Using LINQ to remove elements from a List

Question

Say that I have LINQ query such as:

var authors = from x in authorsList
              where x.firstname == \"Bob\"
              select x;

Answer 1

Below is the example to remove the element from the list.

 List items = new List() { 2, 2, 3, 4, 2, 7, 3,3,3};

 var result = items.Remove(2);//Remove the first ocurence of matched elements and returns boolean value
 var result1 = items.RemoveAll(lst => lst == 3);// Remove all the matched elements and returns count of removed element
 items.RemoveAt(3);//Removes the elements at the specified index
