操作顺序：

打开设备
卡认证
读卡

调用sdk的方法读卡等。

读卡

while (true)// { if (bgw.CancellationPending)// { e.Cancel = true; // return; } int authenticate = CVRSDK.CVR_Authenticate(); if (authenticate == 1) { int readContent = CVRSDK.CVR_Read_FPContent(); if (readContent != 1) { bgw.ReportProgress(100, '读卡失败'); Thread.Sleep(TimeSpan.FromSeconds(1));// continue; } } else { Thread.Sleep(TimeSpan.FromSeconds(1));// continue; } int length = 0; byte[] name = new byte[128]; length = 128; CVRSDK.GetPeopleName(ref name[0], ref length);//姓名 string nameStr = Encoding.GetEncoding('GB2312').GetString(name); // byte[] number = new byte[128]; length = 128; CVRSDK.GetPeopleIDCode(ref number[0], ref length);//身份证号码 string cardNoStr = Encoding.GetEncoding('GB2312').GetString(number); // string IsReadCardAddress = mesh.common.SystemSetting.GetSetting('IsReadCardAddress'); byte[] address = new byte[128]; length = 128; CVRSDK.GetPeopleAddress(ref address[0], ref length);//地址 string addressStr = Encoding.GetEncoding('GB2312').GetString(address); // bgw.ReportProgress(50, new object[] { nameStr, addressStr, cardNoStr }); Thread.Sleep(TimeSpan.FromSeconds(3)); // }
