DUMPBIN utility mangled name output

Question

I am using DUMPBIN utility for getting mangled name from a c++ dll to use in a c# application . I am exposing a c++ class member function using __declspec(dllexport) and the output mangled name result is the folowing

?InitPort@CProtocolStack@@QAEEHEPAEKE@Z = ?InitPort@CProtocolStack@@QAEEHEPAEKE@Z (public: unsigned char __thiscall CProtocolStack::InitPort(int,unsigned char,unsigned char *,unsigned long,unsigned char))

Do I need to use the whole name in C# application while importing the same function ? If not, which part will be sufficient for importing?

It is an instance method of a C++ class. You cannot pinvoke them, a C++/CLI wrapper is required. — Hans Passant

You just need this bit:

?InitPort@CProtocolStack@@QAEEHEPAEKE@Z

Then you declare it something like:

[DllImport("your.dll",
    EntryPoint = "?InitPort@CProtocolStack@@QAEEHEPAEKE@Z",
    ExactSpelling = true)]
static extern byte CProtocolStack::InitPort( /* etc. */);
