VB.Net Lambda Expression

Please can someone assist.

I am wanting to filter a list of items based on another list.

I have a list of Electronics Device Models.

I have and add function which allows the user to add models to the list.

Within the Add function I have a combo box which contains all of the possible Models in my database.

I want to be able to filter the Items in the Combo Box to ensure that the user cannot select a Model that is already in the list.

I thought I could do this as a Lambda expression, but it seems there is not a NOT IN function available?

Have you tried to use the Except method?

Produces the set difference of two sequences by using the default equality comparer to compare values.
