Question

I am trying to use App keys as below :

<add key="APPLE" value="TESTER"/>
<add key="apple" value="TESTER"/>
<add key="ORANGE" value="DEVELOPER"/>

Now the Problem is that when I am using AllKeys as:

WebConfigurationManager.AppSettings.AllKeys.Contains(Fruits)

AllKeys just contains key for APPLE and ORANGE and nothing comes for “apple”.
Is it because, both “apple” and “APPLE” has same value as “TESTER “

or else Allkeys conflicts between keys for “APPLE” and “apple”

Any pointers ??

AppSettings is a NameValueCollection who’s default comparer is the CaseInsensitiveComparer
