使用私钥将X509Certificate2导出到字节数组和导入到存储区

以下代码演示了如何导出带有私钥的证书：

X509Store store = new X509Store(StoreLocation.CurrentUser);

store.Open(OpenFlags.ReadOnly);

X509Certificate2 cert = store.Certificates[1];

// Export the certificate including the private key.
byte[] certBytes = cert.Export(X509ContentType.Pkcs12);

要保护导出的证书，请使用以下Export函数重载：

byte[] certBytes = cert.Export(X509ContentType.Pkcs12, "SecurePassword");

要导入证书，请使用以下代码：

X509Certificate2 certToImport = new X509Certificate2(arr, "SecurePassword");

// To mark it as exportable use the following constructor:
X509Certificate2 certToImport = new X509Certificate2(arr, "SecurePassword", X509KeyStorageFlags.Exportable);
// certToImport.HasPrivateKey must be true here!!

X509Store store2 = new X509Store(StoreName.TrustedPublisher,
                                 StoreLocation.CurrentUser);
store2.Open(OpenFlags.MaxAllowed);

store2.Add(certToImport);
store2.Close();
