.net - CMD Commands won't run in C# -

-

I am trying to run the following: 

  string command = @ " C: \ user \ some \ documents \ generated_files \ r ++ + "+ folder"; System.Diagnostics.Process.Start ("CMD.exe", "/ K Path C: \\ Program Files \ \ R3.1.1 \\ bin;% path% "); System.Diagnostics.Process.Start (" CMD.exe "," / K "+ command);   
 when I execute it, then nothing happens, does anyone know why? If I try,  
  System.Diagno Stics.Process.Start ("CMD.exe", "/ K MD test");   
 This works fine: s  
 E: Some additional information , The first command is setting the path, so that the router can be called by typing the router. Besides, these two commands work when I do them in normal CMD interface.   
 
 
 Prepare a batch file and execute it using  
  (StreamWriter sw = new StreamWriter ("runcript. cmd ", incorrect)) {sw.WriteLine (@" PATH C: \ Program Fi les \ R \ R-3.1 1 \ bin;% Path% "); Sw.WriteLine (@" RuPut C: \ Users \ Any \ Documents \ generated_files \ ". + + +" + + "+ + Folder);} System.Diagnostics.Process Start ("CMD.exe", "/ k runcript.cmd");   
 Believes that you have given permission to read / write to the current directory. > 
  string path = environment can be changed to more suitable condition by using the gatefolder path (environment specialfolder.appplicationdata); string file cmd = path. Using Bain (path, "Rnskript. Cmd"); (StreamWriter sw = new streamers (file CMD, wrong) ....

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
