1、Skip操作符
Skip操作符用于从输入序列中跳过指定数量的元素，返回由序列中剩余的元素所组成的新序列。
例如，
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace ConsoleApplication{ class Program { static void Main(string[] args) { List pList = new List(); People p1 = new People(1, "C", 4); People p2 = new People(1, "Java", 7); People p3 = new People(1, "Python", 11); People p4 = new People(1, "Linux", 15); pList.Add(p1); pList.Add(p2); pList.Add(p3); pList.Add(p4); IEnumerable newList = pList.Skip(2); //跳过前两个 foreach (var item in newList) { Console.WriteLine(item.Name); } Console.ReadKey(); } } public class People { public People(int id, string name, int age) { this.Id = id; this.Name = name; this.Age = age; } public int Id { get; set; } public string Name { get; set; } public int Age { get; set; } }} 2、SkipWhile操作符
SkipWhile操作符用于从输入序列中跳过满足一定条件指定数量的元素，与TakeWhile操作符类似。如果条件满足就一直跳过，直到不满足后 就取剩下的所有元素(后面的不会再判断)。
例如，
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace ConsoleApplication{ class Program { static void Main(string[] args) { List pList = new List(); People p1 = new People(1, "C", 6); People p2 = new People(1, "C#", 11); People p3 = new People(1, "Java", 8); People p4 = new People(1, "Python", 15); pList.Add(p1); pList.Add(p2); pList.Add(p3); pList.Add(p4); IEnumerable newList = pList.SkipWhile(p => p.Age < 11); foreach (var item in newList) { Console.WriteLine(item.Name); } Console.WriteLine(); IEnumerable newList1 = pList.SkipWhile((p, i) => p.Age<12 && i < 2); foreach (People p in newList1) { Console.WriteLine(p.Name); } Console.ReadKey(); } } public class People { public People(int id, string name, int age) { this.Id = id; this.Name = name; this.Age = age; } public int Id { get; set; } public string Name { get; set; } public int Age { get; set; } }}
