When I target strings such as:
648.1-9999-110.700/2002
with a regex such as:
"\\s{1}\\d{3}[.]\\d{1}[-]\\d{4}[-]\\d{3}[.]\\d{3}[/]"
or
"\\s{1}\\d{3}[.]\\d{1}[-]\\d{4}[-]\\d{3}[.]\\d{3}."
I get a 'cannot open file exception.'
If I remove [/] or the '.' from the regexes above, the substring up to the '/' is found and the program doesn't crash.
I'm writing in C# (on .NET obviously)
Is this a common issue?
