Log4net Causing error

Mar 30, 2016 10:19 AM|david38ni|LINK

I am using Log4Net and have setup it up in the way describe in the site and forums. But I am having a very strange issue in the Ilog it is crashing some methods but not all. The following is an example of a routine that is causing crash. Might I add that it only happens when I call ex.InnerException.ToString()) not when I call ex.ToString()

 /// <summary>
        /// Handles the Click event of the rdSaveApointment control.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The <see cref="EventArgs"/> instance containing the event data.</param>
        protected void rdSaveApointment_Click(object sender, EventArgs e)
        {
            try
            {
                Appointment _appointment = new Appointment();
                int id = Convert.ToInt32(Request.QueryString["id"]);
                _appointment = _dal.GetAppointMentByiD(id, "");

                if (_appointment.TimeCode == null)
                    _appointment.TimeCode = _dal.GetPrefix("Calendar").ToString();

                DateTime startDate = (!rdStarDate.SelectedDate.HasValue || rdStarDate.SelectedDate.Value == new DateTime(1900, 1, 1)) ? DateTime.Today : rdStarDate.SelectedDate.Value;
                DateTime endDate = (!rdEndDate.SelectedDate.HasValue || rdEndDate.SelectedDate.Value == new DateTime(1900, 1, 1)) ? DateTime.Today : rdEndDate.SelectedDate.Value;

                _appointment.CustomerFirstName = txtChrisitanName.Text;
                _appointment.CustomerLastName = txtSurname.Text;
                _appointment.Start = startDate;
                _appointment.End = endDate;
                _appointment.Subject = "OCCUPIED";
                _appointment.isDeleted = false;
                _appointment.notes = txtNotes.Text;
                _appointment.preferedContactNumber = txtContactNum.Text;
                _appointment.mobileNumber = txtMobileNumber.Text;
                _appointment.authUserName = Environment.UserName;
                _appointment.authCreatedDate = DateTime.Now;
                _appointment.Address1 = txtAddress1.Text;
                _appointment.Address2 = txtAddress2.Text;
                _appointment.County = txtCounty.Text;
                _appointment.PostCode = txtPostCode.Text;

                if (_appointment.EntityState == System.Data.EntityState.Detached)
                    _dal.apertureNetEntities.Appointments.AddObject(_appointment);

                _dal.SaveChanges();
                Response.Redirect("default.aspx");
            }
            catch (Exception ex)
            {
                logger.Error("Error in rdSaveAppointment_click function calandar edit.aspx" + ex.InnerException.ToString());
            }
        }

Might I add that it only happens when I call ex.InnerException.ToString()) not when I call ex.ToString()

Most likely the inner exception null.

string inner = string.Empty;
if(ex.InnerException != null)
{
	inner = ex.InnerException.ToString()
}
logger.Error("Error in rdSaveAppointment_click function calandar edit.aspx" + inner);

Also you're ignoring the current exception.

string inner = string.Empty;
if(ex.InnerException != null)
{
	inner = ex.InnerException.ToString()
}
logger.Error("Error in rdSaveAppointment_click function calandar edit.aspx" + ex.Tostring() + " " + inner);

Please see the following reference docs from MSDN.
