linqとlambdaで2つのリストを比較します.1つは文字列で、もう1つはlongです

Question

私はここでたくさん読んでいますが、リストの1つが文字列リストなので、クエリの最後の部分で2つのリストを正しく比較する答えは見つかりませんでした長いリストlinqに精通している人にとっては簡単なはずです。

リスト1： JsonConvert.DeserializeObject<RelatedContacts>(json)?.list

Answer 1

使用.Contains：すべて一緒に

.Where(item => fileContactIds.Contains(item.ClientId)) 

（リファクタリングのビットを持つ）：[利用LINQのか、C＃への

var res = relatedContact.SelectMany(rc => rc.contacts.Select(pc => new 
      { 
       ClientId = pc.userclientcode, 
       Description = rc.clienttaxonomy, 
       Fullname = pc.fullname, 
       Email = pc.contactdetails != null && pc.contactdetails.Count >= 1 ? pc.contactdetails[0].contactdata : "", 
       Address = pc.contactdetails != null && pc.contactdetails.Count >= 2 ? pc.contactdetails[1].contactdata : "", 
       PhoneNumber = pc.contactdetails != null && pc.contactdetails.Count >= 3 ? pc.contactdetails[2].contactdata : "", 
      })) 
      .Where(el => fileContactIds.Contains(el.ClientId));
