c# - MongoDB 可以从 mongo 客户端连接，但不能从 C# 驱动程序连接

Question

这件事现在会让我发疯。我试图让它工作 3 个小时，但没有任何结果。我安装了 mongodb 2.8rc4。我在 admin db 中创建了一个用户帐户。我可以使用 mongo localhost/agp -u dato0011 -p "MyPassword"连接到 mongod。我可以通过 db.auth 对其进行身份验证，但由于未知原因，这在 C# 驱动程序中不起作用。

连接字符串是 mongodb://dato0011:MyPWD@localhost/agp

我使用以下代码初始化数据库:

        var client = new MongoClient(ConfigurationManager.ConnectionStrings["Default"].ConnectionString);
        var server = client.GetServer();
        var db = server.GetDatabase("agp");

但是当我尝试保存时，出现异常:

Unable to connect to server 192.168.0.100:27017: Invalid credential for database 'agp'..

在内部异常的深处，有这条消息:

{ “认证”:1，“用户”:“dato0011”，“随机数”:“fc65b3c269560533”，“ key ”:“35589d31830b76c72358343bc054105f” }

还有这个

{"Command 'authenticate' failed: auth failed (response: { \"ok\" : 0.0, \"errmsg\" : \"auth failed\", \"code\" : 18 })"}

有人知道我做错了什么吗？ 谢谢。

更新

不知道是否有帮助，但这是抛出异常的代码:

Users.Save(user);

用户在哪里

Users = db.GetCollection<User>("users", WriteConcern.W1);

更新 2 显然，异常消息有点误导。驱动程序确实连接到 mongod，但由于未知原因无法进行身份验证。用户名和密码参数正确传递。这是 admin 数据库中的用户。

                                "db" : "agp"
                        },
                        {
                                "role" : "dbAdmin",
                                "db" : "agp"
                        }
                ]

在 MongoClientSettings 上使用 MongoCredentials -

    string username = "user";
    string password = "password";
    string mongoDbAuthMechanism = "SCRAM-SHA-1";
    MongoInternalIdentity internalIdentity = 
              new MongoInternalIdentity("admin", username);
    PasswordEvidence passwordEvidence = new PasswordEvidence(password);
    MongoCredential mongoCredential = 
         new MongoCredential(mongoDbAuthMechanism, 
                 internalIdentity, passwordEvidence);
    List<MongoCredential> credentials = 
               new List<MongoCredential>() {mongoCredential};


    MongoClientSettings settings = new MongoClientSettings();
    // comment this line below if your mongo doesn't run on secured mode
    settings.Credentials = credentials;
    String mongoHost = "127.0.0.1";
    MongoServerAddress address = new MongoServerAddress(mongoHost);
    settings.Server = address;

    MongoClient client = new MongoClient(settings);
