C# - Servicestack MongoDB JSON Objects Unescape -

i have got 2 problems.

i have local mongodb several collections.

a database object looks this:

my configuration looks this:

​using funq; using servicestack; using servicestack.text; namespace protocol.server.api {     public class apihost : appselfhostbase     {         public apihost() : base("api rest service", typeof(apihost).assembly)         {         }         public override void configure(container container)         {             plugins.add(new corsfeature());             setconfig(new hostconfig             {                 defaultcontenttype = mimetypes.json,                     enablefeatures = feature.all.remove(feature.html)             });             jsconfig.convertobjecttypesintostringdictionary = true;          }     } } 

my request definition this: public async task get(getobjects request) { var collection = connect.database.getcollection("cylinders"); var aggregate = collection.find( => true); var results = await aggregate.tolistasync(); return results; }

using servicestack; namespace protocol.server.api.clients {     [route("/objects")]     public class getobjects : ireturn<string>     {     } }  using mongodb.bson; using mongodb.driver; using mongodbtest; using servicestack; using system; using system.threading.tasks; namespace protocol.server.api.clients {     public class clientservice : servicestack.service     {         public async task<object> get(getobjects request)         {             var collection = connect._database.getcollection<bsondocument>("cylinders");             var aggregate = collection.find(_ => true);             var results = await aggregate.tolistasync();              return results;         }      } } 

problem 1: json objects not escaped , quite strange (backslahes , on).

problem 2 (aggregation): want aggregate objects in specific format.

i wrote this:

var collection = connect._database.getcollection<bsondocument>("cylinders");            var aggregate = collection.aggregate().group(new bsondocument {                { "_id", "$_id" },            });           var results = await aggregate.tolistasync(); 

this works perfectly, if want aggregate more fields, not work:

var aggregate = collection.aggregate().group(new bsondocument {                { "_id", "$_id" },                { "availableat", "$description.availableat" }            });​ 

how solve problems?

it's not recommended return json string in servicestack service prohibits being able access response in other format , prevents many other of servicestack's surrounding metadata features around services.

your services should returning clean poco's can serialized in registered format, returning bsondocument poor response serialize , explains why you're getting escaped json you're serializing object contains json in string instead of clean dto.

so should change services return clean poco's like:

public async task<list<cylinder>> get(getobjects request) {     var collection = connect._database.getcollection<cylinder>();     var aggregate = collection.find(_ => true);     var results = await aggregate.tolistasync();     return results; }
