Count: Integer;
The Count property returns the number of objects in the collection.
Collection capacity is the number of elements a collection can contain. The Count property is the number of elements, which is actually contained in the collection.
The capacity is always greater or equal to the value of the Count property. If value of the Count property is greater than the capacity when an element is added to the collection, the capacity is automatically increased.
The property use is given in the example for IMsFormulaTransformVariable.AttributeId.
