c# - Typing variables holding instances of constrained generic classes -

-

I'm just starting to grab with generic and now (AB) using a very intricate section of my code Again (I'm using C # for only a short time, but I am quite experienced in other languages).

I have a heritage structure where my classes extend a base class. I have most of the functionality in the base class but I want to connect these children's classes with the examples of their siblings.

Here is a simplification of some relevant code: 

  class ParentClass & lt; T & gt; Where T: ParentClass & lt; T & gt;, New () {Create Public Static T ({{New T (Return); } Private Object joinItem; Join Public Zero & lt; TJoinee & gt; (TJoinee items) where TJoinee: ParentClass & lt; Tōoinee & gt;, new () {joinItem = item; }} Category ChildOne: ParentClass & lt; ChildOne & gt; {} Class ChildTwo: ParentClass & lt; ChildTwo & gt; {}

In place of this code, I can do something like this: 

  var a = ChildOne.Create (); A.Join (New ChildTwo ());

The problem is that I need to type in the form of the joinItem object when I actually call it ParentClass & lt; Something & gt; Can it write more specific types in joinItem ? Or am I very humiliating the language and should take a completely different approach?

Do you have ParentClass & lt; T & gt; Interface from > which is not dependent on T ? In this way the joining item can be typed in the interface.

It seems that you can do that why you are trying to do this ( ParentClass & lt

if that ParentClass & lt; T & Gt; If there is nothing in the interface, then

is not dependent on T , then T

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.
