If there is a relationship between Entity A and Entity B, such that there is a lookup for example in Entity B that has the value of a record in Entity A, you can do a simple QueryByAttribute or QueryExpression.

QueryByAttribute query = new QueryByAttribute();

query.ColumnSet = new ColumnSet(true);

query.EntityName = "new_entityb";

query.AddAttributeValue("new_entityaid", entityAId); // This is a Guid

RetrieveMultipleRequest request = new RetrieveMultipleRequest();

request.Query = query;

RetrieveMultipleResponse response = (RetrieveMultipleResponse)service.Execute(request);

Entity results = (Entity)response.EntityCollection.Entities[0];

try

{

Guid lookupId = new Guid();

lookupId = results.Id;

return lookupId;

}

catch (FaultException<OrganizationServiceFault> ex)

{

throw ex;

}

Hope this helps.

If these entities have a relationship, you can use a quick view form without writing any code technet.microsoft.com/.../dn531145.aspx

If you have relationship between these entities, you can use retrieve (as you will have lookup) otherwise you can use retrieve multiple to get record.

You can refer SDK : msdn.microsoft.com/.../gg328198.aspx

Thanks

Hi,

You could use QueryExpression in C# to retrieve the records of an entity in Dynamics CRM.

See: arunpotti.wordpress.com/.../retrieve-records-using-query-expression-c-sdk-in-crm/

Hope this helps.
