对具有多个条件的IEnumerable对象进行运行时筛选

Question

我收集了IEnumerable<Person>

类型的PersonCollection

它包含：

• 名称
• 市
• 区
• 国家

还有一些收集，比如数组

Array CityList = {"Delhi","Goa",...}
Array CountryList = {"India","USA",...}
Array DistrictList = {"Acb","Xyz",...}

我想在

上应用过滤器

attribute City, Country & District 
of PersonCollection on the basic 
of CityList, CountryList & DistrictList.

说我有一个过滤器

Array CityList = {"Delhi",}
Array CountryList = {"USA","UK"}
Array DistrictList = {null}

然后我需要这些记录的过滤结果

City = Delhi
OR
Country = USA
OR 
Country = UK

---

获得所需结果的任何解决方案？

    DistrictList.Contains(p.District)
