asp.net - Auto Suggested Text Box with concatenated string with LINQ to SQL -

-

I'm creating a text box I've suggested, so it works well, it only suggests the first name , But I want to suggest it the full name (first and last name which tells two different columns). Take a look at the following code behind expected work: 

  & lt; System.Web.Services.WebMethod () & gt; _ Public Shared Function GetNames (ByVal prefixText as string, counting as ByVal integer) String () DD as new dimotattext () Dimension db.Students.Where (function) function (n) n. FirstName). Select (function (n) n.FirstName). (Counting) .Ore end function

Here's the mark-up:

I wrote the following code to get the text box to be a full name, but it does not work: 

  dim query = (from S in D.B.Standt _ where s.FirstName.StartsWith (prefixText) _Server s.FirstName_ Select {new name = s.FirstName & amp; "" & L.ListName} ") with new one. Take it (count) .Oere return query

When I create this project, it says that the value of type '1-dimensional array (line 50)' string 'Can not be converted to a 1-dimensional array' because 'line 50' is not derived from 'string')

Annoboy suggests, please comment. Thanks.

Do not create a new anonymous object with a name attribute that is a string Return, just return the string: 

  slow query = (s from DB.Stendent_s_ where s.firstname. Start (prefix text) _server s.firstname_. Firstname & amp; "" & amp; s.lastname). (Calculation) .oor

-
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.
