How to skip(m).take(n) from a List<T>?

c#linq

提问by Mike108

Given:

鉴于:

List<int> list = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

How do I implement the following code?

如何实现以下代码?

var list2 = list.skip(2).take(5);

采纳答案by Esteban Araya

Your sample code will work as long as you include System.Linqin your using statements (and fix your method names .Skip(2)and .Take(5)).

只要您包含System.Linq在 using 语句中(并修复您的方法名称.Skip(2).Take(5)),您的示例代码就会起作用。

The reason your code did not work out of the box is that .Skipand .Takeare extension methods (as opposed to methods defined in the List class) found in the 'System.Linq' namespace.

你的代码没有盒子的锻炼的原因是,.Skip.Take为扩展方法(而不是List类中定义的方法)在“System.Linq的”命名空间中。
