c# - Nest.Search How do I get the field value for a short using Hits.Fields.FieldValue -

c# - Nest.Search<T> How do I get the field value for a short using Hits.Fields.FieldValue<object,short> -

i'm attempting homecoming required fields during utilize of search<t> returns isearchresponse<t>

i specifying fields bring e.g fields("abspath","urllen") , these indeed brought in responses' hits object.

note:page dto , contains public properties abspath (string) & urllen(short).

the documented method field contains string works fine:

var abspath = hits.fields.fieldvalue<page, string>(f => f.abspath)[0]

but trying short or int or long fails null exception (since urllen null):

var length= hits.fields.fieldvalue<page, short>(f => f.urllen)[0]

so missing here?

it fails because during look resolution (f=>f.urllen) resolve(...) method camel cases response fails.

sure plenty downloading source code github , adding in unit test confirms this. changing es object field name 'urllen' fixes problem. problem code area is

public string resolve(memberinfo info) { if (info == null) homecoming null; var name = info.name; **var resolvedname = name.tocamelcase();** var att = elasticattributes.property(info); if (att != null && !att.name.isnullorempty()) resolvedname = att.name; homecoming resolvedname; }

this design - see http://elasticsearch-users.115913.n3.nabble.com/lowercase-property-names-from-net-using-nest-td4039978.html quick fix. see http://nest.azurewebsites.net/nest/index-type-inference.html
