asp.net mvc 5 - How to ignore properties marked with [IgnoreDataMember] when calling REST service -

i consuming rest xml service.

i have necessary classes this, (supplied dev wrote service) @ end have save of responses db perform tasks of app writing. have marked of these classes need put in db partial , extended them can inherit dbentity class specifies id property can use ef save them db thus:

public interface idbentity {     int id { get; set; } }  [serializable] public class dbentity : idbentity {     [ignoredatamember]     [xmlignore]     public int id { get; set; } } 

the problem facing now, when service call being de-serialized error

error in line 1 position 113. 'element' 'elementname' namespace '' not expected. expecting element '_x003c_id_x003e_k__backingfield'

i making call this:

var response = await client.postasxmlasync<treq>("some/api/call", req); tresp val = await msg.content.readasasync<tresp>(response) 

all properties in original classes have orders specified datamember attributes , have marked db properties ignored, no avail.

is there way can work? - ie getting datacontractserializer ignore properties have marked ignored when de-serializing?

as aside, these ignored properties being passed service when making call - ignoredatamember anything?

seems way this

public interface idbentity {     int id { get; set; } }  [serializable] [datacontract] public class dbentity : idbentity {     [xmlignore]     public int id { get; set; } } 

so adding datacontract attribute omitting datamember attribute on item don't want

don't know how missed first time around. seems opt in rather opt out in instance.
