Get individual query parameters from Uri [duplicate]

Answer 1

I had to do this for a modern windows app. I used the following:

public static class UriExtensions
{
    private static readonly Regex _regex = new Regex(@"[?&](\w[\w.]*)=([^?&]+)");

    public static IReadOnlyDictionary ParseQueryString(this Uri uri)
    {
        var match = _regex.Match(uri.PathAndQuery);
        var paramaters = new Dictionary();
        while (match.Success)
        {
            paramaters.Add(match.Groups[1].Value, match.Groups[2].Value);
            match = match.NextMatch();
        }
        return paramaters;
    }
}
