Regular Expression to parse string url links

Question

I am looking for a way to parse url link into following segments without using System.Uri

/Default.aspx/123/test?var1=val1

I need to break down this url link into values:

File
PathInfo
Querystring

possible duplicate of regular expression for url

Here's one:

string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)"

it is a bad practice just posting links. If the link broke your answer says nothing

fair enough. but you'd get the same answer by googling "regular expression url", to take credit for their work seems ...wrong.

Here is my code:

   var match = Regex.Match(internalUrl,
                            @"^\/([\w|\/|\-|\,|\s]+)\.([a-zA-Z]{2,5})([\w|\/|\-|\,|\s]*)\??(.*)",
                            RegexOptions.IgnoreCase | RegexOptions.Singleline |
                            RegexOptions.CultureInvariant | RegexOptions.Compiled);
    if (match.Success)
    {
        var filePath = match.Groups[1].Value;
        var fileExtention = match.Groups[2].Value;
        var pathInfo = match.Groups[3].Value;
        var queryString = match.Groups[4].Value;

        log.Debug("FilePath: " + filePath);
        log.Debug("FileExtention: " + fileExtention);
        log.Debug("PathInfo: " + pathInfo);
        log.Debug("QueryString: " + queryString);
    }

string pattern= "\b(?<protocol>https?|ftp|gopher|telnet|file|notes|ms-help)://(?<domain>[-A-Z0-9.]+)(?<file>/[-A-Z0-9+&@#/%=~_|!:,.;]*)?(?<parameters>\?[-A-Z0-9+&@#/%=~_|!:,.;]*)?"

This will generate named groups check for for what you want to extract
