C# function with 'params' not working in managed C++?

[MuZZy]

Hi,

Maybe it's a known issue but i couldn't find any answer so far...

Consider this c# function:

// ----------------------------------
public int SumUp(params int[] iArgs)
{
int i = 0;
foreach (int iArg in iArgs)
i += iArg;
return i;
}
// ---------------------------------

So this function accepts variable number of arguments.
Now, i try to call it from a c++ project with 7 (for example) arguments and i get an error saying
that SumUp() doesn't expect 7 arguments. Basicly it doesn't work with any number of arguments...

I specifically created that helper c# project as i wanted to use functions with variable-number of
arguments in c++ and c++ (managed) itself doesn't support that. I tried v_list but it's not working
with managed c++.

Any solutions/workarounds?

I would really apreciate any ideas!
Thank you in advance,
Andrey

Muzzy... I answered in the mc++ newsgroup: for the C# dll method:

namespace ClassLibrary1
{
public class Class1
{
public int TestArgs(params int[] args) {
return args.Length;
}
}
}

You can do in MC++2.0

int CallVarArgs() {
array<int,1>^ ai= gcnew array<int,1>(3){1,2,3};
ClassLibrary1::Class1^ c= gcnew ClassLibrary1::Class1;
return c->TestArgs(ai);
}

Jeff

Strange, my compiler has no trouble _now_ with handling varargs in
MC++2.0 aka C++/CLI.
