Linq跳过，接 [英] Linq skip, take

问题描述

我有一个包含4行的列表. 我需要获取第三行的值.

I have a list that has 4 rows. I need to get the value of the 3rd row.

    var result = (from rs in list
                  select rs).Skip(2).First();

我为什么要在此场景中使用Take(1)?

Is there a reason why I would want to use a Take(1) in this scenerio as I have seen used.

     var result = (from rs in list
                  select rs).Skip(2).Take(1);

推荐答案

Take(1)返回包含一个对象的IEnumerable<T>.
First()直接返回对象.

Take(1) returns an IEnumerable<T> containing one object.
First() returns the object directly.
