Getting all messages from InnerException(s)?

Question

Is there any way to write a LINQ style \"short hand\" code for walking to all levels of InnerException(s) of Exception thrown? I would prefer to write it in place instead of

I don't think so, exception is not an IEnumerable so you can't perform a linq query against one on its own.

An extension method to return the inner exceptions would work like this

public static class ExceptionExtensions
{
    public static IEnumerable InnerExceptions(this Exception exception)
    {
        Exception ex = exception;

        while (ex != null)
        {
            yield return ex;
            ex = ex.InnerException;
        }
    }
}

you could then append all the messages using a linq query like this:

var allMessageText = string.Concat(exception.InnerExceptions().Select(e => e.Message + ","));
