Generics typically refer to the use of templates to create code that works with various data types in a type-safe manner. Templates allow you to write generic functions or classes with placeholders for data types.
// generics_overview_3.cpp // compile with: /clr Copy interface class I { void f1(); void f2(); }; ref struct R : public I { virtual void f1() {} virtual void f2() {} virtual void f3() {} }; generic <typename T> where T : I void f(T t) { t->f1(); t->f2()...
In this section, find out which generic features both the Windows Runtime and the common language runtime support, and which ones only the common language runtime supports. You'll also find out how to author your own generic methods and types in C++/CLI, and how to use generic types ...
Templates specialized in two different assemblies with the same type arguments are considered by the runtime to be different types. Generics are generated as a single piece of executable code which is used for all reference type arguments (this is not true for value types, which have a unique...
