| BETA-PRB: No Method in DataReader Closes Its Underlying Connection (Q310369) |
| Microsoft Support |
| The DataReader object does not include a property to retrieve its underlying connection. Although you can close DataReader and then close the OleDbConnection or SqlConnection object on which DataReader was opened, DataReader does not have a built-in connection. Thus, if you retrieve a DataReader from a component method, you cannot close the underlying connection. That is, if you retrieve a DataReader object from a component, the DataReader stays connected, and there is no way to disconnect it.

| Building a Custom Data Provider for Use with the .NET Data Access Framework |
| MSDN |
| The System.Data.dll assembly in the .NET Framework contains namespaces whose base classes can be used to create custom data providers. These namespaces also define a number of data access interfaces and base classes that let developers create data providers that will interoperate with other custom providers. Using the ADO.NET classes Connection, Command, DataReader, and DataAdapter, writing a provider is easier than writing one for OLE DB. This article explains these classes and their implementation, and how they can be used to write a variety of different kinds of data providers. |

| Commands in ADO .NET |
| MSDN |
| In ADO there are three possible ways to update a data source. One is through direct SQL commands, like INSERT, DELETE and UPDATE, or more complex and sophisticated stored procedures. Another is through batch update, where you submit a new image of a certain table to the server all at once. The third way is through direct fields update using server cursors. |
