page.aspx?option - how to detect "option"

[Kevin Blount]

I've seen some sites that have URLs like this:

blahblah.com/page.aspx?option

i.e. there's no 'value' for the 'name' option. I'd like to find out how
to detect if the name' is part of the URL if there's no 'value'.

Can anyone tell me?

I can work with "?option=value&option2=value" no problem.. but I've been
trying all morning to get just "?option" to detect, without success.

Cheers and TIA

Kevin

Request.QueryString on its own will return everything which follows the ?

Mark,

Thanks for the reply, but I'm not sure how you're suggesting I use that
info.

Are you thinking of "string myURL = Request.QueryString;", or is there
something else you're suggesting?

Thanks

Kevin

Kevin,
in ASP.NET, Request.QueryString is a NameValueCollection object.
So, you can have a name whose value is null (or an empty string).
Take a look at NameValueCollection in the documentation, that will give
you a better scope on what you want to do.

In this case, NameValueCollection (nvc) will not help him as he wants to
detect "?option". If it was detecting "?option=", then nvc would have helped.
In case of "?option" the array of nvc will show a length of 1, but the key
name would be null. While there may better solutions, the one proposed by
Mark Rae is the easiest to implement.
