The following code shows what's needed to serialize a DataTable object using a binary formatter: BinaryFormatter bf = new BinaryFormatter(); StreamWriter swDat = new StreamWriter(outputFile); bf.Serialize(swDat.BaseStream, dataTable); swDat.Close(); The Serialize method causes the formatter to flush the contents of an object to a binary stream. The Deserialize method does the reverse it reads from a previously created binary stream, rebuilds the object, and returns it to the caller, as shown here: DataTable dt = new DataTable(); BinaryFormatter bf = new BinaryFormatter(); StreamReader sr = new StreamReader(sourceFile); 343

A document library, shown in Figure 1-5, is a folder for holding documents, images, or forms. Each document library can have its own custom permissions separate from the general WSS site. For example, someone might have Contributor permissions that allow them to add and delete content to a WSS site, but still might have only Reader permissions in one of the document libraries. WSS document libraries can hold a variety of document formats, such as Microsoft Office documents, Adobe PDF files, image files, and Microsoft InfoPath forms.

dt = (DataTable) bfDeserialize(srBaseStream); srClose(); When you run this code, something surprising happens Have you ever tried to serialize a DataTable object, or a DataSet object, using the binary formatter If so, you certainly got a binary file, but with a ton of XML in it Unfortunately, XML data in serialized binary files only makes them huge, without the portability and readability advantages that XML normally offers As a result, deserializing such files might take a while to complete usually seconds There is an architectural reason for this odd behavior The DataTable and DataSet classes implement the ISerializable interface, thus making themselves responsible for the data being serialized The ISerializable interface consists of a single method GetObjectData whose output the formatter takes and flushes into the output stream.

Can you guess what happens next By design, the DataTable and DataSet classes describe themselves to serializers using an XML DiffGram document The binary formatter takes this rather long string and appends it to the stream In this way, DataSet and DataTable objects are always remoted and transferred using XML which is great Unfortunately, if you are searching for a more compact representation of persisted tables, the ordinary NET Framework run-time serialization for ADONET objects is not for you Let's see how to work around it Custom Binary Serialization To optimize the binary representation of a DataTable object (or a DataSet object), you have no other choice than mapping the class to an intermediate object whose serialization process is under your control The entire operation is articulated into a few steps: 1 Create a custom class, and mark it as serializable (or, alternatively, implement the ISerializable interface) 2.

Figure 1-5. A document library is a container for documents, images, or forms. A list, such as the one shown in Figure 1-6, is a folder that holds data organized into customizable columns and rows. A list can also have its own permissions, and can be displayed in a standard list view and in Datasheet view, resembling a spreadsheet.

Copy the key properties of the DataTable object to the members of the class Which members you actually map is up to you However, the list must certainly include the column names and types, plus the rows 3 Serialize this new class to the binary formatter, and when deserialization occurs, use the restored information to build a new instance of the DataTable object Let's analyze these steps in more detail Creating a Serializable Ghost Class Assuming that you need to persist only columns and rows of a DataTable object, a ghost class can be quickly created In the following example, this ghost class is named GhostDataTable: [Serializable] public class GhostDataTable { public GhostDataTable() { colNames = new ArrayList(); colTypes = new ArrayList(); dataRows = new ArrayList(); } public ArrayList colNames; public ArrayList colTypes; 344.

Save the Normal.dot template. To ensure the template is indeed saved as a template, select .dot in the drop-down box labeled Save as type in the Save As dialog box (see Figure 9-13).

public ArrayList dataRows; } This class consists of three, serializable ArrayList objects that contain column names, column types, and data rows. The serialization process now involves the GhostDataTable class rather than the DataTable object, as shown here: private void BinarySerialize(DataTable dt, string outputFile) { BinaryFormatter bf = new BinaryFormatter(); StreamWriter swBin = new StreamWriter(outputFile); // Instantiate and fill the worker class GhostDataTable ghost = new GhostDataTable(); CreateTableGraph(dt, ghost); // Serialize the object bf.Serialize(swBin.BaseStream, ghost); swBin.Close(); } The key event here is how the DataTable object is mapped to the GhostDataTable class. The mapping takes place in the folds of the CreateTableGraph routine. Mapping Table Information The CreateTableGraph routine populates the colNames array with column names and the colTypes array with the names of the data types, as shown in the following code. The dataRows array is filled with an array that represents all the values in the row. void CreateTableGraph(DataTable dt, GhostDataTable ghost) { // Insert column information (names and types) foreach(DataColumn col in dt.Columns) { ghost.colNames.Add(col.ColumnName); ghost.colTypes.Add(col.DataType.FullName); } // Insert rows information foreach(DataRow row in dt.Rows) ghost.dataRows.Add(row.ItemArray); } The DataRow object's ItemArray property is an array of objects. It turns out to be particularly handy, as it lets you handle the contents of the entire row as a single, monolithic piece of data. Internally, the get accessor of ItemArray is implemented as a simple loop that reads and stores one column after the next. The set accessor is even 345

more valuable, because it automatically groups all the changes in a pair of BeginEdit/EndEdit calls and fires column-changed events as appropriate. Sizing Up Serialized Data The sample application shown in Figure 9-9 demonstrates that a DataTable object serialized using a ghost class can be up to 80 percent smaller than an identical object serialized the standard way.

Note In addition to libraries and lists, discussions and surveys can be added to SharePoint sites. Although
