        TotalSalary=employees.Aggregate<Employee, int>(0, (sum, e) => sum += e.Salary);

        Console.WriteLine("Total Salary : "+TotalSalary);
    }

Explanation:

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

TotalSalary=employees.Aggregate<Employee, int>(0, (sum, e) => sum += e.Salary);

In the above statement, we calculated the total of all employee's salaries using the Aggregate() method and then print the total of salary on the console screen.
