Hello:
Atatched is a sample test case using regular expressions
that fails in mono (Fedora Core 1) but works fine in .NET.
The problem seems to be in the:
return Regex.Replace(input, g.Value, "$1");
it can be fixed using:
return Regex.Replace(input, g.Value, "$$1");
But as the code works fine in .NET using a single $ i want to
know if it's a mono problem or the double $$ is tyhe correct syntax ??
( For now i will fix my code it using $$ :) )
