XML Query (Xpath)

Question

我正在尝试获取有关Spesific演员的所有详细信息，并且要找到这个Spesific Actors，我拥有的功能可以回收XMLDOC和2个字符串参数：名字和姓氏，以及在我的代码中在下面，我总是得到0个nodeeslements。有人可以告诉我我做错了什么吗？

 public XmlNodeList Query3(XmlDocument xmlDoc, String actorFirstName, String actorLastName)// returns all the awards of all TV-shows of an actor
        {
string s = "Netflix/movies/movie/actors/actor[first-name="+actorFirstName+"last-name="+actorLastName+"]";
            XmlNodeList xmlNodeList = xmlDoc.SelectNodes(s);
            foreach (XmlNode x1 in xmlNodeList)
            {
                Console.WriteLine(x1.InnerText);
            }
            return xmlNodeList;
}

xmldoc：
