[Mono-list] Checking key existance in a NameValueCollection

[Fabien Meghazi]

Sorry for this silly question, but I'm new to mono.

I'm trying to check if a key exists in the NameValueCollection
HttpContext.Current.Request.Form and I don't know how to do this.
I checjed the doc of NameValueCollection, I googled on this but found nothing
The only way I found is to check the string[] fetched with the help of AllKeys
but it seems heavy for just a check. Is there another way?
