c# - interlock vs mutex, scale-up issues -


I am facing a problem, that I have a C # (.NET) object between some threads. Threads (TCP / IP Connection) can be transformed with others, using the asynchronous framework.

Sequence:

Threads (Waiting for connection) -> Asynchronous Callback -> Some Thread-Safe -> Reach On Shared Object -> Some Thread-Safe

1. Solution Mute X: 

  Object Shared Object = New Object (); Mutus object mute x = new mute x (); Zero thread clack () {object object = new object (); // Some Resource objectMutex.lock (); // If necessary, share object with new object // here very little processing objectMutex.unlock (); // some processing}

embrace 2 solution 

  object share object = new object (); SharedObject = 0; Zero thread clack () {object object = new object (); // Some processing // Poll until we are locked (1 ==) while locking. Exchange (Referral using SheareAbject, 1) // If necessary, share the exchange with new object. There is very little processing in Interlock Exchange (rear using ShearAbject, 0); // free lock} // some processing}

What is fast and what's the better size?

I hope the second solution is not as fast as possible, the second solution for multiple thread polling at the same time can be a random time, so that the time of the voting process is not over. If there is a need to take action on many TCP / IP connections in the past, the first solution is clear to me as I do very little processing in the lock section regarding TCP / IP processing, will there be a staple-up-special ?

How to create an object while initializing the thread () function.

In my C ++ background I always use memory-pool in such a situation, because I have to use safe net is a quick way to create a new object or the .NET platform is good performance in this area Does.

Best regards,

second The way it works, the way it appears, if the lock was not achieved, then you are going out, leaving an important part of your code.

Mutex approach is very easy to understand and I did not have any display problem with it.

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...
