x509证书IIS私钥访问[重复]

显然是因为每次重新生成密钥容器(或其他)时,我都是从一个文件打开它。以下是有效的代码:

X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
X509Certificate2 c = store.Certificates
    .Find(X509FindType.FindBySubjectName, SIGNED_SUBJECT, true) 
    .Cast<X509Certificate2>()
    .FirstOrDefault();
    store.Close();

RSACryptoServiceProvider rsa = c.PrivateKey as RSACryptoServiceProvider;
Console.WriteLine("Certificate thumbprint:" + c.Thumbprint);
Console.WriteLine("From machine key store?: " + rsa.CspKeyContainerInfo.MachineKeyStore);
Console.WriteLine("Key container name: " + rsa.CspKeyContainerInfo.KeyContainerName);
Console.WriteLine("Key unique container name: " + rsa.CspKeyContainerInfo.UniqueKeyContainerName);  

以前,当从我的原始文章(在这里我将证书作为文件打开)运行代码段时,每次打印到控制台的密钥信息都会更改。每次运行修改后的代码都会显示相同的信息。
