使用没有文件的服务帐户凭据初始化 firebase 管理 - System.NotSupportedException - "Tag '27' not supported."

Question

 public static  class ServiceAccountManager
 {
 public static ServiceAccountKey Datakey { get; private set; }

 public static void CreateKey(string serviceAccountEmail)
    {            
        Datakey = Service.Projects.ServiceAccounts.Keys.Create(
            new CreateServiceAccountKeyRequest(),
            "projects/-/serviceAccounts/" + serviceAccountEmail)
            .Execute();
        Console.WriteLine("Created key: " + Datakey.Name);
    }
 .......
 }

使用私钥初始化

   private static void InitializeFirebaseManagement()
    {
       
        var servicecredential = new ServiceAccountCredential(new 
   ServiceAccountCredential.Initializer(CloudManager.ProjectId)
            .FromPrivateKey("-----BEGIN PRIVATE KEY----- 
   "+ServiceAccountManager.Datakey.PrivateKeyData+"-----END PRIVATE KEY-----")
        );
        var credential =GoogleCredential.FromServiceAccountCredential(servicecredential);
   if (CloudManager.Credential.IsCreateScopedRequired)
        {
            credential =CloudManager.Credential.CreateScoped(FirebaseManagementService.Scope.CloudPlatform);
        _firebaseManagementService = new FirebaseManagementService(
           new BaseClientService.Initializer()
           {
               
               HttpClientInitializer = credential,
               ApplicationName = CloudManager.ApplicationName

           });         
        }
    }

Answer 1

Java代码：

InputStream stream = new ByteArrayInputStream(key.decodePrivateKeyData());
GoogleCredential credential = GoogleCredential.fromStream(stream);

C#:

var buffer = Convert.FromBase64String(ServiceAccountManager.DataKey.PrivateKeyData);
Stream stream = new MemoryStream(buffer);
GoogleCredential credential = GoogleCredential.FromStream(stream);
