EDDYKT asked
Last Modified: 2012-05-12
I add the COM object into my c# program.
The COM object is written as c++ and i have no control on this

One of the function is defined in c++ is
setVariable(int count, STRUCT *p);
where STRUCT is typedef to structure and allow to pass an array of the STRUCT *

However, when i import to my c# program,
The prototype is shown as
setVariable(System.Int32 count , ref STRUCT p);

In c#, i declare the
STRUCT [] p = new STRUCT[10];
int count = 10;

Here is my question:
How do i can pass the array to the function?
i tried
setVariable(count , ref p[0]);
but in c++, it only see the first one
