C# 控制台应用程序尝试连接到 AWS Cassandra 服务？

Question

我使用 C# cassandra 驱动程序尝试通过控制台应用程序连接到 AWS Cassandra 服务。 (c# cassandra 驱动程序：https://github.com/datastax/csharp-driver) 我还下载了 AmazonRootCA1.pem 并将其导入到根文件夹中

但是每次我尝试连接它都会因为 SSL 失败：

Cluster cluster = Cluster.Builder()
                .AddContactPoint("cassandra.us-east-2.amazonaws.com")
                .WithPort(9142)
                .WithAuthProvider(new PlainTextAuthProvider("LoginName", "Password"))
                .WithSSL()
                .Build();

            var session = cluster.Connect("tutorialkeyspace");

            var rs = session.Execute("SELECT * FROM tutorialtable");

            foreach (var row in rs)
            {
                var value = row.GetValue<int>("sample_int_column");
                Console.WriteLine("Success");
            }

有人可以帮助我我做错了什么吗？

非常感谢。

试试下面的 C# 示例

X509Certificate2Collection certCollection = new X509Certificate2Collection();
            X509Certificate2 amazoncert = new X509Certificate2(@"path_to_file\AmazonRootCA1.pem");
            var userName = "ServiceUserName";
            var pwd = "ServicePassword";
            certCollection.Add(amazoncert);
 
            var awsEndpoint =  "cassandra.us-east-2.amazonaws.com" ;  

            var cluster = Cluster.Builder()
                     .AddContactPoints(awsEndpoint)
                     .WithPort(9142)
                     .WithAuthProvider(new PlainTextAuthProvider(userName, pwd))
                     .WithSSL(new SSLOptions().SetCertificateCollection(certCollection))
                     .Build();

            var session = cluster.Connect();
            var rs = session.Execute("SELECT * FROM system_schema.tables;");
            foreach (var row in rs)
            {
                var name = row.GetValue<String>("keyspace_name");
                Console.WriteLine(name);
            }
        }
