ASP.NET / VB / REGEX: Automatically create email links ignoring characters at end

I use the following code to make email addresses links.

input = RegularExpressions.Regex.Replace(input, "(\S+\@\S+\.\S+)", "<a href=""mailto:$1"">$1</a>")

Open in new window


The problem is that periods and commas and single quotes and double quotes mess things up.

Try:

input = RegularExpressions.Regex.Replace(input, "(\S+\@\S+\.[^\s,.""']+)", "<a href=""mailto:$1"">$1</a>")

kaufmed, that fixes this:
xyz@example.com.
and this:
xyz@example.com"

But not this:
"xyz@example.com"

Could you make it work for both the beginning and the end?

Thanks.

Sure, just replace the thing at the front with the thing I change to on the back. In other words:

input = RegularExpressions.Regex.Replace(input, "([^\s@,.""']+\@\S+\.[^\s@,.""']+)", "<a href=""mailto:$1"">$1</a>")
