Explanation

In the above program, we created an Employee class that contains data members ID, Name, Age, and Salary. Here we override the ToString() method to return Employee information. The Employee class also one more method is known as Main().

List<Employee> employees = new List<Employee>()
{
    new Employee {ID=101,   Name="Sumit"    ,Age=23, Salary=4000},
    new Employee {ID=102,   Name="Ram"    ,Age=24, Salary=6000},
    new Employee {ID=103,   Name="Ken"    ,Age=25, Salary=7000},
    new Employee {ID=104,   Name="Raman"    ,Age=26, Salary=9000},
};

In the Main() method, we created List collection for Employees, It contains information of 4 employees.

IEnumerable<Employee> Query =
    from emp in employees
    where emp.Name.Length<4
    select emp;

In the above code, we created a query to get list of employees whose name contains less than 4 characters. Then we printed the Employee detail using "foreach" loop on the console screen.
