Gets the number of buttons in the toolbar button collection.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The property holds the actual number of ToolBarButton controls assigned to the collection. It is common to use the property value as the upper bounds of a loop to iterate through a collection. The index value of a collection is a zero-based index, so you must subtract one from the looping variable otherwise you will exceed the upper bounds of the collection and throw an exception.
