虽然这可能更适合联接，但是您可以使用以下方法:

While this is probably better suited to a join, you can use this:

List<Personnel> query = 
    (from p in this.Database.Personnels 
    where OrgIds.Contains(p.OrgID) select p).ToList();

这将转换为类似SQL的内容.

This will translate into SQL something like..

where OrgID in (1,2,...,n)
