In C#, can I get the number of opened tabs?

            C# generally runs at the server (unless you are talking about Silverlight etc), so there will be no way of knowing much about the client. Likewise, I would not expect this information to be exposed unless you are writing a browser extension / add-in. Basically, I think the short version is "no".
