c# - Comparing dates in linq -

-

I would like to query the DB for items equal to or equal to a date.

The date in DB is a time and time of record time.

If the user enters the search string "1/30/2014", then they expect the entries that come at any time of that date. However, nothing is returned once after 12 o'clock.

I know that I could only add one day to the search string, but is this a more appropriate way? 

  if (form ["closed" "] =" ") {datetime d = datetime purse (form [" off ""]); Mark = mark Where (s => gt; s.date_Closed & gt; =); }   
 
 
 You can use to reduce the portion of time: < / P> 
  traces = marks Where (s = & gt; s.date_Closed.Date & lt; = d.Date);   
 In this way you add this day because both  is the date of the date  s is midnight.  
  Update  You can not use LINQ units like  DateTime.Date , you can use this solution:  
 . Where (S = & gt; unit function. TruncateTime (s.date_Closed) & lt; = EntityFunctions.TruncateTime (D))

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
