Hi, Is it possible to extract a file with the FileZip class even if the file already exist? atm i'm getting an error when extracting my zip file that the file does already exist.

C#

ZipFile.ExtractToDirectory(Application.StartupPath + @"\patch001.zip", Application.StartupPath);
File.Delete(Application.StartupPath + @"\patch001.zip");

If the library doesn't have an 'overwrite existing' flag, the easy thing to do, is check and delete it first.

Hi,

Try to do this:

C#

ZipArchive zipArchive = new ZipFile.OpenRead(Application.StartupPath + @"\patch001.zip");
foreach (ZipArchiveEntry entry in zipArchive.Entries)
{
      entry.ExtractToFile(Application.StartupPath + entry.Name, true);
}
zipArchive.Dispose();

Hope this helps.

Thanks, but when i'm doing it like that i'm getting this: "Error 1 foreach statement cannot operate on variables of type 'System.IO.Compression.ZipArchive' because 'System.IO.Compression.ZipArchive' does not contain a public definition for 'GetEnumerator'"
