Handling Exceptions

Summary

We began this chapter by reviewing VB .NET’s structured error handling. Then we discussed the sources of exceptions in ADO.NET database applications.

You saw how to handle exceptions thrown by the CLR and by the database. In particular, you learned how to handle both single and multiple database exceptions with the System.Data.SqlClient.SqlException class.

In the next chapter, you’ll look at transactions and how to maintain database integrity when multiple users are working concurrently.
