Иногда возникает потребность получить route-параметры для строки URL.

Для этого необходимо создать экземпляр RouteData из URL.

RouteInfo Class:

public class RouteInfo  
{  
    public RouteData RouteData { get; private set; }  
  
    public RouteInfo(RouteData data)  
    {  
        RouteData = data;  
    }  
  
    public RouteInfo(Uri uri, string applicationPath)  
    {  
        RouteData = RouteTable.Routes.GetRouteData(new InternalHttpContext(uri, applicationPath));  
    }  
  
    private class InternalHttpContext : HttpContextBase  
    {  
        private readonly HttpRequestBase _request;  
  
        public InternalHttpContext(Uri uri, string applicationPath)  
        {  
            _request = new InternalRequestContext(uri, applicationPath);  
        }  
  
        public override HttpRequestBase Request { get { return _request; } }  
    }  
  
    private class InternalRequestContext : HttpRequestBase  
    {  
        private readonly string _appRelativePath;  
        private readonly string _pathInfo;  
  
        public InternalRequestContext(Uri uri, string applicationPath)  
        {  
            _pathInfo = uri.Query;  
  
            if (String.IsNullOrEmpty(applicationPath) || !uri.AbsolutePath.StartsWith(applicationPath, StringComparison.OrdinalIgnoreCase))  
                _appRelativePath = uri.AbsolutePath.Substring(applicationPath.Length);  
            else  
                _appRelativePath = uri.AbsolutePath;  
        }  
  
        public override string AppRelativeCurrentExecutionFilePath { get { return String.Concat("~", _appRelativePath); } }  
        public override string PathInfo { get { return _pathInfo; } }  
    }  
}  

Пример использования:

Uri uri = new Uri("http://www.yoursite.com/somepage");  
RouteInfo routeInfo = new RouteInfo(uri, HttpContext.Current.Request.ApplicationPath);  
// Here it is...  
RouteData routeData = routeInfo.RouteData;
