byte[] fdata = ByteFormat.FromHex("4321123");
Gen2TagFilter filter = new Gen2TagFilter(fdata.Length*8, fdata ,ModuleTech.Gen2.MemBank.TID, 0, false);
string accesspwdstr = "33332222";
uint passwd = uint.Parse(accesspwdstr, System.Globalization.NumberStyles.AllowHexSpecifier);
rdr.ParamSet("AccessPassword", passwd);
Gen2LockAct [] acts = new Gen2LockAct[3];
acts[0] = Gen2LockAct.EPC_LOCK;
acts[1] = Gen2LockAct.TID_UNLOCK;
acts[2] = Gen2LockAct.ACCESS_PERMALOCK;
Gen2LockAction lockact = new Gen2LockAction(acts);
rdr.LockTag(filter, lockact);
