VirtualFile Private _FileContent As String Public Sub New(ByVal virtualPath As String, ByVal fileContent As String) MyBaseNew(virtualPath) _FileContent = fileContent End Sub Public Overrides Function Open() As Stream Dim strm As New MemoryStream() Dim writer As New StreamWriter(strm, EncodingUnicode) writerWrite(_FileContent) writerFlush() strmSeek(0, SeekOriginBegin) Return strm End Function End Class The class s constructor gets the virtual path as well as the content of the file In the Open method, the string with the actual content gets saved to a MemoryStream, and this stream is then returned ASP NET uses the stream for reading the contents as if they were read from the file system thanks to the abstraction of bytes through Stream classes The next step is to complete the VirtualPathProvider class It needs to read the actual data for the files from the database.

The SoapFormatter type persists an object s state as a SOAP message (the standard XML format for passing messages to/from a web service). This type is defined within the System.Runtime.Serialization.Formatters.Soap namespace, which is defined in a separate assembly. Thus, to format your object graph into a SOAP message, you must first set a reference to System.Runtime.Serialization.Formatters.Soap.dll using the Visual Studio 2010 Add Reference dialog box and then specify the following C# using directive: // Must reference System.Runtime.Serialization.Formatters.Soap.dll. using System.Runtime.Serialization.Formatters.Soap; Finally, if you wish to persist a tree of objects as an XML document, you can use the XmlSerializer type. To use this type, you need to specify that you are using the System.Xml.Serialization namespace and set a reference to the assembly System.Xml.dll. As luck would have it, all Visual Studio 2010 project templates automatically reference System.Xml.dll; therefore, all you need to do is use the following namespace: // Defined within System.Xml.dll. using System.Xml.Serialization;

If a file doesn t exist in the database, the provider just forwards the request to its previous provider (which has been selected by the infrastructure while registering in the Shared Appinitialize method) Add a method for retrieving the contents from the database to the MyProvider class introduced previously: Private Function GetFileFromDB(ByVal virtualPath As String) As String Dim contents As String Dim fileName As String = virtualPathSubstring(virtualPathIndexOf("/"c, 1) + 1) ' Read the file from the database Dim conn As New SqlConnection() connConnectionString = "data source=(local);Integrated " _ & "Security=SSPI;initial catalog=AspContent" connOpen().

Regardless of which formatter you choose to use, be aware that all of them derive directly from System.Object, so they do not share a common set of members from a serialization-centric base class. However, the BinaryFormatter and SoapFormatter types do support common members through the implementation of the IFormatter and IRemotingFormatter interfaces (strange as it might seem, the XmlSerializer implements neither). System.Runtime.Serialization.IFormatter defines the core Serialize() and Deserialize() methods, which do the grunt work to move your object graphs into and out of a specific stream. Beyond these members, IFormatter defines a few properties that the implementing type uses behind the scenes: public interface IFormatter { SerializationBinder Binder { get; set; } StreamingContext Context { get; set; } ISurrogateSelector SurrogateSelector { get; set; } object Deserialize(Stream serializationStream); void Serialize(Stream serializationStream, object graph); } The System.Runtime.Remoting.Messaging.IRemotingFormatter interface (which is leveraged internally by the .NET remoting layer) overloads the Serialize() and Deserialize() members into a manner more appropriate for distributed persistence. Note that IRemotingFormatter derives from the more general IFormatter interface: public interface IRemotingFormatter : IFormatter { object Deserialize(Stream serializationStream, HeaderHandler handler); void Serialize(Stream serializationStream, object graph, Header[] headers); }

Returning data to the view Components Application assembly Most of the times architected by the developer

Although you might not need to interact directly with these interfaces for most of your serialization endeavors, recall that interface-based polymorphism allows you to hold an instance of BinaryFormatter or SoapFormatter using an IFormatter reference. Therefore, if you wish to build a method that can serialize an object graph using either of these classes, you could write the following: static void SerializeObjectGraph(IFormatter itfFormat, Stream destStream, object graph) { itfFormat.Serialize(destStream, graph); }
