筛选包含其他列表的列表

我想你需要这样的东西:

var results = list.Where(i => i.Names
                               .Any(name => filterNameList.Contains(name)));

您可以通过查看两个名称集的交集来解决此问题。

var filteredResult = result.Where(i => i.Names.Intersect(filter).Any());

HashSet<string> hashedFilter = new HashSet<string>(filterByNames);

var results = result
  .Where(x => x.Names
    .Any(name => hashedFilter.Contains(name))
  );
