使用 LINQ 打印姓名最后一个字符为“n”的员工的 C# 程序

LINQ 被称为语言集成查询，它是在 .NET 3.5 中引入的。它使 .NET 语言能够生成查询以从数据源检索数据。它消除了编程语言和数据库之间的不匹配，并且无论使用哪种类型的数据源，用于创建查询的语法都是相同的。在本文中，我们将研究如何使用 LINQ 打印姓名最后一个字符为“n”的员工姓名列表。

例子：

Input : List of Employees:
       {{id = 101, name = "Sravan", age = 12},
        {id = 102, name = "deepu",  age = 15},
        {id = 103, name = "manoja", age = 13},
        {id = 104, name = "Sathwik", age = 12},
        {id = 105, name = "Saran",  age = 15}}
Output: {{id = 105, name = "sravan", age = 15},
        {id = 105, name = "Saran",  age = 15}}
   
Input: List of Employees:
      {{id = 102, name = "deepu",  age = 15},
       {id = 103, name = "manoja", age = 13}}
Output: No Output

方法：

To find the list of employees whose name ends with ‘n’ character follow the following steps:

Create a list of employees with four variables(Id, name, department, and team).
Iterate through the employee details and get the employee details by choosing employee name ends with ‘n’ using the following queries:

Now call the ToString() method.
Display the employee details.

编程需要懂一点英语

例子：

C#

IEnumerable Query = from emp in employees
                              where emp.name[emp.name.Length - 1] == 'n'
                              select emp;

输出：

// C# program to display the list of employees
// whose last character of the name is 'n' 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
  
// Create a class with four variables
// employee id, name, and department
class Employee{
      
int id;
string name;
string department;
  
// To string method
public override string ToString()
{
    return id + " " + name + " " + department;
}
  
// Driver code
static void Main(string[] args)
{
      
    // Create list of employees with 5 data
    List emp = new List()
    {
        new Employee{ id = 101, name = "Sravan", 
                      department = "Development" },
        new Employee{ id = 102, name = "deepu",  
                      department = "HR" },
        new Employee{ id = 103, name = "manoja", 
                      department = "Development" },
        new Employee{ id = 104, name = "Sathwik", 
                      department = "Development" },
        new Employee{ id = 105, name = "Saran", 
                      department = "HR" }
    };
      
    // Condition to get employee name ends with 'n'
    IEnumerable result = from e in emp
                                   where e.name[e.name.Length - 1] == 'n'
                                   select e;
  
    Console.WriteLine("ID  Name  Department");
    Console.WriteLine("++++++++++++++++++++");
      
    // Iterating the employee data to display 
    // By calling the to string method
    foreach (Employee x in result)
    {
        Console.WriteLine(x.ToString());
    }
}
}
