java - The value of the local variable word is not used -

-

I have a way in which a scanner is in the form of a parameter, the purpose of the method is to calculate the number of words in a file Do it and have to return that number. Here's the method: 

  Public Static Inter WordCount (Scanner InputFile) FontNoteFound Actions {int wordCount = 0; While (inputFile.hasNext ()) {string word = inputFile.next (); Word count ++; } Return password; }   
 The method works fine, but I "do not use the value of the local variable" warning which I would like to get rid of I understand why I am getting a warning, however, as far as I know, I need  
  string word = inputFile.next ();   
 To move the pointer through the file. I can suppress the warning, though, I think that I am probably trying to do. I can use only the scanner class to read the file.   
 
 
 What you're doing is okay, but warnings are given because you only  the word < / Code> and can not read it anyway, instead of just saving the results, leaving the assignment and just try using  inputFile.next () .

I know that the query is quite messy Edit: I realized that there are two questions to be needed, so I have strictly modified a question question table data tables ss_users user_id FIRST_NAME LAST_NAME admin_level user_approved 1 Nick Jones 0 1 2 Johnny Rocket 0 1 table ss_user_profile_status user_id photo_uploaded 1 1 2 1 table ss_user_photos selected user_id file name photo_id 1 1 photo_1 .jpg 1 2 2 photo_2.jpg 0 3 2 photo_2.jpg 1 table ss_general user_id city state zip neighborhood 1 Baltimore maryland 00125 hamsterdam 2 Lekland My 11542 treemont table ss_languages ​​user_id French German Italian Spanish 1 0 1 0 1 2 0 1 1 Table ss_experience Waldorf Kumon homeschooling user_id 1 0 1 0 2 0 0 1 My current The result is that all users, which should not be the case: ...

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...
