Explanation

In the above program, we created a class Demo that contains the Main() method. In the Main() method we created a list of employees with fields ID, Name, Salary, and Department.

var result = employees.Where(emp=>emp.Department=="ABC").OrderBy(sal => sal.Salary);

In the above code, we sorted a list of employees based on salary using OrderBy() and checked the department using Where() method.

Console.WriteLine("ID  Name  Salary  Department");
Console.WriteLine("============================");
foreach (Employee emp in result)
{
    Console.WriteLine(emp.ToString());
}
Console.WriteLine("============================");

In the above code, we accessed the employee detail one by one and print on the console screen.
