Execute the Application

Now that we have completed the steps necessary to design the Web form and create the appropriate methods to handle interaction with the database, it is time to test. Within the Visual Studio .NET IDE, press the F5 key to run the application.  Enter test data and click the Add Authors button. If the insert into the database is successful, a screen similar to the following should be displayed.

To take this a step further, query the database to ensure the data was successfully inserted.

Conclusion

As you can see, using the ArrayBindCount property allows the developer to make a single call to the database using a stored procedure or SQL statement. The beauty of this is that the execution happens at the database level with a single call versus a loop, which would require a total of three round trips. While this may not be feasible in every situation, e.g., where you do not know ahead of time how many rows will be processed, it is a perfect solution for those times that you do know how many rows you are to process.
