试试这个：

  
pin_ptr < int > pp1 =
pnNum1 ;

  
pin_ptr < int > pp2 =
pnNum2 ;

  
NativeClassPtr->测试（pp1，pp2）;

 

I am use C++/CLI to wrapper native C++ class. I'm use wrapper class in C#.

One the methods of the C++ native class has the following declaration:
void Test(int *pnNum1, int *pnNum2);

The method Test of the C++/CLI managed class has the following declaration:

void Тest([Out]interior_ptr<int> pnNum1, [Out]interior_ptr<int> pnNum2); The parameter pnNum1 and pnNum2 passing by reference.

void ManageClass::Test[Out]interior_ptr<int> pnNum1, [Out]interior_ptr<int> pnNum2)

{

   NativeClassPtr->Test((int *)&pnNum1, (int *)&pnNum2);     //did not work!!!

}

How do I pass a parameter by reference of the method Test NativeClassPtr->Test?

I have to convert to interior_ptr to pin_ptr to native_ptr. How to do this without using variables(pin_ptr an native).

Try this:

   pin_ptr<int> pp1 = pnNum1;

   pin_ptr<int> pp2 = pnNum2;

   NativeClassPtr->Test( pp1, pp2 );
