c# - How to asynchronously run 3 processes, when one returns desired value stop the other two and continue with program? -

-

I have a method that uses the afgh.net.net framework templatematch (similarity to image against another image Check different images against any area of ​​the screen This task can take a long time or can be instantly based on the number of images, the size of the images and the field check.

Only 1 image in the list of images will ever return a match so I would like to test all the images against the screen at the same time and cancel the remaining processes immediately after 1 point of that point is correct Is given and my program runs on its next step.

Now, for example, I'm getting an integer value that depends on the match's right but the concept is always the same. The number of images tested against screenshots. 1 will come true, will not be left Sometimes the returns are correct first and for the second time it corresponds to the template for 30 and 30 images in the list and takes a lot of time compared to 1.

A warning to note about my code which is as follows .. I will not always return an integer, I usually return a boolean value as the image was found, but this code is here The easiest and common principle applies (i.e. if i read the following as my (synchronous) code as follows ... how can i do this asynchronous call what i can do, What is described If possible, please expand your answer as if I want to know that in future I can easily do this type of thing. I understand the concept of async but for some reason my head is absolutely fine The way I want to. 

  Public Zero fight () {var myGuysTurn = WhosTurn (); // Other logic here.} Private Ent WhosTurn () {var whosTurn = 0; Var whosTurnCheck = _templateMatch.Match (_tabula.BattleHeroTurn1 ()); if (whosTurnCheck) {whosTurn = 1; return whosTurn;} wh OsTurnCheck = _templateMatch.Match (_tabula.BattleHeroTurn2 ()); if (whosTurnCheck) {whosTurn = 2; WhosTurn return; WhosTurnCheck = _templateMatch.Match (_tabula.BattleHeroTurn3 ()); If (whosTurnCheck) {whosTurn = 3; WhosTurn return; } Return whosTurn; }    
 
 
 I was using the  task. WaitAny ()  is combined with a  cancellation token . Basically, start each task in parallel and no one is complete. If the whole work was successful, cancel others if not, keep waiting for other tasks to continue.  
 I have changed the  _templateMatch.Match (_tabula.BattleHeroTurnX ())  with a static method for summarizing  with BattleHeroTurnX :  
  Personalized WhosTurn () {// Create a cancellation token. Other threads will be used to inform that they should cancel cancellation immediately Cancel token resource cts = new cancellationTokenSource (); // Collection of works in parallel lists & lt; Work & lt; Int & gt; & Gt; Work = new list & work; Task & lt; Int & gt; & Gt; () {Tasks. Run & lieutenant; Int & gt; (() => {return BattleHortorn 1 (CTS. token) 1: 0;}), action.run < Int & gt; () = & Gt; {Return Bethelhorne Turn 2 (CTS.Token) 2: 0;}), Tasks. Run and lieutenant; Integrated; ((=) = & Gt; {BattleHarrowTiturn3 (CTS.Token) 3: 0;})}; // Wait for any work to be done and if it succeeds, then cancel other tasks and return (work.) (Any)) // // Get the complete completion of the task TaskIndex = Task.WaitAny (tasks.ToArray)); Intel turn = work [fulltask index]. result; If (turn> 0) {cts.Cancel (); Return return; } Taskss.RemoveAt (fullslash index); } // has completed all the tasks, but no Bethelhortienne did not return the correct return; } Static Bull BattleHarator1 (Cancellation Tokens Token) {// Processing images are processed after each, make sure token (Int i = 0; i & lt; i ++) {thread. Sleep (50) has not been canceled; If (token. ICC cancellation request) {return false; }} Be true; } Static Bull BattleHoratronic 2 (Cancellation token token) {// Processing images are processed after each, make sure token (int i = 0; i <10; i ++) {thread. Sleep (70); If (token. ICC cancellation request) {return false; }} Be true; } Static Bull BattleHarator 3 (Cancellation Token Tokens) {// Processing images are processed after each, make sure token (int i = 0; i

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
