Quiz














1:

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


A1:

Command

2:

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


A2:

DataSet

3:

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


A3:

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.


A4:

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.


A5:

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

6:

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


A6:

DataSet, DataReader
