问如何在Elasticsearch 5中从.Net或NEST创建新索引

EN

using Nest;

namespace NEST5
{
  [ElasticsearchType(IdProperty = "data_id")]
  public class Test_Data
  {    
     public int data_id { get; set; }
     public string address { get; set; }
     public string location { get; set; }
  }
}

var connectionPool = new SingleNodeConnectionPool(new Uri("http://<ip here>:9200/"));
var settings = new ConnectionSettings(connectionPool, new InMemoryConnection())
 .DefaultIndex("test_data")
 .BasicAuthentication("username", "password");

var client = new ElasticLowLevelClient(settings);

var descriptor = new CreateIndexDescriptor("test_data")
 .Mappings(ms => ms
 .Map<Test_Data>(m => m.AutoMap())
 );

client.IndicesCreate<Test_Data>("test_data", descriptor, null);
