Delete Access Denied!!

I'm using the codes below trying to delete files and I got an error that say I'm trying to delete a file that still being used by another process. Please help me how to check which files are being use and skip over that and delete everything else. Here is my code so far, thanks in advance.

foreach (DirectoryInfo Dinfo in dirInfo.GetDirectories("*"))

{

foreach (FileInfo file in Dinfo.GetFiles("*.*"))

{

try

{

file.Delete();

}

catch (FileNotFoundException e)

{

Console.Write(e.FileName.ToString());

}

}

}

Thanks

Jason

Yes, I try that and it doesn't delete the files in the "Temporary Internet Files" folder.

Try:

List<FileInfo> MyFileList = new List<FileInfo>;

foreach (DirectoryInfo Dinfo in dirInfo.GetDirectories("*"))

                 foreach (FileInfo file in Dinfo.GetFiles("*.*"))

                 {

                    try

                    {

                      MyFileList.Add(file);

                    }

                   catch (FileNotFoundException e)

                    {

                        Console.Write(e.FileName.ToString());

                     }

                  }

foreach(FileInfo f in MyFileList) f.Delete();

MyFileList.Clear();

Maybe the first bucle is lock its contains files.

Thanks Mark, I swear I changed it before to IOException! Think the topic title was stuck in my mind but the fingers were typing something else. So yes, you can implement both, the IOException and the UnAuthorizedException, in case you get the security error too

same code would apply as you have done, except point to the Temp internet files folder and delete the files it can delete. So are you saying you did this and its not deleting it
Polleveys
some files you cannot delete in that folder as its a Windows folder and it manages it in its own way. Some files maybe in use, some are system files which Windows will deny access to
BillyB

it wouldnt be a fileNotFound exception but rather an UnAuthorizedException in the catch block

so overall the code:

foreach(DirectoryInfo dInfo in dirInfo.GetDirectories("*"))

{

   string[] theFiles = System.IO.Directory.GetFiles(dInfo.FullName);

   foreach(string currentFile in theFiles)

   {

      try

      {

         System.IO.File.Delete(currentFile);

      }

      catch (UnAuthorizedAccessException ex)

      {

         //handle if you like

      }

      catch (IOException ex)

      {

         //handle if you like

      }

   }

Hi,

Thanks for the info......but I have some .wma in the "Temporary Internet Files" folder and it not being use by any process nor it a Window file, it just some file downloaded from the internet. I can right click and delete it, but I want to write a C# code that will delete those files in my "Temporary Internet Files" folder. Can I do that

Trying to delete a file which is in use will cause an IOException which you should catch. I don't think there's any way to find out whether a file is in use other than trying to do something to it and catching the exception.
