple programs to communicate using message queues and/or non-OS managed channels. Commonly used in concurrency models.
.NET Compiler Platform, also known by its codename Roslyn, [2] is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft. [3] The project notably includes self-hosting versions of the C# and VB.NET compilers – compilers written in the languages themselves. The compilers are available ...
