The following code:
public __gc class MyClass
{
public:
void MyFunc (int __gc* number);
};
Generates the following metadata for C# when compiled in VC 2005 with the
/clr:oldsyntax switch in a DLL project:
public class MyClass
{
public MyClass();
public void MyFunc(ref int number);
}
I’d like to use C++/CLI’s new syntax and declare a “ref class”.
I could not find the appropriate CLI syntax for declaring a function
parameter, which will appear as “ref” in the metadata.
I tried using the “int^” definition but it’s not possible to call this
function from C# and pass it a variable by reference.
I also tried using the [System::Runtime ::InteropServic es::OutAttribut e] but
the function declaration in the metadata appears without the “out” for the
number param.
What’s the correct CLI syntax for defining a "ref"/"out" function parameter?
Thanks in advance. 5 2680
this is the C# newsgroup and thus the wrong one for your question
but you use
int% number
for a ref parameter and
[Out]int% number
for a out parameter
where Out is System::Runtime ::InteropServic es::OutAttribut e

Have you tried applying the in and out attributes to get a ref?

If not that, try:
public __gc class MyClass
{
public:
void MyFunc (int __gc*& number);
};

Dear Simon,
Sorry for the misplacement.
The % operator solved my problem.
Thanks a bunch!

Hi,
I need to pass a pointer-to-member-function as a parameter to a function
which takes pointer-to-function as an argument. Is there any way to do it
besides overloading the function?
Here is a small program I wrote to check if I could get the address of the
function from the member-function-pointer, so that I could pass it to the
function as a normal function-pointer.

Declaring the function extern "C" fails, because linkage declarations

Hello,
I'm starting to investigate cs, managed c++ and interoperating with a very
large unmanaged code base. We are going to use Windows Forms (written in

Hi,
I have an unmanaged pointer to a class that I want to hold in a managed
class. I pass the pointer (from unmanaged code) in the constructor of the
managed class, and at that point it has value. It is stored in a member
variable in my managed class declared as MyObj __nogc* pMyObj. When I try to
retrieve it later, using a function declared as MyObj __nogc* GetObj, the
pointer has been corrupted and shows up as <undefined value> when...

We have a native class modeled after the System::Exception class, and all

quite simple: just Description and InnerException public members. One of
