Question

I’m trying to figure out is it possible and how to implement this functionality using Enterprise Library Logging.

In my current code I’m handling exceptions like this:

exceptionManager.HandleException(ex, "LogException");

What I want is to log this exception, but gather additional context information, for example assembly version, what I need to extend \ implement to log this additional context information?

Answer 1

Probably the easiest way is to use the Data property of the exception to attach your additional context information. Enterprise Library will then map all of the Data elements to Extended Properties.

try
{
    DoSomething();
}
catch (Exception ex)
{
    ex.Data["ExecutingAssembly"] = Assembly.GetExecutingAssembly().FullName;

    bool rethrow = exceptionManager.HandleException(ex, "LogException");

    if (rethrow)
    {
        throw;
    }
}

Then make sure the log template has the extended properties set to log:

Extended Properties: {dictionary({key} - {value}
