Tutorial Details:

Professional C# 2nd Edition : Data Access with .NET With ASP Database

In this chapter, we'll be discussing how to get at data from your C# programs using ADO.NET. Over the course of this chapter, we'll be covering the following areas:

Connecting to the database - how to utilize the new SqlConnection and OleDbConnection classes to connect to and disconnect from the database.

Connections utilize the same form of connection strings as did OLEDB providers (and therefore ADO), and these are briefly discussed. We then go through a set of best practices for utilizing database connections, and show how to ensure that a connection is closed after use, which is one of the sources of poor application performance.

Executing Commands - ADO.NET has the concept of a command object, which may execute SQL directly, or may issue a stored procedure with return values. The various options on command objects are discussed in depth, with examples to show how commands can be used for each of the options presented by the Sql and OleDB classes.
