在N列表中查找公共对象

我有N个"人物"清单.人们有2个属性:Id和Name.我想找到所有N个列表中包含的人员.我只想匹配Id.

以下是我的出发点:

List result = new List();

//I think I only need to find items in the first list that are in the others
foreach (People person in peoplesList.First()) {

    //then this is the start of iterating through the other full lists
    foreach (List list in peoplesList.Skip(1)) {

        //Do I even need this?

    }
}

我被困在试图把头包裹在中间部分.我只想要每个列表中的那些peoplesList.Skip(1).
