使用卡桑德拉。 NET以编程方式访问 Amazon Keyspaces 的核心客户端驱动程序

下载 Starfield 证书并将其保存到本地目录，同时记下路径。以下是使用的示例 PowerShell。

$client = new-object System.Net.WebClient
$client.DownloadFile("https://certs.secureserver.net/repository/sf-class2-root.crt","path_to_file\sf-class2-root.crt")

使用 nuget assandraCSharp 控制台通过 nuget 安装 C 驱动程序。

PM> Install-Package CassandraCSharpDriver

以下示例使用。 NET用于连接到 Amazon Keyspaces 并运行查询的核心 C# 控制台项目。

using Cassandra;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Security;
using System.Runtime.ConstrainedExecution;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Threading.Tasks;

namespace CSharpKeyspacesExample
{
    class Program
    {
        public Program(){}

        static void Main(string[] args)
        {
            X509Certificate2Collection certCollection = new X509Certificate2Collection();
            X509Certificate2 amazoncert = new X509Certificate2(@"path_to_file\sf-class2-root.crt");
            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);
            }
        }
    }
}
