To define an error-specific custom page, you add an <error> element to the <customErrors> element. The <error> element identifies the HTTP error code and the redirect page. <configuration> <system.web> <customErrors defaultRedirect="DefaultError.aspx"> <error statusCode="404" redirect="404.aspx" /> <customErrors> </system.web> </configuration> In this example, the user will be redirected to the 404.aspx page when requesting an ASP.NET page that doesn t exist. This custom error page may not work exactly the way you expect, because it comes into effect only if ASP.NET is handling the request. For example, if you request the nonexistent page whateverpage.aspx, you ll be redirected to 404.aspx, because the .aspx file extension is registered to the ASP.NET service. However, if you request the nonexistent page whateverpage.html, ASP.NET will not process the request, and the default redirect setting specified in IIS will be used. When an error occurs that isn t specifically addressed by a custom <error> element, the default error page will be used.

You can also add comments to an XML document. Comments go just about anywhere and are ignored for data processing purposes. Comments are bracketed by the <!-- and --> character sequences. The following listing includes three valid comments: < xml version="1.0" > <SuperProProductList> <!-- This is a test file. --> <Product ID="1" Name="Chair"> <Price>49.33<!-- Why so expensive --></Price> <Available>True</Available> <Status>3</Status> </Product> <!-- Other products omitted for clarity. --> </SuperProProductList> The only place you can t put a comment is embedded within a start or end tag (as in <myData <!-A comment should not go here --></myData>).

The DirectoryInfo and FileInfo classes mirror the functionality in the Directory and File classes. In addition, they make it easy to walk through directory and file relationships. For example, you can easily retrieve the FileInfo objects for the files in a directory represented by a DirectoryInfo object. Note that while the Directory and File classes expose only methods, DirectoryInfo and FileInfo provide a combination of properties and methods. For example, while the File class had separate GetAttributes() and SetAttributes() methods, the FileInfo class includes an Attributes property.

.NET provides a rich set of classes for XML manipulation in several namespaces that start with System.Xml. One of the most confusing aspects of using XML with .NET is deciding which combination of classes you should use. Many of them provide similar functionality in a slightly different way, optimized for specific scenarios or for compatibility with specific standards. The majority of the examples you ll explore use the types in the core System.Xml namespace. The classes here allow you to read and write XML files, manipulate XML data in memory, and even validate XML documents. In this chapter, you ll look at the following options for dealing with XML data: Reading and writing XML directly, just like you read and write text files using XmlTextWriter and XmlTextReader. For sheer speed and efficiency, this is the best approach. Dealing with XML as a collection of in-memory objects using the XDocument class. If you need more flexibility than the XmlTextWriter and XmlTextReader provide or you just want a simpler, more straightforward model (and you don t need to squeeze out every last drop of performance), this is a good choice. Using the Xml control to transform XML content to displayable HTML. In the right situation when all you want to do is display XML content using a prebuilt XSLT style sheet this approach offers a useful shortcut.

Another nice thing about the DirectoryInfo and FileInfo classes is that they share a common set of properties and methods because they derive from the common FileSystemInfo base class. Table 18-4 describes the members they have in common.

Note When it comes to XML, Microsoft is a bit schizophrenic. The .NET Framework includes at least a dozen

Instead of extending from the interface as you would an abstract class, use the implements keyword: class ExampleClass implements IExampleInterface {} If you mark a class as implementing an interface and fail to implement all the interface s methods, you will see an error similar to this: Fatal error: Class ExampleClass contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (IExampleInterface::exampleMethod) This error means that if any method in an interface is not declared, it is assumed that the method is abstract. And since any class containing an abstract method must also be abstract, the class must be marked as abstract to be parsed successfully. To resolve this error, implement
