使用linq从列表中删除项目

如何使用linq从列表中删除项目?

How to remove item from list using linq ?.

我有一个项目列表，每个项目本身都有一个其他项目列表，如果其他项目包含任何已通过列表的项目，我想检查一下，因此应删除主要项目.请检查代码以获得更清晰的信息.

I have a list of items and each item it self having a list of other items now I want to chaeck if other items contains any items of passed list so main item should be remove. Please check code for more clarity.

public Class BaseItems
{
    public int ID { get; set; }
    public List<IAppointment> Appointmerts { get; set; }
}

Public DeleteApp(List<IAppointment> appointmentsToCheck)
{
   List<BaseItems> _lstBase ; // is having list of appointments

   //now I want to remove all items from _lstBase  which _lstBase.Appointmerts contains 
   any item of appointmentsToCheck (appointmentsToCheck item and BaseItems.Appointmerts 
   item is having a same reference)

   //_lstBase.RemoveAll(a => a.Appointmerts.Contains( //any item from appointmentsToCheck));

}
