List<T>.RemoveAll();

[John Young]

Hi I have just started messing about with generics.
I have done this..

List<string> myList = new List<string>();

I've added strings to the list...

But now I want to clear the list completely...

myList.RemoveAll( ??? );

What is 'Predicate<string> match' ?? I cannot seem to understand how to
use this. I just want to remove all strings in the list so that the list is
empty again, ready for me to add more strings into it.

Thanks in advance.

Thank you for that explanation of Predicate.

to remove everything, you should call List<T>.Clear().

Predicate allows you to specify criteria for removal of only certain
object. for example, if I want to remove all even integers from an
integer list. I would supply a predicate that returns true if the integer
is even.
