    It is always wiser not to use complex type marshaling between native code and managed code.
    In case of List, these type totally differ from each other as they have different memory layout for each item.

    So the best way is to write a utility function in a native dll that accepts array of string(char*) and manually build your native List and ultimately call the desired method. It is easy for your to create wrapper of that utility function.
