This schema can be modified if required (I set the price field to be a decimal rather than a string), and then the вЂњGenerate DatasetвЂќ option on the Schema menu can be used to automatically generate a C# class. Visual Studio will automatically generate a Schema (XSD) file for this XML file if you select the вЂњCreate SchemaвЂќ option from the вЂњXMLвЂќ menu that appears when editing an XML file. One solution is to provide product information in an XML file вЂ“ a simple example is:

It is not desirable to write new code (HTML or C#) to add these products, especially since this would usually require down-time on the server. The best way to explain how this functionality can be used is with an example.ДЄ web shop typically has a product list that is updated infrequently compared with the frequency of page hits, but much more often than the structure of the site. Unlike the Application and Session collections, the Page.Cache collection allows you to add expiry times and dependencies to the stored items. The Application collection is in some ways similar to the Session collection described in the February 2004 edition of VSJ in an excellent article by Dino Esposito, Getting Serious about ASP.NET Session Management (However, the data in the Application collection is always stored In-Process and is therefore not shareable across multiple machines.ДЄn alternative to using a FileSystemWatcher to monitor the filesystem in ASP.NET is to make use of the built-in features of the Page cache. First we must retrieve a reference to the object from the application collection, then remove it from the collection, and finally dispose the object:

The following function shows how to do this. To be a good citizen we should ensure that we dispose of this object properly at application end.

Note the use of the Server.MapPath function to obtain the full path of the application directory from the relative path provided by IIS. The basic code for adding a FileSystemWatcher to an ASP.NET application looks like this: Care should be taken when applying synchronisation in a server environment to ensure that performance and scalability are not compromised. To manage the lifecycle of the FileSystemWatcher it must be stored in this collection.Д®vent handlers for the FileSystemWatcher events may be added to the Global class, but you must ensure that they only access data in the Application collection, and that they do so in a thread-safe manner (see my previous article). This seems like the obvious place to put our FileSystemWatcher object, but although Global.asax defines a class named Global (derived from HttpApplication), the ASP.NET system will not necessarily use the same instance of this object for all of the events handled there!ДЄpplications in ASP.NET store application-wide information in name/value pairs in the AllKeys collection of the Application object (a member of HttpApplication and thus Global), and ASP.NET does ensure that the Application object is the same for each event handled. When you create a project with Visual Studio it automatically creates for you a Global.asax file that contains handlers for the principle events in the lifecycle of an application including Start and End. In this article I will show how FileSystemWatcher can be used within web applications, and then go on to describe the Cache mechanism that provides an ASP.NET specific alternative.

Some of the responses I received were asking about the use of FileSystemWatcher within ASP.NET applications, for example to update a product list. This would allow files to be copied up to a file-based web server (e.g. The original article mentioned using FileSystemWatcher to update files on a web server, and the model I envisaged was similar to the Photo Library application described in the article. _myFolderPath is being set correctly, I have checked.I received a number of responses to my article in the July/August edition of VSJ, Your fingers on the filesystem, regarding the use of the FileSystemWatcher class in ASP.NET applications. I want to know any time a new file is created, deleted or renamed in my directory. For some reason, my FileSystemWatcher is not firing any events whatsoever.
