(C#) I have 2 classes. 1 is called Employee. The other is my "main". I am trying to take a list and assign each value in list to an array of Employee object.

//Inside "Main" class
int counter = NameList.Count;

        Employee[] employee = new Employee[counter];

        for (int i = 0; i <= counter; i++)
        {
            employee[i].Name = NameList[i];
            employee[i].EmpNumber = EmpNumList[i];
            employee[i].DateOfHire = DOHList[i];
            employee[i].Salary = SalaryList[i];
            employee[i].JobDescription = JobDescList[i];
            employee[i].Department = DeptList[i];
        }

This returns the error:

An unhandled exception of type 'System.NullReferenceException' occurred in Pgm4.exe Additional information: Object reference not set to an instance of an object.

I think this means that I am not calling the list properly. Any help would be much appreciated. Thank you.
