nest - How can I convert class properties into uppercase and rename few without Attribute in elasticsearch with c# -

i using elasticsearch in c# put data elasticsearch. have kept c# class & properties per database (pascalcase). however, requirement convert properties uppercase , change name of few name. same should possible class name well.

i not want achieve via data annotations. there way can made generic c# classes?

i using nest 5.x version.

for example,

class foo  {      public string thismessage {get; set; }      public string anothermessage {get; set; } } 

should convert into

class fooabc {     public string thismessage {get; set; }     public string {get; set; } } 

it's possible both nest without using attributes:

1. to change casing of poco property names when serialized , sent elasticsearch, use defaultfieldnameinferrer(func<string, string>)

2. to change name of type , rename properties, use infermappingfor<t>() typename() , rename()

here's example

void main() {     var pool = new singlenodeconnectionpool(new uri("http://localhost:9200"));     var defaultindex = "default-index";     var connectionsettings = new connectionsettings(pool)         .defaultfieldnameinferrer(s => s.toupperinvariant())         .infermappingfor<foo>(m => m             .typename("fooabc")             .rename(p => p.anothermessage, "another")         )         .defaultindex(defaultindex);      var client = new elasticclient(connectionsettings);      if (client.indexexists(defaultindex).exists)         client.deleteindex(defaultindex);      var indexresponse = client.index(new foo     {            thismessage = "this message",         anothermessage = "another message"     }); }  class foo {     public string thismessage { get; set; }     public string anothermessage { get; set; } } 

the index request , response

post http://localhost:9200/default-index/fooabc?pretty=true  {   "thismessage": "this message",   "another": "another message" }  status: 201 {   "_index" : "default-index",   "_type" : "fooabc",   "_id" : "avtahkdcii5clkx9kicz",   "_version" : 1,   "result" : "created",   "_shards" : {     "total" : 2,     "successful" : 1,     "failed" : 0   },   "created" : true }
