This article describes best practices for handling and creating exceptions.Handling exceptionsThe following list contains some general handling in vb guidelines for handling exceptions in your app.Use exception handling code (try/catch blocks) appropriately. You can also programmatically check for a condition that is likely to occur without using exception handling. Programmatic checks. The following example uses an if statement to check whether a connection is closed. If it isn't, the example closes the connection instead of throwing an exception. C#C++VB Copy if (conn.State != ConnectionState.Closed) { conn.Close(); } Exception handling. The following example uses a try/catch block to check the connection and to throw an exception if the connection is not closed. C#C++VB Copy try { conn.Close(); } catch (InvalidOperationException ex) { Console.WriteLine(ex.GetType().FullName); Console.WriteLine(ex.Message); } The method you choose depends on how often you expect the event to occur. Use exception handling if the event doesn't occur very often, that is, if the event is truly exceptional and indicates an error (such as an unexpected end-of-file). When you use exception handling, less code is executed in normal conditions.Use the programmatic method to check for errors if the event happens routinely and could be considered part of normal execution. When you check for errors programmatically, more code is executed if an exception occurs.Use try/catch blocks around code that can potentially generate an exception,

In this tutorial we will look into at creating a Class Library to help with dealing with exception handling in a custom way. As a developer all of us have the same goal, to write error free applications, but the chances of that are about the same as finding Bigfoot. As we all know, the end user will always find a way to break our applications, in ways we never thought of in the first place. We can ask them "What were doing when the error happened" and, across the board, the answer is always "I don't know." Then our next question, like we're trained robots, is "What did the error say", and we always get something from "It said something like
