CRM4.0多个实体关联查询

C#代码实现如下

  LinkEntity link = new LinkEntity();
            link.LinkFromEntityName = "new_ddxy";
            link.LinkFromAttributeName = "new_salesorder";
            link.LinkToEntityName = "salesorder";
            link.LinkToAttributeName = "salesorderid";
            ConditionExpression cond = new ConditionExpression();
            cond.AttributeName = "ordernumber";
            cond.Operator = ConditionOperator.Equal;
            cond.Values = new string[] { "ORD-04412-708MJ0" };
            FilterExpression filter = new FilterExpression();
            filter.Conditions = new ConditionExpression[] { cond };
            filter.FilterOperator = LogicalOperator.And;
            link.JoinOperator = JoinOperator.Inner;
            link.LinkCriteria = filter;

            LinkEntity link2 = new LinkEntity();
            link2.LinkFromEntityName = "new_ddxy";
            link2.LinkFromAttributeName = "new_productpricelevel_kz";
            link2.LinkToEntityName = "new_productpricelevel_kz";
            link2.LinkToAttributeName = "new_productpricelevel_kzid";
            ConditionExpression cond2 = new ConditionExpression();
            cond2.AttributeName = "new_sftb";
            cond2.Operator = ConditionOperator.Equal;
            cond2.Values = new object[] { true };
            link2.JoinOperator = JoinOperator.Inner;

            FilterExpression filter2 = new FilterExpression();
            filter2.FilterOperator = LogicalOperator.And;
            filter2.Conditions = new ConditionExpression[] { cond2 };
            link2.LinkCriteria = filter2;

            QueryExpression query = new QueryExpression();
            query.EntityName = "new_ddxy";
            query.ColumnSet = new AllColumns();
            query.LinkEntities = new LinkEntity[] { link, link2 };
            BusinessEntityCollection entities = (BusinessEntityCollection)service.RetrieveMultiple(query);
