c# - How do i create a metadataId for a custom class derived from OrganizationRequest? -

i have created custom retrieve entity response class crm2011 serialize class. entity response class derived organizationrequest class. shown below:

public partial class retrieveentityrequest : organizationrequest {      public retrieveentityrequest()     {      }     private system.guid metadataidfield;     public system.guid metadataid     {                 {             return this.metadataidfield;         }         set         {             this.metadataidfield = value;         }     }      public entityfilters entityfilters { get; set; }     public string logicalname { get; set; }     public bool retrieveasifpublished { get; set; } } 

now when run code shown below

using (organizationserviceproxy serviceproxy = new organizationserviceproxy(organizationuri, homerealmuri, credentials, null)) {     try     {         serviceproxy.enableproxytypes();         request = new crmutilities.retrieveentityrequest();         request.logicalname=entityname;         request.entityfilters = entityfilters.entity;         request.requestname = requestname;          //execute request         retrieveentityresponse =   (crmutilities.retrieveentityresponse)serviceproxy.execute(request);     }      catch (system.web.services.protocols.soapexception ex)     {         throw ex;     }      catch (exception ex)     {         throw ex;     } } 

it says metadataid required field missing.the exception thrown organizationservicefault caught //required field 'metadataid' missing. how create metadataid custom object in case?

check out msdn documentation organizationrequest. 1 of properties parameters, collection of data needed request work.

your getter , setter should set (or retrieve) value collection. can't create private field , expect work. ;)

for record - other request classes available in crm sdk follow same pattern - derive organizationrequest , properties shortcuts manipulate required parameters.
