What is the C++/CLI equivalent to C#'s default(T)?

Question

I\'m working with some C++/CLI code (new syntax) and am trying to declare a generic type and want to set a member variable to it\'s default.

In C#:

c         


        

Answer 1

But isn't the private member already initialized with the default constructor?

Answer 2

Interestingly enough the syntax makes it looks like this: T(). It does require the addition of a copy constructor.

generic<typename T> 
    public ref class Class 
{
public:
    Class() : member(T())  
    {
    } 

    Class(Class^ c)
    {
        member = c->member;
    }

private:
    T member;
};

Edit DOH This works too (been in C# land for so long I forgot that NULL and 0 are the same thing in C++, hence no need for different value and reference type default values):

generic<typename T> 
    public ref class Class 
{
public:
    Class() : member(0)  
    {
    } 

    Class(Class^ c)
    {
        member = c->member;
    }

private:
    T member;
};
