在运行 net472 Web 应用程序的 Azure 应用程序服务中，我从密钥库访问证书，如下所示：

var certSecret = await kvClient.GetSecretAsync(kvName, secretName);

然后我需要发送证书以向外部服务进行身份验证

var cert = new X509Certificate2(Convert.FromBase64String(certSecret.Value));

此行会引发错误

System.Security.Cryptography.CryptographicException: The system cannot find the file specified.

尝试获取如下秘密：

var certSecret = await kvClient.GetSecretAsync(vaultBaseUrl, secretName);

您可以检索certSecret.value以检查它是否具有值，然后将其发送到X509Certificate2指定X509KeyStorageFlags存储标志的位置。

X509Certificate2 x509 = new X509Certificate2(Convert.FromBase64String(certSecret.value), string.Empty, X509KeyStorageFlags.MachineKeySet)
