Initialize collection of a string array (System.Collections.Generic.ICollection<System.String[]>)

I know how to initialize collection and array individually but how do I initialize a collection of a string array such as (System.Collections.Generic.ICollection<System.String>)?

give a try on
new List(Of String())

Thank you so much. I am also wondering if there is a way to limit the array inside the collection to size 2?
