Linq查詢與字符串值列表進行比較

Question

我需要比較並從字符串列表中獲取LINQ的匹配值。 看看我的代碼。

碼

Split = Id.Split(',');
List<string> uids = new List<string>(Split);
var model = (from xx in Db.ItemWeedLogs
                where xx.ItemNo == uids   
                // I need to pass a string list to extract the matching record.
                select xx).ToList();

Answer 1

嘗試這個 ：

var model = (from xx in Db.ItemWeedLogs
                     where uids.Contains(xx.ItemNo)
                     select xx).ToList();

Answer 2

嘗試：

where uid.contains(xx.ItemNo)

Answer 3

我認為這更加快速和清晰。

var model = Db.ItemWeedLogs
              .Join(Id.Split(','), di => di.ItemNo, si => si, (d, s) => new {d})
              .ToList();
