Employee Class -- Program language: VISUAL C# Programming -- full application code

Create an application with a class named Employee, which contains the following:

Private fields for an employee's name, ID number, department, and position of appropriate data type

Constructor which does not receive any arguments and initializes the private fields to the appropriate value

Parameterized Constructor which receives four arguments and assigns the values to the private fields

Properties which get and set the values of the corresponding private fields

The application should contain a Main form which allows the user to enter the employee's name, ID number,

department, and position. An Employee object should be instantiated and the values entered by the user should be

assigned to the private fields of the object using either the Parameterized Constructor or the Properties. The Add

Employee button should add the Employeee objects to a List object and each employee's name should be displayed

in a list box on the Main form. The Add Employee button should also clear the text boxes and set the focus to the

Name text box. All information is REQUIRED and a message should be displayed if any text box is left blank and

focus should return to the text box. Additionally, the ID number should be validated to ensure appropriate data type

(i.e., whole number) and that it is greater than zero. In each case of invalid data, a message should be displayed, the

text box cleared, and focus set back to the text box causing the error. The Clear button should clear ALL the controls

on the form and set the focus to the Name text box.

When the user selects a name from the list box, a second form (provide a descriptive name) should appear displaying

that employee's name, ID Number, department, and position by referencing the Employee objects that have been

added to the List object as shown in the sample second form shown below (hint: be sure and utilize the Properties):

IMPORTANT: Accessing Controls on a Different Form

It is possible for code that is outside the forms class to access the controls (e.g., labels, text boxes, etc.) on that form.

Controls that are placed on a form have Private access by default. In order for code that is outside the forms class to

access controls on that form the Modifiers property MUST be changed to Public. An alternative is to pass the List object as an argument to the form

The program MUST include standard features of a Windows application including:

Change the default Text property of the forms to something descriptive

Appropriate naming conventions for all controls (i.e., buttons, labels, text boxes, list, list box)

Buttons with appropriate name and standard keyboard access key

AcceptButton and CancelButton properties should be appropriately assigned to the Add Employee button and

Clear button, respectively

Ensure tab order for form is logical

Appropriate naming conventions and data type declarations for variables

Remove all unused event handlers from the program code
