Question

Suppose I have a collection of strings.
How do I select all the elements that don’t contain a certain parameter value?

List<string> TheList = .....

var TheCleanList = (from s in TheList
                    where s != parameter
                    select s).ToList();

I was thinking about where s!= parameter but I’m wondering if there’s a cleaner way to do it.

Thanks.

If you don’t need a new list you don’t need Linq for this – use Remove()– this avoids having to create a new list:

If you want to remove all strings that are equal to Parameter:

TheList.RemoveAll(s => s == Parameter);

If you want to remove all strings that contain Parameter (not clear from your question):

TheList.RemoveAll(s => s.Contains(Parameter));
