How do I extract PART of a specific string from a huge chunk of ugly strings?

String:

https://company.zendesk.com/api/v2/tickets/33126.json

I need the number 33126.

What’s the optimal way to extract this number?

Answer 1

Since that is a path/url, use Path.GetFileNameWithoutExtension:

string name = Path.GetFileNameWithoutExtension(path);

I would prefer Path, but if you want to use the Uri class instead, you can also use this:

Uri uri = new Uri("https://company.zendesk.com/api/v2/tickets/33126.json");
string lastSegment = uri.Segments.Last();
string name = lastSegment.Substring(0, lastSegment.IndexOf('.'));
