Removing items in List using LINQ [duplicate]

This question already has an answer here:

I have a List of type some entity

List

public class OrderLine
{
   public string productCode;
   public int quantity;


}

i need to remove items from the above List if the productCode is equal to some products.

List<string> ProductsToBeExcluded = new List<string>(){"1234","1237"};

so, from List<OrderLine> i need to remove products which are equal to 1234 and 1237

i have tried

  1. create a List<string> from List<OrderLine> using

      List<OrderLine> OrderLines = GetOrderLines();
      var ol = from o in OrderLines
            select o.ProductCode;
    

2.

  List<string> ProductsToBeExcluded = new List<string>(){"1234","1237"};
   var filtered = OrderLines.Except(ProductsToBeExcluded);

how do I proceed further in removing

thanks
