关于X509证书

[kkk3k3k]

代码如下：在我的机器上WIn7 32位旗舰版 一起运行正常 可以获取证书信息，在XP的机器上也运行正确

但是在客户的机器上 WIn7 64位旗舰版, StoreName.My和AddressBook都没有得到证书信息，也没有发生异常

现在想知道原因？ 是缺少权限还是其他什么原因？ 非常感谢 不吝赐教。

你的代码没有错误，在WIN8.1 X64添加下编译运行正常。 请确认客户电脑上面安装过证书。

谢谢 我在看看

我的个天啊，难道是ms的bug? 以下转自: http://stackoverflow.com/questions/4471715/x509certificatestore-findcertificatebysubjectname-does-not-work-in-x64 It looks like there's a bug in the Find methods of this class which prevents them from working in x64. Specifically they're using IntPtrs to send data to native methods. As a work around you can loop through the certificates in the store and do your comparison manually (see sample below), though even in the hack it would be better to use the thumbprint or serial number. A better solution is to re-plumb your application to use the supported class System.Security.Cryptography.X509Certificates.X509Store to access your certificates. This class does work in 64 bit mode.

foreach(X509Certificate cert in store.Certificates)
{
    if (cert != null && cert.Subject.Contains("CN=my cert bla bla"))
        return cert;
}
Console.WriteLine("Not found!");

好像你用了上面讨论中的方法，也不行。

试试把项目改成x86试一试。
