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.
Microsoft added operator overloading to C# in 2001 and to Visual Basic .NET in 2003. Scala treats all operators as methods and thus allows operator overloading by proxy. In Raku, the definition of all operators is delegated to lexical functions, and so, using function definitions, operators can be overloaded or new operators added.
Any C# class can therefore intercept dynamic calls on its instances by implementing IDynamicMetaObjectProvider. In case of dynamic method and indexer calls, overload resolution happens at run-time according to the actual types of the values passed as arguments, but otherwise according to the usual C# overloading resolution rules.
When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order (i.e. the same signature), similar to Java, C# allows both a single method to cover all interfaces and if necessary specific methods for each interface. However, unlike Java, C# supports operator overloading. [90]
In object-oriented programming, an indexer allows instances of a particular class or struct to be indexed just like arrays. [1] It is a form of operator overloading . Implementation
Rank polymorphism is one of the defining features of the array programming languages, like APL. The essence of the rank-polymorphic programming model is implicitly treating all operations as aggregate operations, usable on arrays with arbitrarily many dimensions, [ 10 ] which is to say that rank polymorphism allows functions to be defined to ...
C# introduced support for dynamic multimethods in version 4 [8] (April 2010) using the 'dynamic' keyword. The following example demonstrates multimethods. Like many other statically-typed languages, C# also supports static method overloading. [9] Microsoft expects that developers will choose static typing over dynamic typing in most scenarios. [10]
In languages that support operator overloading by the programmer (such as C++) but have a limited set of operators, operator overloading is often used to define customized uses for operators. In the example IF ORDER_DATE > "12/31/2011" AND ORDER_DATE < "01/01/2013" THEN CONTINUE ELSE STOP, the operators are: > (greater than), AND and < (less than).
