Question

I want to know every exceptional situation while it is happened. I think I need to write code in every catch block

1. send email
2. send sms
3. write it to log file

4. write event log
   etc.

   try{
   // do something
   }catch(Exception ex){
   // send me ex…
   }

Is there any easy way to inject catch blocks without writing any code?

PS: While I’m reading the answer’s links, I came across some articles and I want to add quotas to my question.

Exception Handling Best Practices in .NET

Generic Exceptions caught should be published
It really doesn’t matter what you use for logging – log4net, EIF, Event Log, TraceListeners, text files, etc. What’s really important is: if you caught a generic Exception, log it somewhere. But log it only once – often code is ridden with catch blocks that log exceptions and you end up with a huge log, with too much repeated information to be useful.

Answer 1

You could create your own exception class which logs the exception message and/or stack trace. We do this using log4net and it works, but does require consistent implementation. You only really want to do this at a layer or tier boundary, since for most situations if you don’t know how to handle an exception it should just bubble up the call stack.

Something like:

[Serializable]
public class FooException : Exception
{
    // Logger configured for email, file, etc.
    static ILog _log = LogFactory.Create();

    public FooException(string message, Exception innerException)
        : base(message, innerException)
    {
        _log.Error(message, innerException);
    }

    // ...
}

public class FooDataAccess<T> : IFooRepository
{
    public T GetFoo()
    {
        // Consider creating general helper methods with 
        // Action, Func, parameters so that you only have
        // to code the try ... catch block once.
        try
        {              
            // all exceptions caught
        }
        catch (Exception e)
        {
            throw new FooException(Exceptions.GetFooException, e);
        }
    }     
}
