There is no problem in testing on the local machine, but an exception is thrown on another computer. This is the most troublesome thing. There is no reason for this at a time, and it cannot be reproduced on the local machine.

Now, we finally find a perfect solution. Add the following code to the Program. cs class:

Static void Main () {Application. threadException + = new System. threading. threadExceptionEventHandler (Application_ThreadException); Application. run (new FrmMain ();} static void Application_ThreadException (object sender, System. threading. threadExceptionEventArgs e) {Exception ex = e. exception; Collect. DX. command. logHelper. logger. error (ex. innerException. toString (); // log // perform some extremely simple operations on MessageBox to record exception information. show (ex. message + Environment. newLine + ex. innerException. toString (), "severe error", MessageBoxButtons. OK, MessageBoxIcon. error); Application. exit ();}

Now the error information is clear at a glance
