I had the idea of creating a class that is devoted to receiving and handling exceptions, but I am wondering c# error handling framework if its a good design idea. Such a class would receive an exception and then decide what to do with it depending on its type or error code, could even parse the stack trace for specific information, etc. Here is the basic idea behind and implementation: public class ExceptionHandler { public static void Handle(Exception e) { if (e.GetBaseException().GetType() == typeof(ArgumentException)) { Console.WriteLine("You caught an ArgumentException."); } else { Console.WriteLine("You did not catch an exception."); throw e; // re-throwing is the default behavior } } } public static class ExceptionThrower { public static void TriggerException(bool isTrigger) { if (isTrigger) throw new ArgumentException("You threw an exception."); else Console.WriteLine("You did not throw an exception."); } } class Program { static void Main(string[] args) { try { ExceptionThrower.TriggerException(true); } catch(Exception e) { ExceptionHandler.Handle(e); } Console.ReadLine(); } } I thought this would be an interesting endeavor because you would theoretically only need one or very few try / catch blocks around your main() method calls, and let the exception class handle everything else including

This article describes best practices for handling and creating exceptions.Handling exceptionsThe following list contains some general 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 in

This documentation is archived and is not being maintained. Defining Exception and Error Classes The DCS Software Factory can generate exception and error classes that let you implement strongly typed error handling in your services and client applications. You use the Add Error and Exception Classes recipe in the Messages project to define Exception and Error classes. For more information about creating a Messages project, see Defining Exception and Error Classes. Note: You can use the default exception and error message classes generated automatically by the DCS Software Factory if you do not create a Messages project and your operations do not need to customize the exceptions and errors that they can throw. To add exception and error classes to a messages project Right-click the message project, and then click Add Error and Exception Classes. In the Add Error and Exception Classes dialog box, type names for the exception and error classes, and then click Finish. Note:
