Hi All,

I got error:

 Condition for attribute 'opportunity.opportunityid': expected argument(s) of type 'System.Guid' but received 'System.Object[]'.

I guest something wrong with my ConditionExpression Values = { opportunityfilter }.

Please advise. Thank you. My code as below:-

var opportunityfilter = crmOpportunities.ToArray()[0].Entities.Select(k => k.Attributes["opportunityid"]).Cast<Guid>().ToArray();   

//  Set up column set   
ColumnSet cols = new ColumnSet("opportunityid","...","...");   

ConditionExpression oppCondition = new Microsoft.Xrm.Sdk.Query.ConditionExpression

            {

                AttributeName ="opportunityid",

                Operator =ConditionOperator.In,

                Values = { opportunityfilter }

            };

FilterExpression filter = new FilterExpression();

            filter.FilterOperator =LogicalOperator.And;

            filter.AddCondition(oppCondition);

LinkEntity linkToOpportunity = new LinkEntity();

            linkToOpportunity.JoinOperator =JoinOperator.Inner;

            linkToOpportunity.LinkCriteria = filter;

            linkToOpportunity.LinkFromEntityName ="opportunityproduct";
            linkToOpportunity.LinkFromAttributeName ="opportunityid";

            linkToOpportunity.LinkToEntityName ="opportunity";

            linkToOpportunity.LinkToAttributeName ="opportunityid";

           

//  Create query 

QueryExpression query = new Microsoft.Xrm.Sdk.Query.QueryExpression()

            {

                EntityName ="opportunityproduct",               ColumnSet = cols,                Criteria = filter

            };

:

:

                   query.PageInfo.PagingCookie = (pageNumber == 1) ?null : multiResponse.EntityCollection.PagingCookie;

                    query.PageInfo.PageNumber = pageNumber++;

                    multiRequest =new RetrieveMultipleRequest();

                    multiRequest.Query = query;

                    multiResponse = (RetrieveMultipleResponse)crmService.Execute(multiRequest);  <<----Error
