C# IC卡验证密码总是返回4(未验证密码)
string key = "ffffffffffff"; byte [] b= Encoding.ASCII.GetBytes(key); st = rf_load_key(idev, 4, 5, b); MessageBox.Show("装载密码:" + st); st = rf_authentication(idev,4,5); MessageBox.Show("验证密码:" + st);有没有c#的demo 参考下 ，或者发到979891946@qq.com,谢谢了 --------------------编程问答-------------------- 找了C#的demo

--------------------编程问答-------------------- 您好！现在您这个只能读8位的id，怎么读14位或者说别的位数啊。
--------------------编程问答--------------------
那你把byte[] snr=new byte[16];这样的长度改大一点试试吧，这个问题我也不太清楚
补充：.NET技术 , C#
