本文概述
在LINQ中, OrderBy降序运算符用于按降序对项目的列表/集合进行排序。
LINQ OrderByDescending运算符的语法
LINQ中OrdrByDescending运算符用于按降序对项目/集合列表进行排序的语法为:
C#代码
var studentname = Objstudent.OrderByDescending(x => x.Name);
LINQ OrderByDescending运算符示例
以下是使用LINQ OrderByDescending排序运算符对项目/集合列表进行降序排序的示例:
C#代码
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
//create object of Student class and create a list of the student information
List<Student> Objstudent = new List<Student>()
{
new Student() { Name = "Akshay", Gender = "Male", Subjects = new List<string> { "Mathematics", "Physics" } }, new Student() { Name = "Vaishali", Gender = "Female", Subjects = new List<string> { "Computer", "Botany" } }, new Student() { Name = "Arpita", Gender = "FMale", Subjects = new List<string> { "Economics", "Operating System", "Java" } }, new Student() { Name = "Shubham", Gender = "Male", Subjects = new List<string> { "Account", "Social Studies", "Chemistry" } }, new Student() { Name = "Himanshu", Gender = "Male", Subjects = new List<string>{ "English", "Charted" } }
};
/*OrderByDescending() operator is used to print
the name of the student in the descending form*/
var studentname = Objstudent.OrderByDescending(x => x.Name);
//foreach loop is used to print the name of the student
foreach (var student in studentname)
{
Console.WriteLine(student.Name);
}
Console.ReadLine();
}
}
//create a class student
class Student
{
public string Name { get; set; }
public string Gender { get; set; }
public List<string>
Subjects { get; set; }
}
}
以下是上述代码按降序排列的结果:
