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_2.cpp // compile with: /clr generic <typename T> ref class GenericType {}; ref class ReferenceType {}; value struct ValueType {}; int main() { GenericType<ReferenceType^> x; GenericType<ValueType> y; } Type Parameters Type parameters in a generic class are treat...
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...
In questo viene utilizzato l'assembly creato in C#.C++ Copia // consuming_generics_from_other_NET_languages_2.cpp // compile with: /clr #using <consuming_generics_from_other_NET_languages.dll> using namespace System; class NativeClass {}; ref class MgdClass {}; int main() { Circular...
This example consumes the assembly authored in C#. Code 复制 // consuming_generics_from_other_NET_languages_2.cpp // compile with: /clr #using <consuming_generics_from_other_NET_languages.dll> using namespace System; class NativeClass {}; ref class MgdClass {}; int main() { CircularLis...
Here's a C++ example with two mixin types: one that allows you to mix in the property of having a time stamp, and another that mixes in a serial number for each object instance: //: generics/Mixins.cpp #include <string> #include <ctime> ...

Using valuetypes as type parameters, it is possible to write efficient classes that do arithmetic operations on type parameters. The code is not as short as it would be in C++, but that is acceptable considering the large benefits of constrained type parameters. The thing to keep in mind is...
A worakround is to place in a form .cpp code following lines: #pragma alias "toupper" = "_toupper" #pragma alias "tolower" = "_tolower" #pragma alias "isupper" = "_isupper" #pragma alias "isalnum" = "_isalnum" #pragma alias "isalpha" = "_isalpha" #pragma alias "iscntrl" = "...
