Can an individual value be changed or must the entire collection for a
specific key be cleared and re added?

Bernie,

You should just be able to do this:

// pobjNameValueCollection is the NameValueCollection instance.
pobjNameValueCollection["key"] = "new value";

Hope this helps.
 
Lets say I have:
NameValueCollection nvc = new NameValueCollection():
nvc.Add("Saying","Apples");
nvc.Add("Saying","Peaches");
nvc.Add("Saying","Pumpkin Pie");

now I want to change the value of 'Pumpkin Pie' to 'Cherry Pie' for the key
'Saying'

Is there a way to access the third value of the key and change it?

Bernie.

Bernie,

You will have to call GetValues to get the value for the key. Once you
do that, you can replace the value you want, remove the origial values from
the list, and then re-add all the values.
