打开设备，获取句柄
循环读卡
判断设备是否断电
判断是否读到卡
判断是否读卡成功
获取姓名、身份证号码、地址信息
接口实现：
采用Windows api的接口方式，通过dllimport引入Windows api方法。
打开设备
private int Open()
{
int g_handle = 0;
try
{
g_handle = SS728M05Comom.ss_reader_open();
if (g_handle <= 0)
{
tsslMsg.Text = "连接设备失败！" + "," + DateTime.Now.TimeOfDay.ToString().Substring(0,8);
}
else
{
return g_handle;
}
}
catch (Exception ex)
{
tsslMsg.Text = "连接设备异常！" + "," + DateTime.Now.TimeOfDay.ToString().Substring(0,8);
return 0 ;
}
finally
{
}
return g_handle;
}
关闭设备
private void Close(int g_handle)
{
try
{
int iReturn = 0;
iReturn = SS728M05Comom.ss_reader_close(g_handle);
if (iReturn != 0)//关闭失败
{
tsslMsg.Text = "读卡器关闭失败" + "," + DateTime.Now.TimeOfDay.ToString().Substring(0,8);
return;
}
else//关闭成功
{
}
}
catch (Exception ex)
{
return;
}
finally
{
g_handle = 0;
}
}
