I want to get permission to interact with a file.

[Yohan Bischofberger]

Hello, I want to work with a File. I cant get Permission or owner. Im not the owner of the files as i can see in the propertys. The Path of the Files are: %userprofile%\AppData\Local\Temp Here is how i tried to get access owner or permission:

//Create FileInfo

FileInfo info = new FileInfo(path);

//Create FileSecurity

FileSecurity security = FileSystemAclExtensions.GetAccessControl(info);

//Create Privileges

SecurityIdentifier identifier = WindowsIdentity.GetCurrent().User;

//Set Owner

security.SetOwner(identifier);

//Set Access rules

security.AddAccessRule(new FileSystemAccessRule(identifier, FileSystemRights.FullControl, AccessControlType.Allow));

//Update Acces Controll on File

FileSystemAclExtensions.SetAccessControl(info, security);

My goal is to open a FileStream and Write over the File, here is a exaple:

File.SetAttributes(_recycleBin, FileAttributes.Normal);
string[] files = Directory.GetFiles(_recycleBin, "", System.IO.SearchOption.AllDirectories);

foreach (string file in files)
{
try
{
// Set the files attributes to normal in case it's read-only.

     File.SetAttributes(file, FileAttributes.Normal);

     // Calculate the total number of sectors in the file.
     double sectors = Math.Ceiling(new FileInfo(file).Length / 512.0);

     // Create a dummy-buffer the size of a sector.

     byte\[\] dummyBuffer = new byte\[512\];

     // Create a cryptographic Random Number Generator.
     // This is what I use to create the garbage data.

     RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();

     Trace.WriteLine("DEBUG LOG: " + file + "loaded.");

     FileStream inputStream = new FileStream(file, FileMode.Open);

     for (int currentPass = 0; currentPass < timesToWrite; currentPass++)
     {
         //UpdatePassInfo(currentPass + 1, timesToWrite);

         // Go to the beginning of the stream

         inputStream.Position = 0;

         // Loop all sectors
         for (int sectorsWritten = 0; sectorsWritten < sectors; sectorsWritten++)
         {
             //UpdateSectorInfo(sectorsWritten + 1, (int)sectors);

             // Fill the dummy-buffer with random data

             rng.GetBytes(dummyBuffer);

             // Write it to the stream
             inputStream.Write(dummyBuffer, 0, dummyBuffer.Length);
         }

         //Delete

But what is your question?

You're going to need to add a manifest to your project. Add -> Item -> Application Manifest File. Change the line that says requestedExecutionLevel from level="asInvoker" to level="requireAdministrator"
