How do I regex a string

Question

0.00/5 (No votes)

See more:

I have a json object where one of the parameters is as below

"https://d1swzmic55peuz.cloudfront.net/7.0.1-5xTesi.101/",

or

"https://d1swzmic44peuz.cloudfront.net/7.0.0-bathrolls.103/"

From all the above I need someting like this 7.0.1.101 or
7.0.0.103

What I have tried:

I tried using subtring to remove the text prior to / and then regex but did not manage to filter out the value.

C#

Configuration resource = JsonConvert.DeserializeObject<configuration>(content);
string[] line = resource.ResourceRoot.Split('/');
var regex = new Regex(@"[\d\.]"); var matches = regex.Matches(line[3]);
string version = string.Empty;
foreach (Match match in matches)
{ 
     version = string.Join(version, match);
}

Try this:

C#

string reg = @"(?<=https://.*?/)(\d+\.\d+\.\d+)(?:[^\.]+?)(\.\d+)";
string inp = @"https://d1swzmic55peuz.cloudfront.net/7.0.1-5xTesi.101/";
Match m = Regex.Match(inp, reg);
if (m.Success && m.Groups.Count == 3)
    {
    Console.WriteLine($"{m.Groups[1].Value}{m.Groups[2].Value}");
    }

If you are going to use Regular expressions, get a copy of Expresso[^] - it's free, and it examines and generates Regular expressions.
