asp.net mvc - MultiSelectList problem, getting right type -

-

I'm having trouble with the selected getting items in a multiple selection

I have done this: 

  BookingObject bo = _bs.GetBookingObjects (bookingobjectID.Value). FirstOrDefault (); Bo.BookingViews.Load (); MultiSelectList BookingViewsBookingObjects = new MultiSelectList (_bvs.GetBookingViews (), "BookingViewID", "BookingViewName", (IEnumerable & LT; BookingView & gt;) bo.BookingViews.ToList ());

BookingViews & lt; -> BookingViewsBookingObjects & lt; -> BookingObjects

Many of this make many connections. _bvs.GetBookingViews () IQueryable returns BookingView, and I can not seem to get the item selected bo.BookingViews.

What can be missing here? Am I using the wrong type?

Perhaps you will send real-selected value in the last parameter IEnumerable & lt; Object & gt; as IEnumerable & lt; BookingView & gt; instead of "BookingViewID", it is a IEnumerable & lt; Int & gt; if BookingViewID something like integer,: 

  MultiSelectList BookingViewsBookingObjects = new MultiSelectList (_bvs.GetBookingViews (), "BookingViewID", "BookingViewName", (IEnumerable & LT; integer & Gt;) Bow.BuckingView Select (a => a.BookingViewID) .Oolist ());

Edit: Full Code

Setup Data (Controller / ViewModel) :. 

  from the list & lt; KeyValuePair & LT; Integer, string & gt; & Gt; List = new list & lt; KeyvaluePair & lt; Int, string & gt; & Gt; () ;; List Add (new keypair & lt; int, string & gt; (1, "value1")); List Add (new keypair & lt; int, string & gt; (2, "value2"); List Add (new keychair & lt; int, string & gt; (3, "value 3")); List Add (new keypad & lt; int, string & gt; (4, "value 4")); & Lt; Integer & gt; Selected = new list & lt; Int & gt; {1,2}; SeeData ["Multi"] = New Multi Sealist (List F. Incommentable (), "Key", "Value", selected);

(View): 

  & lt;% = HTML.ListBox (See "Multi Silackt", "as multi Sillist" [%] "%".

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
