Structs in C# very different from classes, see Structs vs Classes for more

Structs in C++ are identical to classes, EXCEPT that members are public by default. Other than that, a C++ struct can do everything a C++ class can do.

In C# you use structs to define value types (as opposed to reference types declared by classes).

In C++, a struct is the same thing as a class with a default accessibility level of public.

So the question should be: are structs in C# different from classes in C++ and, yes, they are: You cannot derive from C# structs, you cannot have virtual functions, you cannot define default constructors, you don't have destructors etc.

A C# struct is managed code, which will be freed by the C# garbage when nobody refers to it anymore. Its destructor is called whenever the garbage collector decides to clean it up.

A C++ struct is an unmanaged object, which you have to clean up yourself. It's destructor is predictably called when you delete it, or it goes out of scope.

Are you trying to interoperate between managed C++ and C#? If so, there are extensions to C++ to allow this: see link

Yes.

structs in c# are plain old, by value, data types (as opposed to classes that are by reference and have ll the OO stuff)

structs in c++ are just class that are public by default.
