It just passes an else and and catch.  I posted the rough draft of the
test method here if you wish to see in more detail
http://joeswammi.com/projects/InitializeDB.txt

That test method above is a quickly modified version of an another
method that actually passes out a StringCollection.  Sorry, I haven't
modified the code to be more reflective of what it is actually doing.
But I believe I have captured the times correctly.  And it seems to
successfully create the semantic network of the predicate files within
the PythonEngine.


>And I'm having trouble parsing "but things slow down significantly
when I try to enumerate the StringCollection into a PythonEngine".  Is
this just doing a set variable, or are you looping over the collection
and doing a set variable one at a time?

Yes, here is a test method I used using unpp()
http://joeswammi.com/projects/load_predicate_files.txt

Ideally, this C# load_predicate_files() method would actually create
the semantic dictionaries instead of passing the StringCollection
nodes to just unpp().

I did try a more static approach...

But I didn't like the results, could be my own fault though.  It was
very slow esp. when it reached around 3000 predicate lines from the
StringCollection.
