一、卡密钥认证

private void button22_Click(object sender, EventArgs e) { byte passwordid; //密钥类型 byte[] uidbuf = new byte[8]; //卡UID byte[] authkeybuf = new byte[4]; //认证密钥 if (checkhexstr(textBox4.Text, 8, uidbuf, 0) == false) { MessageBox.Show("需要操作的卡片UID错误，可先执行寻卡操作获取UID！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } if (checkhexstr(textBox6.Text, 4, authkeybuf, 0) == false) { MessageBox.Show("卡片认证密钥输入错误，请输入8位16进制卡认证密钥！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); textBox6.Select(); return; } switch (comboBox2.SelectedIndex) { case 4: passwordid = 0x10; break; case 3: passwordid = 0x08; break; case 2: passwordid = 0x04; break; case 1: passwordid = 0x02; break; default: passwordid = 0x01; break; } byte ctrlword = 0x04; byte status = iso15693authkey(ctrlword, uidbuf, passwordid, authkeybuf); if (status == 0) { pcdbeep(50); MessageBox.Show("UID：" + textBox4.Text + " 密钥认证成功！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Information); } else { MessageErrInf(status); } }

二、更改卡密钥

private void button23_Click(object sender, EventArgs e) { byte passwordid; //密钥类型 byte[] uidbuf = new byte[8]; //卡UID byte[] newkeybuf = new byte[4]; //认证密钥 if (checkhexstr(textBox4.Text, 8, uidbuf, 0) == false) { MessageBox.Show("需要操作的卡片UID错误，可先执行寻卡操作获取UID！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } if (checkhexstr(textBox10.Text, 4, newkeybuf, 0) == false) { MessageBox.Show("卡片新密钥输入错误，请输入8位16进制卡新密钥！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); textBox10.Select(); return; } switch (comboBox2.SelectedIndex) { case 4: passwordid = 0x10; break; case 3: passwordid = 0x08; break; case 2: passwordid = 0x04; break; case 1: passwordid = 0x02; break; default: passwordid = 0x01; break; } byte ctrlword = 0x04; byte status = iso15693writekey(ctrlword, uidbuf, passwordid, newkeybuf); switch (status){ case 0: pcdbeep(50); MessageBox.Show("UID：" + textBox4.Text + " 更改卡密钥成功！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Information); break; case 47: MessageBox.Show("异常代码：47，上一条指令必须是认证密码指令......！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); break; default: MessageErrInf(status); break; } }

三、设置块密钥保护认证方式

private void button27_Click(object sender, EventArgs e) { byte[] uidbuf = new byte[8]; //卡UID if (checkhexstr(textBox4.Text, 8, uidbuf, 0) == false) { MessageBox.Show("需要操作的卡片UID错误，可先执行寻卡操作获取UID！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } byte blockpoint = (byte)HLblockpoint.Value; //高、低区分割块地址 byte extprotectstatus = (byte)(comboBox3.SelectedIndex + comboBox4.SelectedIndex * 16); //高、低区密钥保护模式 byte ctrlword = 0x04; byte status = iso15693protectblock(ctrlword, uidbuf, blockpoint, extprotectstatus); switch (status) { case 0: pcdbeep(50); MessageBox.Show("UID：" + textBox4.Text + " 块密码保护设定成功！" , "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); break; case 47: MessageBox.Show("异常代码：47，必须都认证读取密码和写入密码成功后再进行块密码保护设定！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); break; default: MessageErrInf(status); break; } }

四、读取卡内数据

private void button7_Click(object sender, EventArgs e) { //读卡块内数据 textBox5.Text = "22"; //操作多张卡标志用 byte ctrlword = System.Convert.ToByte(textBox5.Text, 16);//以十六进制方式转成数值 byte startblock = (byte)ctstartblock.Value; byte blocknum = (byte)ctblocknum.Value; byte[] uidbuf = new byte[8]; byte[] revbuf = new byte[255];//卡数据缓冲 byte[] revlen = new byte[1]; if (checkhexstr(textBox4.Text, 8, uidbuf, 0) == false) { MessageBox.Show("需要操作的卡片UID错误，可先执行寻卡操作获取UID！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } int j = 0; string carddatahex = ""; byte status = 8; while (j<blocknum) { status = iso15693readblock(ctrlword, System.Convert.ToByte(startblock + j), 1, uidbuf, revlen, revbuf); if (status == 0) { for (int i = 0; i < revlen[0]; i++) { carddatahex += revbuf[i].ToString("X02")+ " "; } j++; } else { j = blocknum; } } if (status==0) { richTextBox1.Text = carddatahex; pcdbeep(50); }else if (status==46 ){ MessageBox.Show("请先认证相应的密码！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); }else{ MessageErrInf(status);} }

五、写数据

private void button8_Click(object sender, EventArgs e) { //块写内数据 byte status;//存放返回值 byte ctrlword; byte startblock; byte blocknum; byte[] uidbuf = new byte[8]; byte[] writebuf = new byte[1024];//卡数据缓冲 byte[] mypiccdata = new byte[32]; byte eachblocksize; int revlen ; int i,j,p; //控制字指定,控制字的含义请查看本公司网站提供的动态库说明 switch (comboBox1.SelectedIndex) { case 2: eachblocksize = 32; break; case 1: eachblocksize = 8; break; default: eachblocksize = 4; break; } textBox5.Text = "22"; //操作多张卡标志用 ctrlword = System.Convert.ToByte(textBox5.Text, 16);//以十六进制方式转成数值 startblock =(byte)ctstartblock.Value ; blocknum =(byte)ctblocknum .Value ; revlen = Convert.ToInt16(blocknum * eachblocksize); if (checkhexstr(textBox4.Text, 8, uidbuf, 0) == false) { MessageBox.Show("需要操作的卡片UID错误，可先执行寻卡操作获取UID！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } if (checkhexstr(richTextBox1.Text, revlen, writebuf, 0) == false) { MessageBox.Show("需要写入的数据输入错误，可先执行读卡操作！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } j = 0; status = 8; while (j < blocknum) { for (p = 0; p < eachblocksize - 1; p++) {mypiccdata[p]=writebuf[j*eachblocksize+p]; } status = iso15693writeblock(ctrlword, System.Convert.ToByte(startblock + j), 1, uidbuf, eachblocksize, mypiccdata); if (status == 0) { j++; } else { j = blocknum; } } switch (status) { case 0: pcdbeep(50); MessageBox.Show("UID:" + textBox4.Text + "写卡成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); break; case 46: MessageBox.Show("请先认证相应的密码！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Stop); break; default: MessageErrInf(status); break; } }

六、修改SLIX1830标签UID

private void button21_Click(object sender, EventArgs e) { byte[] olduidbuf = new byte[8]; //旧uid缓冲 byte[] newuidbuf = new byte[8]; //新UID缓冲 //控制字指定,控制字的含义请查看本公司网站提供的动态库说明 byte ctrlword = 0; byte afi = System.Convert.ToByte(textBox1.Text, 16);//以十六进制方式转成数值 for (int i = 0; i < 8; i++) { olduidbuf[i] = 0; } if (checkhexstr(textBox4.Text, 8, newuidbuf, 0) == false) { MessageBox.Show("需要写入的卡片UID错误！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error); return; } byte status = iso15693writeuid(ctrlword, afi, olduidbuf, newuidbuf); if (status == 0) { pcdbeep(50); MessageBox.Show("UID：" + textBox4.Text + " 写入卡内成功！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Information); } else { MessageErrInf(status); } }
