silverlight - Check if file exists in folder in c# -

-

I'm moving files from the source folder to the destination folder. Before transferring files, I am checking that the directory is OK or not. This issue is with my second investigation, where I have to ensure that the folder is not empty before running files, but it is not giving me the correct result.

String SourceFolder = (twitterDO.Path + "\\" + msgDate.Year.ToString () + "\\" + msgDate.Month.ToString () + "\\" + msgDate.Day.ToString () + "_Temp" ).To change("\\", @"\"); String Destination = Folder = (twitterDO.Path + "\\" + msgDate.Year.ToString () + "\\" + msgDate.Month.ToString () + "\\" + msgDate.Day.ToString ()). Change ("\\", @ "\"); String pattern = "* .txt"; {Directory.Exists (sourceFolder) {if (File.Exists (pattern)} {foreach (new directoryInfo (sourceFolder) .GetFiles (pattern)} {file.MoveTo (Path.Combine (destinationFolder, file.Name)) ; }} If (Directory.GetFiles (sourceFolder). Length == 0) // before making sure that the Temp folder is empty. Directory. Delete (sourcefolder, true); // Delete the template folder after moving all the contents.}}

I know that I'm making a small mistake but I'm not sure what this is. The following is a screenshot of the result that I got in the immediate window.

There is some redundancy in your current code. Starting with If-check, here's how I will give it: 

  var source Directory = new DirectoryInfo (sourceFolder); // Remember this, if (sourceDirectory.Exists) find the files in the {// directory, if no one is found, then empty range will be (source.directory.GetFiles (pattern) in the source file {file.MoveTo (Path.Combine) (DestinationFolder, file.Name)); } // Check the directory again for any remaining file (SourceDirectory.GetFiles (pattern). Length == 0) // Before ensuring that the Temp folder is empty, sourceDirectory.Delete (); // Delete the template folder after moving all the contents}   
 As a small display improvement, you can use the  sourceDirectory.GetFiles ()  to  sourceDirectory .EnumerateFiles ()  with - loop This will allow them to start walking because they find the method, not after all they are found.

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

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
