I did installation to my c# app. When I finished installing it.
I started the program then this message came out?
Microsoft .net framework
unhanded exception has occurred in your application .If you click continue,the application will ignore this error and attempt to continue. if you click quit ,the application will close immediately
Index was outside the bounds of the arry.

1 solution

This means that your application tries to use an array at an index that is outside the bounds of said array. This results in an exception that your application didn't handle.

From what we see here, it's impossible to investigate the cause of the problem. Add a global exception handler[^] to get more information on where the error occured.

I tried this one


static void Main()





//Application.Run(new MainForm());

Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException);

AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

Application.Run(new MainForm());


static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)


MessageBox.Show("CurrentDomain_UnhandledException: " + e.ExceptionObject.ToString());


static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)


MessageBox.Show("Application_ThreadException: " + e.Exception.Message);


and it works

Thanks .

And by "it works", do you mean that you now know where the error occured and that you were able to fix it? Or do you simply not observe an error message anymore?

In the latter case, this is not a solution. You have to investigate the error and fix it. Otherwise you're asking for doomsday to happen.
