Dynamically generate control arrays in. net

The majority of developers started from BASIC, and Windows developers started from VB. The changes from vb to vb.net are indeed not small, in the past, a lot of control arrays were used in. net, but the time is okay. This is used in one of my programs. Today, I pasted this class, this is what I saw from MSDN a long time ago.

Public class textBoxArray: System. Collections. CollectionBase

Private readonly System. Windows. Forms. Form HostForm;
// Constructor
Public textBoxArray (System. Windows. Forms. Form Host)
{
HostForm = Host;
}
// Add a textbox control using the addNewTextBox method
Public void addNewTextBox ()
{
If (this. Count <7)
{
// Create a new textbox instance.
System. Windows. Forms. TextBox aTextBox = new System. Windows. Forms. TextBox ();
// Add it to the internal list of the set
This. List. Add (aTextBox );
// Add TextBox to the set list of the forms referenced by the HostForm field
HostForm. Controls. Add (aTextBox );
// Set the initial attribute
ATextBox. Left = (Count-1) * 130 + 70;
ATextBox. Top = 160;
