Return Value

Type: SystemType
An array of data types that this collection can contain.
Remarks

You can retrieve the data type of the items of the collection from the NewItemTypes property, which is faster than this method.

This method does not need to be called by users, except in derived classes where this method has been overridden and implemented.

The default implementation of this method returns the type of all the collection items in a Type array.

Notes to Inheritors

This method must be overridden to support collections with multiple types. The default implementation of this method returns the data type of the Item property of the collection, if it exists. Use this method to override the default implementation.
