Audit.Net，-即使抛出异常，也需要正确的审核

Question

When this method is executed in the Controller:

[Route("deleteIncCloseOut")]
[HttpDelete]
[AuditApi]
public bool deleteIncidentCloseOut(int ID)
{
  try
  {
    using (ESSDataContext ctx = new ESSDataContext())
    {
      ctx.DeleteIncidentCloseOut(ID);
      this.GetCurrentAuditScope().SetCustomField("Dynamic", new { IncidentCloseOutID = ID });
      return true;
    }
  }
  catch (Exception ex)
  {
    log.Error($"{ex.StackTrace}");
    return false;
    throw ex;
  }
}

There is an exception with the stored procedure DeleteIncidentCloseOut(ID) , and so the CustomField of the AuditEvent is not being set. However, the DataProvider's InsertEvent is still being executed.

My problem is that in my InsertEvent I have to populate two tables. One table has a brief description of the audit event, and the other contains the properties and values of the object that is set as the CustomField of the AuditEvent object. In this case, I create a dynamic object with the ID as the property. So, I get an entry in my first table that the IncidentCloseOut has been deleted (but actually it hasn't, since an exception was thrown), but I do not get the ID of the supposedly deleted event in the second table (since there was no CustomField set). So I am getting false auditing information. Preferably, the stored procedure wouldn't throw an exception, but I would like the auditing to be correct, even if an exception is thrown.

How can I rectify/improve this situation?

Just set the custom field before calling the stored procedure that throws the exception:

public bool deleteIncidentCloseOut(int ID)
{
  try
  {
    using (ESSDataContext ctx = new ESSDataContext())
    {
      this.GetCurrentAuditScope().SetCustomField("Dynamic", new { IncidentCloseOutID = ID });
      ctx.DeleteIncidentCloseOut(ID);
      return true;
    }
  }
  catch (Exception ex)
  {
    ...
  }
}
