传输智能卡数据时出错 [英] Error Transmiting smart card data
问题描述
我是智能阅读器技术的新手.我正在开发一个简单的应用程序，以使用.NET和c#从智能卡读取数据.电话是带有生物识别附件的MC75A，而sdk是BSCR sdk 2.2版.我正在使用sdk提供的WinSCard，后者是winscard.dll的包装.
在下面发布的代码中，我正在连接至卡并尝试从智能卡获取ID.我得到了apdu命令，可从Cardman_5x21-CL_Reader_Developers_Guide的card中检索UID.提到此功能适用于所有符合ISO 14443 A/B或ISO 15693的卡.我正在使用的卡可以进行PIV互操作.我已经尝试过各种方法，但是我一直停留在WinSCard.Transmit命令的位置，并给出错误代码:80100069.我无法弄清楚.有人请指导我我做错了什么吗?该代码粘贴在下面.提前谢谢.
I am new to smart reader tech. I am developing a simple application to read data from smart card using .NET and c#. The phone is MC75A with biometric attachment and sdk is BSCR sdk version 2.2. I am using the WinSCard provided by the sdk which is a wrapper for winscard.dll.
In the code posted below, I am connecting to the card and trying to get the id from the smart card. I got the apdu command to retrieve UID from card from the Cardman_5x21-CL_Reader_Developers_Guide. It is mentioned that this works with every ISO 14443 A/B or ISO 15693 compliant card. The card I am using is PIV-Interoperable. I have tried various things but I am stuck at the point where it goes to WinSCard.Transmit command and gives error code: 80100069. I am not able to figure it out. Anyone please direct me what I am doing wrong? The code is pasted below. Thanks in advance.

推荐答案
您看过这里吗? http://www.codeguru.com/forum/showthread.php?t=450642(尽管在VB中.)
他们讨论了SCARD_W_REMOVED_CARD错误，以及由于调用函数所使用的值类型不正确而可能导致的错误.
Have you looked here? http://www.codeguru.com/forum/showthread.php?t=450642 (Though it''s in VB. )
They talk about the SCARD_W_REMOVED_CARD error and how it might be because of the value types used in calling the functions are not correct.
