How else to pull out the value c #?

Question

C++ / C#

At the moment I'm pulling it like this:

string str = "https://www.site.com/bed/v4/6790244565673643270";

string str = "https://www.site.com/@bed/mp4/6790244565673643270";

var result = str.Split('/')[5];  //->6790244565673643270

How can I get it with regexp ?

Answer 1

var result = Regex.Match(str, @"/(\d+)$").Groups[1];
