Quiz

1. The ______________ object in ADO.NET handles the execution of SQL statements for the DataReader and DataAdapter classes.

   Command

2. The DataReader is used for forward-only reading of data. To be able to reuse data from a database, manipulate the __________ class.

   DataSet

3. True or False: The SqlDataAdapter and OleDataAdapter share the same functionality.

   False. The answer is misleading, though. The two classes share about 98% of the same functionality, with DataType classes being the main difference.

4. True or False: You don't need to use a Connection object with the DataAdapter class because it handles all connection information for you.

   False. You still must set connection parameters. The DataAdapter explicitly opens a connection for you. You don't have to use connection.open.

5. True or False: The DataBindings collection in .NET only supports DataSets and XML files for simple and complex binding to the Label control, the DataGrid control, and the TextBox control.

6. False. You can use the DataBindings collection with many controls, and the only complex binding mentioned in the question would be the DataGrid control.

   In Web Forms, I can use the _____________ object and the ___________ object to bind controls to a data source.

   DataSet, DataReader
