Let's say I had a 'Master' collection that contained a computername property and dozens of other properties. Then let's say I had a 'transaction' collection that contained a computername property and dozens of other properties.
I want to remove all instances in the 'Master' collection where the computername matches one that exists in the 'transaction' collection. (For this comparison I dont care about the other properties) All 'Master' collection properties for the remaining instances need to be preserved.
I have tried some nasty coding loops to achieve this but im wondering what would be the most efficient way of coding this?
