Community Goodies: Resource Index for Language Features of C++/CLI
| SUMMARY | C++/CLI is a self-contained, component-based dynamic programming language that, like C# or Java, is derived from C++; it is a binding of C++ to Microsoft’s .NET programming environment. This article is to give you a brief introduction of the language features of C++/CLI. |
| CLR Data Types | CLR types are prefixed with an adjective that describes what sort of type it is. The following are examples of CLR data type declarations in C++/CLI.
ref class RefClass{...}; ref struct RefClass{...};
value class ValClass{...}; value struct ValClass{...};
interface class IType{...}; interface struct IType{...};
enum class Day{...}; enum struct Day{...};
property int Property_Block { int get(); void set(int value) { MyInt = value; } }
public event delegate ^ event_name; For more information about the CLR Data types used in C++/CLI, see: Classes and Structs (Managed) https://msdn.microsoft.com/en-us/library/6w96b5h7.aspx Interface class https://msdn.microsoft.com/en-us/library/737cydt1.aspx enum class https://msdn.microsoft.com/en-us/library/a6cskb49.aspx Properties https://msdn.microsoft.com/en-us/library/es7h5kch.aspx Delegates: https://msdn.microsoft.com/en-us/library/3z2x4f55.aspx Events: |
| Override Specifiers | The following keywords can be used to qualify override behavior for derivation. Abstract (https://msdn.microsoft.com/en-us/library/b0z6b513.aspx ), New (https://msdn.microsoft.com/en-us/library/86hbff6c.aspx ), Override (https://msdn.microsoft.com/en-us/library/41w3sh1c.aspx ), Sealed (https://msdn.microsoft.com/en-us/library/0w2w91tf.aspx ) |
| New keywords | gcnew https://msdn.microsoft.com/en-us/library/te3ecsc8%28v=VS.100%29.aspx for each, in https://msdn.microsoft.com/en-us/library/ms177202%28v=VS.100%29.aspx initonly https://msdn.microsoft.com/en-us/library/4d8xah36.aspx literal https://msdn.microsoft.com/en-us/library/5yzft952.aspx nullptr |
| Generics | Generics are parameterized types supported by the common language runtime. A parameterized type is a type that is defined with an unknown type parameter that is specified when the generic is used. For more information, see |
| Operators | Two operators have been added to Visual C++ to support garbage-collected programming. ^ (Handle to Object on Managed Heap) https://msdn.microsoft.com/en-us/library/yk97tc08.aspx % (Tracking Reference) |
| Exception Handling | You can use both structured exception handling (SEH) and C++ exception handling under /clr. Under /clr, you can also handle CLR exceptions. A CLR exception is any exception thrown by a managed type. For more information, see |
| Type Forwarding | Type forwarding allows you to move a type from one assembly (assembly A) into another assembly (assembly B), such that, it is not necessary to recompile clients that consume assembly A. For more information, see https://msdn.microsoft.com/en-us/library/ms177220%28v=VS.100%29.aspx |
| User-Defined Attributes | You can define a custom attribute by defining a type and making Attribute a base class for the type and optionally applying the AttributeUsageAttribute attribute. For more information, see https://msdn.microsoft.com/en-us/library/yd21828z%28v=VS.100%29.aspx |
| Implicit Boxing | The Visual C++ compiler now boxes value types to Object. For more information, see https://msdn.microsoft.com/en-us/library/c53ss7ze%28v=VS.100%29.aspx |
| XML Documentation | In Visual C++, you can add comments to your source code that will be processed to an .xml file. For more information, see https://msdn.microsoft.com/en-us/library/ms177226%28v=VS.100%29.aspx You can learn more about the language features for C++/CLI from the following document: |
