LINQ Where with AND OR condition

Question

So I have managed to get this query working

List listStatus = new List() ; 
listStatus.add(\"Text1\");

List listMercha         


        

Answer 1

from item in db.vw_Dropship_OrderItems
    where (listStatus != null ? listStatus.Contains(item.StatusCode) : true) &&
    (listMerchants != null ? listMerchants.Contains(item.MerchantId) : true)
    select item;

Might give strange behavior if both listMerchants and listStatus are both null.
