is VS 2012 in debug mode so, I can see what line throws any error. problem is, that I have not been able to catch the line (or method) that is throwing the error. I originally thought that the Domain controller was causing this issue due to power settings. How can I capture exactly what error is bubbling its way up the stack? c# console share|improve this question asked Apr 9 '13 at 21:46 Matthew Knudsen 105315 Please edit your question with the eventvwr record like this. We'll need the info to see if this is a first or second chance exception and if its in your app or the .Net framework or at a lower level. –Jeremy Thompson Apr 9 '13 at 21:55 add a comment| 5 Answers 5 active oldest votes up vote 1 down vote accepted Does all that run in a loop of some kind? Or on a timer? Perhaps put a try-catch around the body of the loop or the method that runs all your code, add a logging framework of your choice (log4net or nlog seem good) and then in the catch log the exception. Most logging frameworks allow you to include the exception and will include stacktrace, etc. Putting debug logging throughout the process can also help to narrow down where it's happening. share|improve this answer answered Apr 9 '13 at 21:5

Exceptions and Exception Handling (C# Programming Guide) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 The C# language's exception handling features help you deal with any unexpected or exceptional situations that occur when a program is running. Exception handling uses the try, catch, and finally keywords to try actions that may not succeed, to handle failures when you decide that it is reasonable to do so, and to clean up resources afterward. Exceptions can be generated by the
Studio Languages , .NET Framework > Visual C# Question 0 Sign in to vote I was wondering how to catch thread exceptions in a console application. By looking online, I https://social.msdn.microsoft.com/Forums/vstudio/en-US/c95ba61b-78d3-462f-b09f-cd0571ffd22d/how-do-you-catch-exceptions-in-threaded-console-application?forum=csharpgeneral found out that if your application is a GUI application you can add an event handler to Application.ThreadException. However, I don't know how to do this for a command line application. Friday, December 12, 2008 2:18 PM https://bytes.com/topic/c-sharp/answers/233743-catch-all-exceptions-console-based-program Reply | Quote Answers 2 Sign in to vote Generally, you use Application.ThreadException if you developp a winform application.For global exception handling the framework provide the AppDomain.UnHandledException however you can't prevent the application to close error handling on this event. It could be usefull for log purpose.I agree the main thread can't catch this exception, but if you add a try/catch inside the method called by the worker thread, it should prevent your application shutdown. However you have to add a try/catch in every method used by a thread.A solution is to use a BackgroundWorker. With the RunWorkerCompleted event you can check if an error has c# error handling been raised :void bgw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e){ if (e.Error != null) Console.WriteLine("Exception: " + e.Error.ToString()); else Console.WriteLine("End " + e.Result); } Marked as answer by Cebert Friday, December 12, 2008 5:31 PM Friday, December 12, 2008 4:11 PM Reply | Quote 0 Sign in to vote The 'Application ' class is a part of 'System.Windows.Forms' namespace Go to Solution explorer and Right-Click Refrences in your console application A box will pop-up and...... then add System.Windows.Form namespace.Now on the code window use it as Using System.Windows.Forms; (I hope you know how to to this ;) )Now you can use the Application.ThreadException.prs Marked as answer by Cebert Friday, December 12, 2008 2:37 PM Unmarked as answer by Cebert Friday, December 12, 2008 3:34 PM Marked as answer by Cebert Friday, December 12, 2008 5:30 PM Friday, December 12, 2008 2:25 PM Reply | Quote All replies 0 Sign in to vote The 'Application ' class is a part of 'System.Windows.Forms' namespace Go to Solution explorer and Right-Click Refrences in your console application A box will pop-up and...... then add System.Windows.Form namespace.Now on the code window use it as Using System.Windows.Forms; (I hope you know how to to this ;) )Now you can use the Application.ThreadException.prs Marked as answer

Catch All Exceptions for Console Based Program P: n/a Simon Johnson Recently, a thread appeared which asked how to create a "catch all" method for when an exception occurs within a program. The solution given only works for Windows Forms applications, as far as i can tell, is it possible to do the same with a console application? Simon. Nov 15 '05 #1 Post Reply Share this Question 5 Replies P: n/a Morten Wennevik put all code in Main() inside a try/catch(/finally) block. Main is where your program starts and any exception not caught elsewhere in your code will end up in main before your program crashes. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/ Nov 15 '05 #2 P: n/a Nicholas Paldino [.NET/C# MVP] Morten, That's not completely true. You can have multiple threads in a console application, and if an exception is thrown on one of those threads, then you will not catch it by wrapping the code in a try/catch block. Take for example the following code: static void Main(string[] args) { try { // Create a thread. Thread pobjThread = new Thread(new ThreadStart(DoSomething)); // Start the thread. pobjThread.Start(); // Wait five seconds. Thread.Sleep(5000); } catch (Exception e) { Console.WriteLine("Exception on Main thread:") Console.WriteLine(e); } // Get out. return; } private static void DoSomething() { // Throw an exception. throw new Exception(); } This will crash and not be caught by the catch block. Rather, you need to attach to the UnhandledException event on the current AppDomain, like this: static void Main(string[] args) { // Wire up an event handler for unhandled exceptions. AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(UnhandledException) ; try { // Create a thread. Thread pobjThread = new Thread(new ThreadStart(DoSomething)); // Start the thread. pobjThread.Start(); // Wait five seconds. Thread.Sleep(5000); } catch (Exception e) { Console.WriteLine(e); } // Get out. return; } private static void UnhandledException(object sender, UnhandledExceptionEventArgs e) { // Write the exception. Console.WriteLine("AppDomain Unhandled Exception Event Handler:"); Console.WriteLine(e.ExceptionObject); } private static void DoSomething() { // Throw an exception. throw new Exception(); } } Hope this helps. -- - Nicholas Paldino [.NET/C# MVP] - mv*@spam.guard.caspershouse.com "Morten Wennevik"
