两个for循环筛选

[wozaiztam]

        public class Result
        {
            public string Url { get; set; }
        }

        public class UnKeyDomain
        {
            public string domain { get; set; }
        }

            var resultList = new List<Result>();
            resultList.Add((new Result() { Url = "www.google.com" }));
            resultList.Add((new Result() { Url = "www.baidu.com" }));
            resultList.Add((new Result() { Url = "www.bing.com" }));
            resultList.Add((new Result() { Url = "www.yahoo.com" }));

            var unKeyDomainList = new List<UnKeyDomain>();
            unKeyDomainList.Add((new UnKeyDomain() { domain = "yahoo.com" }));

//我现在要在resultList 中排除掉含有unKeyDomainList 域名的数据，返回：
//   resultList.Add((new Result() { Url = "www.google.com" }));
//            resultList.Add((new Result() { Url = "www.baidu.com" }));
//            resultList.Add((new Result() { Url = "www.bing.com" }));

请问怎么做？

resultList = resultList.Where(s => !unKeyDomainList.Any(ukd => s.Url.Contains(ukd.domain))).ToList();

不好意思，unKeyDomainList不止一条数据，我少写了

[wozaiztam]

resultList.Where(i => !i.Url.Contains(unKeyDomainList[0].domain)).ToList();

这边也不止一条

[nanking小杆子]

var s2 = from p in resultList where !(unKeyDomainList.Select(r => r.domain).ToArray().Contains(p.Url)) select p; 没有4楼的好！
