Problem deleting Directory - access denied

Question

I am copying Windows directory from C: drive to E: drive. When we try to delete this directory from C# application then application throws Access denied file exception. If we try to delete it manually then it gets deleted successfully.

Hi! have you look at the following thread... http://www.codeproject.com/Questions/296249/Visual-Studio-Access-Denied-Errors

Actually I've just had one more thought. The GAC32 and GAC64 directories are of course the 'Global Assembly Caches' for 32 and 64 bit .NET applications. These will contain amongst other things the dlls for the .NET framework classes. So I'd guess that the CLR probably locks them when it loads framework dlls into the current process space. If that's the case you'd get an access denied exception because another process is using the directory. However deleting them manually wouldn't be a problem because the CLR wouldn't be running at that time.

I'm out of ideas in that case :( Wait and see if anyone else has a thought on it.

I have already tried this. But same exception throws by application.

Ah that might be the problem - you're not allowed to delete the application's current working directory. Check out the possible exceptions list in this link: http://msdn.microsoft.com/en-us/library/62t64db3(v=vs.110).aspx

My created application delete all files from that Windows directory. Only remaining assembly directory and in that directory contain GAC32 and GAC64 directory. When application delete this directory then we get Access denied exception.

Are you sure that the directory is empty when you attempt to delete it? Possibly there's a hidden or system file in there.

Yes I have run it as administrator. It gives permission to delete manually for standard user. But does not allow from C# application.

Have you tried 'Run as administrator' ?
