int LastFwdSlash = URLString.LastIndexOf('/');
String Number = URLString.Substring(LastFwdSlash + 1, URLString.Length);
int Number = int.Parse(URLString);

The other answers using string methods would be correct if this was a simple string, but since this is a URL, you should use the proper class to handle URIs:

var url = new Uri("http://www.testproject.com/tokyo/4");
var lastSegment = url.Segments.Last();

Example of what AD.Net meant:

public string getLastBit(string s) {
    int pos = s.LastIndexOf('/') + 1;
    return s.Substring(pos, s.Length - pos);
}

Returns:

4, 11, 819

When passed in an individual url.

Without using regex, you can find the index of last "/" by using string.LastIndexOf('/') and get the rest by using string.SubString

string myUrl = "http://www.testproject.com/tokyo/4";

string[] parts = myUrl.Split('/');

string itIsFour = parts[parts.Length-1];
