Hi ,
I am new to Managed c++ and C# .
I've to use unmanaged code in C# . For that I've written a managed
wrapper. I am passing a byte array to a function and updating that byte
array. And I've to use that in my C# code.
And the link
http://groups.google.co.in/group/mi...4+++managed+c++&rnum=3&hl=en#6a697b4b060b8f93
says that
"you dont need to declare it as a reference, since in Managed C++ you
pass
everything by reference by default."

So I've tried like foo(Byte byteBuffer __gc[]) in my MC++ code.

But when I get the value in my C# code it has not been updated.

Can any one know how to pass a byte array by reference ..

Thanks in advance....

RSL.

That should work as long as you only want to change the elements of
the existing array. If you want to return a new array, you need to
pass it by reference.

But when I get the value in my C# code it has not been updated.

Can you post more of your code? Perhaps the problem is elsewhere.
