Solution 2

Basically, you can't.
If access is denied to a folder, the "AllDirectories" search will terminate and there is no way to "restart" it.
You only option is to fetch the files in a directory manually, then recursively scan all it's subdirectories using a try-catch block to find access problems and ignore those.

is it possible without recursive function?

OriginalGriff 22-Aug-15 5:38am

Yes...but it's not simple - the directory structure is naturally recursive, so you'd have to "emulate" that yourself - recursion is a simpler solution here.

Certainly, there is no "built in" function which will do it for you.

The actual answer was only the first line, access is denied. No matter how much he try, .NET would always return this exception and will continuously say, "Access is denied".

(To OP) Now if you want to piss your users off with an iteration of error pop ups, then go ahead set it to a loop!

Only solution is to ask the user to grant the permission to read and write, by the way which directory you want to write the files or lists to?

OriginalGriff 22-Aug-15 6:54am

Not necessarily.
If he's trying to do this on the root folder of a disk...do you really want the user granting "full access" to the Windows folder?

That depends on user, whether he trusts the developer or not. Simple as that, if user doesn't trust he won't. If he does (most specially if he himself is the user at the moment) then he will so that application continues to function, properly. :-)

Solution 1

C#

foreach (var file in files)
{
    try
    {
        // your code here
    {
    catch
    {
    }
}

No this is not working.
My code is:
foreach (string f in Directory.GetFiles(path,"*.*",SearchOption.AllDirectories))

Rather than searching all directories in one go you're going to have to search recursively, directory by directory, so you can skip the ones you don't have access to.
