I need regex to validate path like
/addd/dddd
aaaa/bbbb/
a1233/dddd
but not
#ddd/aaaa
or any other symbol,how should I do that?
Try with this one(considering only aaa can not be a path, if so, add it with pipe):
^((?:/[a-zA-Z0-9]+)+/?|/?(?:[a-zA-Z0-9]+/)+)[a-zA-Z0-9]*$
(?:/[a-zA-Z0-9]+)+/? is matching paths like aa/aa/ and /?(?:[a-zA-Z0-9]+/)+ is matching directories like /aa/aa. And [a-zA-Z0-9]* is checking for additional names when the directory format is aa/aa.

Checked a number of places, but can't find a coherent concise definition of materialize in the sense of a "materialized system.double type" -- what is the word materialized signifying?
It's a fancy way of saying "deserialized". Read this MSDN page about EF which doesn't actually give a definition but it uses the word enough to clarify things through it's context such as...
Query results are materialized into objects that the Entity Framework manages.

What is the formula for converting UPC-E barcodes to UPC-A barcodes? Better yet would be some C# code, C#esque pseudocode, or even just in an "English" expository way.
Ctrl+F for "Converting UPC-A to UPC-E" at http://www.taltech.com/barcodesoftware/symbologies/upc . It explains all the cases in a better format than I can paste here.
