Getting the Id of an error in Elmah after calling .Raise()

Question

I\'m working on an MVC3 application and I\'m using Elmah to handle my error logging. What I want in my application is to carry the Elmah Id onto the custom error page as I will

Answer 1

The solution above only works only if there is a Session object (website scenario). We needed it to work in an Azure WorkerRole, or a console / desktop app type setup. This solution will also work for web and save some session memory. There isn't a perfect solution, but one that worked for us to be able to log the error and retrieve the stored ID AND fire off an email is to:

1. Store the error using ErrorLog.Log(error) (see: Using ELMAH in a console application)
2. Raise the error skipping the logging (SQL or otherwise)

For the second part, we used the implementation of ElmahExtension given here: https://stackoverflow.com/a/2473580/476400

and REMOVED the following lines adding the logging:

(ErrorLog as IHttpModule).Init(httpApplication);
errorFilter.HookFiltering(ErrorLog);  //removed!

The entire call from our client code looks like this:

ErrorLog errorLog = ErrorLog.GetDefault(null);
errorLog.ApplicationName = "YourAppName";
Error error = new Error(ex);
string errorResult = errorLog.Log(error);
Guid errorId = new Guid(errorResult);

ex.LogToElmah(); //this is just going to send the email

You might want to call that extention method something else, like RaiseToElmahNoStorage(), or something to indicate it is skipping the storage component.
