datastax的C# Driver for Apache Cassandra

原版的说明文档：http://www.datastax.com/documentation/developer/csharp-driver/1.0/webhelp/index.html#csharp-driver/quick_start/qsSimpleClientAddSession_t.html

先吐槽一下说明文档非人的简单

说明的简洁明快，一下子就明白怎么编写代码，但是有些地方确实不该太简洁的。给出的方法名和方法调用太不一致了，Session已经不是静态类了，但是文档里的例子还是静态类的写法。而在调用keyspace里的东西时必须连接上空间的，类似在命令端里的use keyspace，可是这个重要的过程变成了

_session = _cluster.Connect();

猿们痛恨写文档可以理解，不过如果文档过时了的话，建议还是改改的好。吐槽完毕，上一个完整过程的代码。

static void Main(string[] args)
        {
            Cluster cluster = Cluster.Builder().AddContactPoint("192.168.84.168").Build();
            Metadata metadata = cluster.Metadata;
            var list=metadata.GetKeyspaces();
            for (int i = 0; i < list.Count; i++)
            {
                Console.WriteLine("spacename: " + list.ElementAt(i));
            }
            Session session = cluster.Connect();//Session的方法不是静态的
             string keyspace="t1";
             session.CreateKeyspace(keyspace);//创建空间
             session.ChangeKeyspace(keyspace);//连接到空间，文档里少这个
             session.Execute("CREATE TABLE " + keyspace + "." + keyspace + "t (id uuid PRIMARY KEY,title text);");
             PreparedStatement statement = session.Prepare("INSERT INTO " + keyspace + "." + keyspace + "t (id, title) VALUES (?, ?);");
             BoundStatement boundStatement = new BoundStatement(statement);
             session.Execute(boundStatement.Bind(new Guid("756716f7-2e54-4715-9f00-91dcbea6cf50"),"La Petite Tonkinoise"));
            var tablelist= metadata.GetTables(keyspace);
            for (int i = 0; i < tablelist.Count; i++)
            {
                Console.WriteLine("table: " + tablelist.ElementAt(i));
            }
            RowSet results = session.Execute("SELECT * FROM " + keyspace + "." + keyspace + "t WHERE id = 756716f7-2e54-4715-9f00-91dcbea6cf50;");
            Console.WriteLine("-------------------------------+-----------------------+--------------------");
            foreach (Row row in results.GetRows())
            {
                Console.WriteLine(String.Format("{0, -40}	{1, -20}	",row.GetValue<Guid>("id").ToString(), row.GetValue<String>("title")));
            }
            cluster.Shutdown();
            Console.Read();
        }
