Iterating thorugh a list and elimianting selected items

Hi All,
  I have a list of Test class. I want to eliminate some of the items from the list based on the parameters that is passed so I need something like this:
List<Test> This list contains the items like
120 - This is Test 1 121 - This is Test2 123 - This is Test3 145 - This is Test6 177 - This is Test11 ... I have 800 items in this list. I want to iterate through this list of Test class and eliminate those items that I am passing as a parameter:
 
The parameters that I will be passing is List<int32?> and it might contain 145, 177, 121 so I want to get a final list that have
120 - This is Test 1 123 - This is Test3 Any help will be greatly appreciated.
