Chap 1 pg 48 OpenStream not referencing

tomche · September 20th, 2009, 03:06 AM

Hello,
I have just done the example on page 48 and the OpenStream is underlined in red.

I can't see that it is supposed to be delcared in the program and I can't see any values in the web.config file that say OpenStream so I suppose it is a referene to another file or the Stream wasn't declared properly.

My code is the same as the book.

Where does the Car.cs file reference the OpenStream variable from?

Hi tomche,

OpenStream is defined in the base class BuildProvider, that Car inherits from:

Thanks Imar, but am I wrong in saying that the build providers are located in the web.config file?

This Chapter asks to start a class library so I don't have a web config file unless I create one. Also the chapter speaks of an AppCode folder on page 49.

Is there simething I haven't done?

Cheers

You hook up extensions to build providers in web.config. The build provider itself resides in a class you define yourself.

If you create a web site or web application the code for Car.cs should work as is (in App_Code for a web site, in a different folder like Classes for a Web Application Project), as those projects contain a reference to System.Web out of the box which contains the base class for the buildprovider.

A class library could work as well, but you need to manually add a reference to System.Web using the Add Reference dialog.
