c# - 我应该如何将此源更改为 LINQ？

Question

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);
    }
}

我应该如何将此源更改为 linq？

Answer 1

var resultList = moveList.SelectMany(m => sightList.Where( s => comparer
                                       .Equals((Vector3)s.position, m)).ToList();
