。NEST中的弹性搜索

问题描述 投票:0回答:1

我正在尝试使用ASP.NET中的NEST获取ElasticSearch数据。使用按钮,单击该按钮后,我的数据将显示在文本框中。我是否需要将数据库放入项目中? ,当我单击该按钮时,不会显示任何数据。

我正在使用Visual Studio 2015,.NET Framework 4.6.1

我是初学者,因此我无法处理发生的错误。我将提供我的代码。

namespace ElasticsearchWeb{
public class shekspir
{
    public string type { get; set; }
    public int line_id { get; set; }
    public string play_name { get; set; }
    public int speech_number { get; set; }
    public float line_number { get; set; }
    public string speaker { get; set; }
    public string text_entry { get; set; }
}
public partial class Default : System.Web.UI.Page
{
    public static Uri GetElasticHost()
    {
        var host = "http://localhost:9200";
        return new Uri(host);
    }
    public static ElasticClient GetElasticClient(ConnectionSettings settings = null)
    {
        if (settings == null)
        {
            var node = GetElasticHost();
            var pool = new SingleNodeConnectionPool(node);
            settings = new ConnectionSettings(pool);
        }
        settings.DisableDirectStreaming(true);
        var client = new ElasticClient(settings);
        return client;
    }

    public static List<shekspir> GetAllShekspir(int ID)
    {
        var client = GetElasticClient();

        ISearchResponse<shekspir> result = null;

        result = client.Search<shekspir>(x => x
        .Index("shekspir")
        .Query(q => q
            .MatchAll())

        );

        List<shekspir> list = new List<shekspir>();
        foreach (var r in result.Hits)
        {
            shekspir a = r.Source;
            list.Add(a);
        }

        return list;
    }
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {

        List<shekspir> list = GetAllShekspir(1);

        foreach (shekspir u in list)
        {
            litInfo.Text += u.play_name + ": " + u.text_entry + "<br>";


        }

    }
}}

您的应用程序正在运行哪个版本的.Net运行时?您使用的弹性搜索Nest API版本期望使用.Net标准版本2.0,但找不到。]
