@Monty: Hmmm. Well I never know the type, as it was a custom class coming in as “T”, so I don’t know if IList would have worked either. Ah well, past that now, thanks for your comments for the next intrepid adventures to come stumbling by here…. =)

@Monty: Yeah you’d probably have to use & lt; without the space to make that work as proper < and >.

WordPress has just taken out my type parameters, trying again:

if (obj is IList[String])

Instead of [, use angle brackets, you know what I mean

if (obj is IList) will call System.Collections.IList and NOT System.Collections.Generic.IList, because you’ll need to provide the type parameter for the generic, i.e.

if (obj is IList)

If that makes sense?
