访问原始TCP数据包有效负载数据 [英] Accessing raw TCP packet payload data
问题描述
大家好，
有没有人知道是否可以使用.NET（C＃）从
a TCP数据包中获取原始有效负载数据确切地说。
我正在编写一个软件，它使用封装在TCP内部的协议与网络的
设备进行通信。协议的结构是这样的，流语义并不真正适合通信; b $ b用于通信;封装数据包的所有数据必须在单个TCP数据包中适合
。我只是希望能够从设备中获取每个TCP数据包的有效负载，
已建立的连接。

Hi All,
Does anyone know if it''s possible to grab the raw payload data from
a TCP packet, using .NET (C# to be exact).
I''m writing a piece of software that communicates to a networked
device using a protocol encapsulated inside TCP. The structure of
the protocol is such that stream semantics aren''t really appropiate
for communication; all the data for an encapsulated packet has to
fit inside a single TCP packet. I just want to be able to pickup
the payload for each TCP packet that comes in from the device, on
the established connection.

如前所述，您可以使用原始套接字等来访问此
信息。然而，我不得不怀疑在这样一个
场景中使用TCP的意义。

As has already been mentioned you can use raw sockets etc to access this
information. I would however have to wonder the point of using TCP in such a
scenario.

鉴于我必须自己重新实现TCP的机制，那么
并不是很重要。如果我可以拿起有效载荷那么
它可能会稍微容错一些而不需要
我的任何额外工作。
我也可以只使用协议的UDP版本 - 无论如何在封装协议中进行
会话注册。
实际上有'封装的
协议中的会话注册以及封装封装的协议。

Given I''d have to re-implement the mechanics of TCP myself, there
isn''t much point at all. If I could just pick up the payloads then
it would have been slightly more error tolerant without requiring
any extra work on my part.
I may as well just use the UDP version of the protocol - there''s
session registration within the encapsulated protocol anyway.
Actually there''s session registration within the encapsulated
protocol and the protocol that the encapsulation is encapsulating.
