Call a c++ dll with stl container from .net -

having following function in native dll:

double sum (std::vector<double> vals) {     double s = 0.0;     (size_t = 0; < vals.size(); i++)     {         s += vals[i]     }     return s; } 

how can make callable .net (c#) ?

the problem is, there no pair vector<double>.

is possible alter c++ side make call possible? (without giving std c++ feature, including ability call other c++ libraries )

it not possible , should not done: do not pass stl classes on dll interface

however create c-function called c#. parameters pass c-array of doubles , second parameter - length of array. wrapper function convert std::vector , call original function.

double sumwrapper(double* pointertodoublearray, unsigned int numberofelements) {     //convert , call sum } 

this c-function can called c++ using custom marshalling described here. option simple wrapper generator (swig) auto - generate c-wrapper function , c# function calls c++ function in dll.

the other option have add c++/cli wrapper function can called c# , converts .net array of doubles stl vector.
