Manual Elmah logging

Question

how I can use Elmah logger only when I want? I have ErrorsController and I need log it only when excpetion is unknown: Elmah.ErrorSignal.FromCurrentContext().Raise(new Exception(string.Format("{0}, {1}", controller, action), exception)); I didn't implement ElmahAttributes, Elmah added only in web.config. How I can do that? I have idea to use some errorFilter that will filter all incoming errors, but it's not very good, I think. UPD I have add filter that ignores all errors: but it ignores absolutely everything, even that I call to log manually.

Answer 1

I understand why filter ignores error - because when using Elmah.ErrorSignal.FromCurrentContext().Raise() we are "emulate" process of getting error and this errors fall under the filter. Instead of this method we should use Elmah logger method to add error to log: Elmah.ErrorLog.GetDefault(System.Web.HttpContext.Current).Log() This method will add error to log and filter below will ignore all others: After all this I have one question - name tag inside can only be test?
