Language is C# (i've got some code but it seems to not runcorrectly, would love a new take)

Create an Employee class with five fields: first name, lastname, workID, yearStartedWked, and initSalary. It includesconstructor(s) and properties to initialize values for all fields.Create an interface, SalaryCalculate, class that includes twofunctions: first,CalcYearWorked() function, it takes one parameter(currentyear) and calculates the number of year the worker has beenworking. The second function, CalcCurSalary() function thatcalculates the current year salary. Create a Worker classes that isderived from Employee and SalaryCalculate class. In Worker class,it includes two field, nYearWked and curSalary, and constructor(s).It defines the CalcYearWorked() function using (current year –yearStartedWked) and save it in the nYearWked variable. It alsodefines the CalcCurSalary() function that calculates the currentyear salary by using initial salary with 3% yearly increment.Create a Manager class that is derived from Worker class. InManager class, it includes one field: yearPromo and constructor(s).Itincludes a CalcCurSalary function that calculate the current yearsalary by overriding the base class function using initial salarywith 5% yearly increment plus 10% bonus. The manager’s salarycalculates in two parts. It calculates as a worker before the yearpromoted and as a manager after the promotion. Write an applicationthat reads the workers and managers information from files(“worker.txt” and “manager.txt”) and then creates the dynamicarrays of objects. Prompt the user for current year and display theworkers’ and managers’ current information in separate groups:first and last name, ID, the year he/she has been working, andcurrent salary.

HELP:

The error that is constantly showing up is the index is out ofbounds of the array with the source being LINE 21 in theEmployeeMain Class.
