else
byteLenght = Convert.ToInt32(fszie);
fszie = fszie - size;
byte[] data = new byte[byteLenght];
s.Read(data, 0, byteLenght);
streamWriter.Write(data, 0, byteLenght);
}
}
}
}
}

}

public static void UnZip(string FileToUpZip, string ZipedFolder)
{
UnZip(FileToUpZip, ZipedFolder, "");
}

#endregion

}

在 while ((theEntry = s.GetNextEntry()) != null)的地方 s.GetNextEntry()) 会抛出 Unexpected EOF 请问这个问题如何解决
