how to import STL vector to STL

[Builder]

How can I import the following COM interface to C#?

DECLARE_INTERFACE_(IVertices, IUnknown)
{
STDMETHOD(get_vertices) (THIS_ vector<POINT>& vertices) PURE;

STDMETHOD(set_vertices) (THIS_ vector<POINT> vertices) PURE;
};

Is it possible to import STL containers to C# at all?

Not that I know of. When crossing from COM to managed code you will
probably want to copy the elements from the STL container to (one or
more) arrays on the COM side, then copy from the arrays to
System.Collections (.*) on the managed side.

You'll have to tell .NET the layout of non-primitive array elements;
one way to do this is to define them in the IDL (inside the library)
so that the type library importer will automatically create managed
equivalents for you.

Builder... If you want to stick to STL you can convert a standard STL
Vector to a STL/CLI Vector in C++/CLI.

// test standard STL to STL/CLI
std::vector<std::string> stdVector;
stdVector.reserve(2);
stdVector.push_back("Hello");
stdVector.push_back("World");

vector<String^> cliVector;
cliVector.reserve(2);

std::vector<std::string>::iterator it3= stdVector.begin();
for(;it3 != stdVector.end();it3++) {
cliVector.push_back(Util::ConvertCS2MS(*it3));
}

vector<String^>::iterator it4= cliVector.begin();
for(;it4 != cliVector.end();it4++) {
Console::WriteLine(*it4);
}
