is there anyway to remove from a collection based on a .Where() linq clause (.RemoveWhere() ?)

Question

I see a collection has a .Remove() and a .RemoveAt() method. I would like to do something like this:

  myObject.ChildList.RemoveWhere(r=>r.Name == "Joe");

What is the best way to achieve this besides doing a seperate where and then a loop through each item and them calling .Remove()

Answer 1

List<T> has a RemoveAll method that accepts a predicate.

myObject.ChildList.RemoveAll(r => r.Name == "Joe");

Answer 2

You could write RemoveWhere() as an extension method. But changing collections is tricky and sometimes very inefficient.

Why not create a new collection?

myObject.ChildList = myObject.ChildList.Except(
      myObject.ChildList.Where(r=>r.Name == "Joe"));
