Hello stackoverflowers,
i couldn't figure the solution out by myself and couldn't find a related answer so i seek your help :)
I'm working in a VB.Net 4.x environment where i usualy have to join windows styled paths from various sources that are very unreliable in its format (leading slashes, ending slashes, sometimes double slashes inside) hence i can't use Path.Join
My next best guess is to regex replace any double occurance of a backward slash with a single one:
\\+
which is too naive, as it also converts a server adress which starts with a leading double backslash.
pseudocode
"\\server123\\a\\b\\\c\\".replace(/\\+/g, "\") -> "\server123\a\b\c"
thats a problem. i want to exclude any leading backslashes from matching. So i though i negative lookahead it:
regex
(?!^\\+)\\+
which would work in my example. But it does not what i want it to do. It matches the second backslash slash and replaces it.
What is wrong with my second regex? how do i negative lookahead something at the start.
Thanks for any explanation and solution
