c# - 通过 linq 查询过滤组

Question

 var testingAll =          (from ac in metaData.AcTable
                            where ac.Call >= DateTime.Now.AddMonths(-2) && ac.Call  <= DateTime.Now 
                            group adminCall by ac.LanguageCode into acc
                            select new { lang = acc.Key, count = acc.Count() }).ToDictionary(x => x.lang, y => y.count).OrderByDescending(x => x.Key);

我可以在日期时间之后再次使用过滤器吗？

像这样:

var Today = testingAll.Where( /*x => x.Call >= DateTime.Now.AddDays(-2)*/) 

Answer 1

我想你想要类似的东西

var testingAll =          (from ac in metaData.AcTable
                            where ac.Call >= DateTime.Now.AddMonths(-2) && ac.Call  <= DateTime.Now 
                            group adminCall by adminCall.LanguageCode into ac
                            select ac

这应该返回一个集合，然后您可以在其中查询多次。
