Question

I have a function that get’s an exception (ex) and retrieves it’s details and then saves them into DB .

        public static void NewLog(Exception ex, HowToLog option)
    {
        // retrive details of exception
        System.Diagnostics.StackTrace trace = new System.Diagnostics.StackTrace(ex, true);
        string PageName = trace.GetFrame(trace.FrameCount - 1).GetFileName();
        PageName = PageName.Substring(PageName.LastIndexOf("\\") + 1);
....
}

this works in local but on host when an error happens and this function tries to save it into DB an exception ” object refrence not set to an object ” on code below :

PageName = PageName.Substring(PageName.LastIndexOf("\\") + 1);

Answer 1

Looks like PageName was null..
