My query returns account.name, account.account and account.parentaccountid.

I'm using Silverlight and CRM2011.

Now I'm having trouble to find out how to extract value from parentaccountid attribute.

I have silverlightextensionmethods.cs file included in my VS project, and I'm using GetAttributeValue<Guid>("parentaccountid") to get the value from parentaccountid.

The value returned is empty.

Has anyone any ideas how to accomplish this?

I can get any other attribute value, but parentaccountid in account and parentcustomerid in contact are making my life very difficult.

Code: FIRST I CREATE QUERYEXPRESSION:

---

string temp="name;accountid;parentaccountid";
string[] fields = temp.Split(';');
 QueryExpression query = new QueryExpression()
 {
           EntityName = entity,
          ColumnSet = new ColumnSet { Columns = new System.Collections.ObjectModel.ObservableCollection<string>(fields) },

         Criteria = new FilterExpression
          {
              FilterOperator = LogicalOperator.And,
             Conditions = 
             {
                   new ConditionExpression
                   {
                                AttributeName = parentidfield,
                                Operator = ConditionOperator.Equal,
                                Values = { id }
                   }
              }
           }
 };

 OrganizationRequest req = new OrganizationRequest();
 req.RequestName = "RetrieveMultiple";

 req["Query"] = query;

 service.BeginExecute(req, new AsyncCallback(GetChildren_ExecuteCallBack), service);

NEXT I TY TO READ VALUES FORM RESPONSE

void GetChildren_ExecuteCallBack(IAsyncResult childresult)
        {
            List<TreeRecord> listc = new List<TreeRecord>();
            try
            {
                OrganizationResponse childresponse = ((IOrganizationService)childresult.AsyncState).EndExecute(childresult);
                EntityCollection childresults = (EntityCollection)childresponse["EntityCollection"];

                if (childresults.Entities.Count > 0)
                {
                    TreeConfig sitm = new TreeConfig();
                    string sdisplay = "";

                    foreach (Entity childentity in childresults.Entities)
                    {
                        foreach (TreeConfig sitem in Configs)
                        {
                            if (sitem.EntityName == childentity.LogicalName)
                            {

                        sid =  "accountid";
                        pid = "parentaccountid";

                        int i = sdisplay.Split(';').Length;

                        for (int j = 0; j < i; j++)
                        {
                            try { sValue += childentity.GetAttributeValue<string>(fields[j]) + " "; }
                            catch (Exception ex)
                            {

                        childitem.Name = sValue;


                        childitem.EntityName = childentity.LogicalName;
                        childitem.Level = sitm.Level;

                        childitem.RecordId = childentity.GetEntityId&开发者_如何学JAVAlt;Guid>(sid);

                        try { childitem.ParentId = childentity.GetAttributeValue<Guid>(pid); }
                        catch

Instead of

childentity.GetAttributeValue<Guid>(pid)

use

childentity.GetAttributeValue<EntityReference>(pid)
