C# Comet 'pull' application to receive google finance prices?

Is it possible to use WebRequest in C# to write 开发者_如何学Goa small application which mimicks what a google finance webpage does, when it automatically updates the graph and price when viewing a stock?

I just wish to have a client waiting and then be sent 'pushed' a new price from the google server?

Sure you can do that. http://msdn.microsoft.com/en-us/library/456dfw4f.aspx
