I am trying to parse the digits to store in a variable from a string in VB.NET (would like to also include the decimal point).
Here is an example string: Refund issued for $27.74
As casperOne already pointed out, one example is not sufficient to give a full solution.
The regular expression string could look like
"\\$([0-9]+\\.[0-9]+)"or"Refund issued for \$(?<Value>[0-9]+\.[0-9]+)". The latter being more more restrictive.The second example also uses a named group. This can make it easier to extract the matches after the call to Regex.Match if you have a more complex scenario.
A nice tool to play around with .net style regular expressions is Expresso.
