F# ListBox Oluşturmak | ListBox Constructor

new : unit -> ListBox

The following code example demonstrates how to create a ListBox control 

that displays multiple items in columns and can have more than one item 

selected in the control's list. The code for the example adds 50 items 

to the ListBox using the Add method of the ListBox.ObjectCollection class

and then selects three items from the list using the SetSelected method. 

The code then displays values from the ListBox.SelectedObjectCollection 

collection, through the SelectedItems property, and the 

ListBox.SelectedIndexCollection, through the SelectedIndices property. 

This example requires that the code is located in and called from a Form.
