c# - How should I change this source into LINQ? -

list<node> resultlist = new list<node>(); nodeequalitycomparer comparer = new nodeequalitycomparer();  foreach (vector3 move in movelist) {     foreach (node sight in sightlist)     {         if (comparer.equals((vector3)sight.position, move))             resultlist.add(sight);     } } 

how should change source linq?

var resultlist = movelist.selectmany(m => sightlist.where( s => comparer                                        .equals((vector3)s.position, m)).tolist();
