Re: Need help with Vector parameter when invoking C dll from C#

Hi Willy,
You're correct about this will not compile in C# correctly. I need help in
figuring out how to use and call this C++ function properly with the correct
paramenter type. The C++ function is
extern "C" DE_ERRORS __declspec(dllexport)EncodeAsnUser(Blob** ppBlob,
vector <CUserContextData>::iterator userDataIter)

I have the structure CUserContextData declare correctly in C# already. But
how do I use C# code to call this fucntion? I think the Blob** is declared
correctly but how do I declare a vector::iterator for the structure
CUserContextData as a parameter in C# to call this function? Thank you.

You can't call this function from C#, you can only pass an iterator from C++. What you could do is implement a function in a C++ wrapper that takes an array of type CUserContextData and convert this into a vector of type CUserContextData, then you need to declare a vector iterator for this vector and pass the iterator to the EncodeAsnUser function.

Willy.
