This article shows how to define and consume user-defined reference types and value types in C++/CLI. Object instantiation Reference (ref) types can only be instantiated on the managed heap, not on the stack or on the native heap. Value types can be instantiated on the stack or the managed...
For more information on static constructors, see How to: Define Static Constructors in a Class or Struct. Example 复制 // mcppv2_interface_class2.cpp // compile with: /clr using namespace System; interface struct MyInterface { static int i; static void Test() { Console::WriteLine(i)...

Define an empty constructor method that takes an rvalue reference to the class type as its parameter, as demonstrated in the following example: C++ MemoryBlock(MemoryBlock&& other) : _data(nullptr) , _length(0) { } In the move constructor, assign the class data members from the source obj...

How to compose delegates You can use the "-" operator to remove a component delegate from a composed delegate. 複製 // mcppv2_compose_delegates.cpp // compile with: /clr using namespace System; delegate void MyDelegate(String ^ s); ref class MyClass { public: static void Hello(String ...
NOTE If you need to define a special rule for an object file, put the rule for the object file just above the rule that builds the executable. If several executables use the same object file, put the object rule above all of the executable rules. 注意如果需要为对象文件定义特殊规则,请将...
