C# bir dosya halletmek: ile Hatası 'Thumbs.db'

Question

Ben SharpZipLib kullanarak bir dosyayı (.zip) halletmek bir program ...

Aşağıdaki kod yazdım:

public void UnZip(string zipFilePath, string extractionPath) 
{ 
    FastZip fz = new FastZip(); 
    fz.ExtractZip(zipFilePath, extractionPath, null); 
} 

alıyorum aşağıdaki İstisna:
ek bilgiler: yolundan "C:\Program files (x86)\... Thumbs.db" erişim reddedildi.
Program, Admin hakları ile başlar ve .zip arşivinde "Thumbs.db" dosyası yoktur.

Daha fazla kimbilir?
Greets ve teşekkür!

"Thumbs.db" dosyasını bir OS dosyası olarak görmezden gelirim.

Belki böyle bir şey:

using ICSharpCode.SharpZipLib.Core; 
using ICSharpCode.SharpZipLib.Zip; 

public void ExtractZipFile(string archiveFilenameIn, string password, string outFolder) { 
    ZipFile zf = null; 
    try { 
     FileStream fs = File.OpenRead(archiveFilenameIn); 
     zf = new ZipFile(fs); 
     if (!String.IsNullOrEmpty(password)) { 
      zf.Password = password;  // AES encrypted entries are handled automatically 
     } 
     foreach (ZipEntry zipEntry in zf) { 
      if (!zipEntry.IsFile) { 
       continue;   // Ignore directories 
      } 
      String entryFileName = zipEntry.Name; 
      // to remove the folder from the entry:- entryFileName = Path.GetFileName(entryFileName); 
      // Optionally match entrynames against a selection list here to skip as desired. 
      // The unpacked length is available in the zipEntry.Size property. 

      byte[] buffer = new byte[4096];  // 4K is optimum 
      Stream zipStream = zf.GetInputStream(zipEntry); 

      // Manipulate the output filename here as desired. 
      String fullZipToPath = Path.Combine(outFolder, entryFileName); 
      string directoryName = Path.GetDirectoryName(fullZipToPath); 
      if (directoryName.Length > 0) 
       Directory.CreateDirectory(directoryName); 

      // Unzip file in buffered chunks. This is just as fast as unpacking to a buffer the full size 
      // of the file, but does not waste memory. 
      // The "using" will close the stream even if an exception occurs. 
      using (FileStream streamWriter = File.Create(fullZipToPath)) { 
       StreamUtils.Copy(zipStream, streamWriter, buffer); 
      } 
     } 
    } finally { 
     if (zf != null) { 
      zf.IsStreamOwner = true; // Makes close also shut the underlying stream 
      zf.Close(); // Ensure we release resources 
     } 
    } 
}
