示例1: TarEntry

/// Construct an entry from an archive's header bytes. File is set
/// to null.
/// </summary>
/// <param name = "headerBuffer">
/// The header bytes from a tar archive entry.
/// </param>
public TarEntry(byte[] headerBuffer)

}示例2: GetNextEntry
/// <summary>
/// Get the next entry in this tar archive. This will skip
/// over any remaining data in the current entry, if there
/// is one, and place the input stream at the header of the
/// next entry, and read the header and instantiate a new
/// TarEntry from the header bytes and return that entry.
/// If there are no more entries in the archive, null will
/// be returned to indicate that the end of the archive has
/// been reached.
/// </summary>
/// <returns>
/// The next TarEntry in the archive, or null.
/// </returns>
