in our project using c# poco classes map fields in elasticsearch. use nest library. our project growing , continuously adding new properties , new data models, painful update c# poco classes in several places uptake new changes. have data in json format use data validation , other processing. looking forward use json data , index, update, search, etc without having provide c# poco classes. can point me how achieve this? appreciate help. let me know if more information needed.

this have today. (small example)

c# poco class:

public class testdatamodel {     public int id { get; set; }     public string value { get; set; }     public datetime? datetimefield { get; set; } }

}

elastic custom helper method:

      public async task<iindexresponse> indexasync<t>(t data, string indexname, string typename, long versionnumber) t : class     {         if (indexname == null)         {             throw new argumentnullexception("index name null. please provide index name insert data.");         }          return await client.indexasync(data, =>             .index(indexname)             .type(typename)             .version(versionnumber));     }

usage:

 iindexresponse response = await searchhelper.indexasync<testdatamodel>(data.toobject<testdatamodel>(), indexname, elastictype);
