C# Neo4j APOC A*通过路径

我正在尝试使用APOC A*进行路由：

match(s:Station {Name: "A"}), (e:Station { Name: "B"})
CALL apoc.algo.aStar(s, e,'Road>' ,'Length','Lat','Lon') YIELD path, weight
RETURN path, weight LIMIT 1

如何指定过孔点？目前，我必须将整个路径分为块A->B、B->C、C->D等等

public class Station {

    public long Id {get;set;}

    public string Name {get;set;}

    public double Lat {get;set;}

    public double Lon {get;set;}

}

public class Road {

    public double Length {get;set;}

}

谢谢
