Binary serialization is the fastest and most compact serialization type. Binary serialization is included in the base class library, mscorlib.dll, so no references need be made to external .dll files. Binary serialization classes are located in the System.Runtime.Serialization .Formatters.Binary namespace. To serialize and store the ShoppingCart to a disk file, the btnPopulateCart_click method can be modified as follows:

Private Sub btnPopulateCart_Click( _ ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles btnPopulateCart.Click Dim ShoppingCart As New ArrayList() ShoppingCart.Add(New LineItem( Apple-123 , 1)) ShoppingCart.Add(New LineItem( Orange-234 , 2)) ShoppingCart.Add(New LineItem( Pear-567 , 3)) ShoppingCart.Add(New LineItem( Plum-890 , 4)) ShoppingCart.Add(New LineItem( Grape-999 , 5)) Dim filename As String = c:\cart.bin Dim s As New FileStream(filename, FileMode.Create) Dim f As New BinaryFormatter() f.Serialize(s, ShoppingCart) s.Close() End Sub

Deserializing the shopping cart is a relatively simple task. The following code deserializes the ShoppingCart and displays the LineItems in a DataGrid:

Private Sub btnRestoreCart_Click( _ ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles btnRestoreCart.Click Dim ShoppingCart As ArrayList Dim filename As String = c:\cart.bin Dim s As New FileStream(filename, FileMode.Open) Dim f As New BinaryFormatter() ShoppingCart = CType(f.Deserialize(s), ArrayList) s.Close() DataGrid1.DataSource = ShoppingCart DataBind() End Sub

This code declares an ArrayList, but does not create the instance of the ArrayList. The stream is created, thus essentially opening the file. The ShoppingCart is deserialized, but the BinaryFormatter always returns an object data type, so the CType command is used to cast the object to the desired ArrayList. Finally, the ShoppingCart is assigned to the DataGrid, and the DataBind command is executed. The browser output is shown in Figure 10.19.

SOAP Serialization

SOAP serialization is the most cross-platform-compatible method of serialization, but it is also the most verbose serialization type. SOAP serialization is not included in the base class library, so a reference must be added to the System .Runtime.Serialization.Formatters.Soap.dll file.

The SOAP serialization classes are located in the System.Runtime.Serialization .Formatters.Soap namespace, so the following imports statement is added to the top of the code-behind page:
Control qr bidimensional barcode size for .net

To serialize and store the ShoppingCart to a disk file, the btnPopulateCart_click method can be modified as follows:

Private Sub btnPopulateCart_Click( _ ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles btnPopulateCart.Click Dim ShoppingCart As New ArrayList() ShoppingCart.Add(New LineItem( Apple-123 , 1)) ShoppingCart.Add(New LineItem( Orange-234 , 2)) ShoppingCart.Add(New LineItem( Pear-567 , 3)) ShoppingCart.Add(New LineItem( Plum-890 , 4)) ShoppingCart.Add(New LineItem( Grape-999 , 5)) Dim filename As String = c:\cart.xml Dim s As New FileStream(filename, FileMode.Create) Dim f As New SoapFormatter() f.Serialize(s, ShoppingCart) s.Close() End Sub

Deserializing the shopping cart is the same as using the binary formatter, except that the filename and formatter are different. The following code deserializes the ShoppingCart and displays the LineItems in a DataGrid:
Streams, File Access, and Serialization
Private Sub btnRestoreCart_Click( _ ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles btnRestoreCart.Click Dim ShoppingCart As ArrayList Dim filename As String = c:\cart.xml Dim s As New FileStream(filename, FileMode.Open) Dim f As New SoapFormatter() ShoppingCart = CType(f.Deserialize(s), ArrayList) s.Close() DataGrid1.DataSource = ShoppingCart DataBind() End Sub
The only change is the filename and the use of the SoapFormatter instead of the BinaryFormatter. This code produces the XML file shown in Figure 10.20. Note that the data is very readable, but is very verbose, which may influence whether a programmer chooses to use SOAP serialization. Before looking at XML serialization, some changes can be made to the code to reduce the verbosity of this file. First, much of the verbosity is from namespaces. This can be reduced by declaring a very short namespace for the ListItem class. If the namespace is eliminated, the class cannot be deserialized, so a dot (.) is used as the namespace, as shown in the following attribute:
<System.Runtime.Remoting.Metadata.SoapType(XmlNamespace:= . ), _ Serializable()> _ Public Class LineItem End Class
