hi - I'm using VS2010 and .net 4.0 and for program reasons can't upgrade to 4.5. I'm trying to open and read the contents of a zip file so that I can create a data set internal to my program (ie I have no need to create the rest of the zip operation of placing unzipped files somewhere.) I've looked at the Microsoft example code in their Package class that deals with zips and there is reference to an attribute that's not explained. specifically, in the foreach statement to get relationships, the line reads"\
"foreach ( PackageRelationship relationship in documentPart.GetRelationshipByType(ResourceRelationshipType))
the ResourceRelationshipType is undefined if I compile as is. the method is calling for a string, but I don't know where to find the ResourceRelationshipTypes list.
