我正在尝试在SDK中提供的Credentialprovider的示例的基础上创建自己的Credential provider,实现用指纹登录windows 7系统，我查找了Windows Biometric Framework框架中的API，它只提供了WinBioSetCredential, WinBioGetCredentialStatus等相关的API，我的问题是刷指纹匹配成功后如何读取用WinBioSetCredential保存的Credential用于CSampleCredential::GetSerialization（xx）登录windows
7系统？以上只是我自己的思路，这条路行得通吗？还是说根本无法读取Credential?请各位朋友不吝赐教！ 另外，我安装过联想，DELL等的指纹管理软件，它们也是提供了自己的指纹登录模块的，所以我认为是可以实现的。
I'm trying to create my own Credentialprovider (based on the sample providered by SDK) to log on windows 7 via fingerprint, and I have learned the Windows Biometric Framework, only find api like WinBioSetCredential, WinBioGetCredentialStatus and so on. I'm
wondering whether i can read the credential saved by WinBioSetCredential and then sent it to CSampleCredential::GetSerialization（xx） to logon windows 7. i would appreciate it if you can give some suggestions.Thank you! (I installed the FMA of Lenovo and DELL
before and they providered their own fingerprint Credentialprovider, so I think it's possible to create my own fingerprint Credentialprovider.)
