c# - How is.NET's NetworkStream delimiting multiple messages in the same packet? -


So I have been entrusted with the task of creating a tool for our QA department which can read the packet from the wire and Can rejoin correctly (they do not rely on our logs ... long story).

The NCT's TCPLstner and TCP Client Classes are being used to communicate the application I want to communicate. Stopped the packet is not a problem (I'm using). However, adding correctly packet to application level messages is proving to be a bit trickier.

In some packets there is a message ending and the next message begins and they tell me how 'networkstream object' in NTT tells us where an application level message ends and the other starts.

I have been successful in determining whether the TCP header "PSH" (push) flag will be turned on in an application level message in any packet. But I do not know how .NET knows what's inside that packet at the end of the message.

The data of a packet can look like this: 

  / & lt; Message & gt; & Lt; Message & gt; System = http: // blah

from the header only & lt; / Messages & gt; And store until the rest is completed until the rest of the message is complete?

There is no IP level flag set for fragmentation, and there is no knowledge of .NET sockets. Application level protocols, I am incredibly disturbed. Any insights will be appreciated.

The stream does not know the end of something - this should be part of the application protocol.

In the networkstream , nothing is included to convert the data to an object. What do you think of this? Does the network manage the code to use the stream? Are you probably doing some form of XML deserialization, and the read code automatically stops when it reaches the closing tag?

Actually:

  • If your protocol has no message delimiter or length prefix, it should be
  • networkstream There is no possibility of cleverness of yourself - but if you can tell us what you are watching, we may be probably what's happening.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
