查询Cassandra表单C#，未显示结果

问题描述

我正在尝试使用以下控制台在本地计算机上运行查询

I am trying to run the query form my local machine using console as below

select state from table limit 10 ALLOW FILTERING;

它给了我输出.

但是当我尝试使用控制台应用程序时，没有得到任何结果.
下面是代码

But when I am trying it form console application I am not getting any result.
Below is the code

  //Create a cluster instance using 3 cassandra nodes.
   var cluster = Cluster.Builder()
   .AddContactPoints("xx.xx.xx.xx")
   .Build();
    var session = cluster.Connect("keyspace");
    var rs = session.Execute("select state from table limit 10 ALLOW FILTERING");
    foreach (var row in rs)
    {
        var value = row.GetValue<string>("state");
    }

参考: https://docs.datastax.com/en/开发人员/csharp-driver/3.2/
我也没有收到任何错误.我正在使用"CassandraCSharpDriver"
