C# 程序使用 LINQ 根据工资降序排序员工列表，其部门是 XYZ

给定一个员工列表，现在我们按照薪水降序对列表进行排序，其部门为 XYZ。所以我们使用 LINQ 的 OrderByDescending() 方法和 Where() 方法。 OrderByDescending() 用于按降序对指定列表进行排序。为了解决给定的问题，我们使用以下 LINQ 查询：

var result_set = Geeks.Where(emp=>emp.Emp_Department==”XYZ”).OrderByDescending(sal => sal.Emp_Salary);

在这里，Where() 方法查找部门为“XYZ”的员工，OrderByDescending() 方法根据他们的薪水按降序对他们进行排序。

例子：

Input: {id = 202, Name = Mohit, Salary = 10000, Department = XYZ}
       {id = 204, Name = Sumit, Salary = 20000, Department = ABC}
       {id = 205, Name = Pritam, Salary = 80000, Department = ABC}
       {id = 206, Name = Poonam, Salary = 30000, Department = XYZ}
Output: {id = 206, Name = Poonam, Salary = 30000, Department = XYZ}
        {id = 202, Name = Mohit, Salary = 10000, Department = XYZ}

C#

// C# program to sort a list of employees based on
// salary in descending order and whose department is XYZ
using System;
using System.Linq;
using System.Collections.Generic;
 
class Geek{
     
int emp_id;
string Emp_Name;
int Emp_Salary;
string Emp_Department;
 
static void Main(string[] args)
{
     
    // List to store the details of employees
    List Geeks = new List()
    {
        new Geek{emp_id = 101, Emp_Name = "Amit",
                 Emp_Salary = 50000,Emp_Department = "XYZ"},
        new Geek{emp_id = 102, Emp_Name = "Poonam",
                 Emp_Salary = 65000,Emp_Department = "ABC"},
        new Geek{emp_id = 103, Emp_Name = "Priya",
                 Emp_Salary = 45000,Emp_Department = "ABC"},
        new Geek{emp_id = 104, Emp_Name = "Sita",
                 Emp_Salary = 20000,Emp_Department = "XYZ"},
        new Geek{emp_id = 105, Emp_Name = "kiran",
                 Emp_Salary = 70000,Emp_Department = "ABC"},
        new Geek{emp_id = 106, Emp_Name = "Sohan",
                 Emp_Salary = 40000,Emp_Department = "XYZ"},
    };
 
    // Using the where command we have selected the
    // geeks having XYZ department and then we have
    // sorted the data in descending order using
    // OrderByDescending() command
    var result_set = Geeks.Where(emp => emp.Emp_Department == "XYZ").OrderByDescending(
                                 sal => sal.Emp_Salary);
                                  
    // Display the results
    foreach (Geek emp in result_set)
    {
        Console.WriteLine(emp.emp_id + " " +
                          emp.Emp_Name + " " +
                          emp.Emp_Salary + " " +
                          emp.Emp_Department);
    }
}
}

输出：

101 Amit 50000 XYZ
106 Sohan 40000 XYZ
104 Sita 20000 XYZ
