Perhaps you could select one specific standard port as a "management" port; computer B could open a connection to the standard port, and computer A would send back a list of its own open ports. Adam Maras | Software Developer Microsoft Certified Professional Developer

Then the issue is CAN _memberString be modified in mid-copy, under any circumstances? Consider that... 1) Strings are immutable, at least at the level of C# code. 2) _memberString is actually a reference to a string, not the string itself. References are N bytes (can't remember what N is). Perhaps it is possible that while those N bytes are being copied, the copy could be interrupted and the N bytes overwritten by a new value, so that the reference copied to s is corrupted. Like the other guy said, better safe than sorry.

Yes, and if you think it is weird then you should read the credits on any major movie - especially a contemoporary one that uses contemporary music rather than its own score to see them racking up on other people's copyright (and then crediting them). Or, you could look at any compilation album. If you read the inside of the booklet there will be page(s) of copyright notices for each of the tracks, but there will still be a copyright on the compilation itself.

It's not that critical, just a "nice to have" for my app. Besides, if it was that easy, it seems like there would already be a free code library available for this. Heck, my boss may even be willing to pay a reasonable price for one.
