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

LINQ has its origins in functional programming, which emphasises immutability of objects, so it doesn't provide a built-in way to update the original list in-place.

Note on immutability (taken from another SO answer):

Here is the definition of immutability from Wikipedia.

In object-oriented and functional programming, an immutable object is an object whose state cannot be modified after it is created.
