如果返回的记录数低于 5000，这会失败吗？

Question

我有一个针对我编写的 QueryExpression 的多请求。在某些情况下，会返回超过 5000 条记录，而在其他情况下，会返回不到 5000 条记录。我担心如果计数小于 5000，这会失败。这是真的吗？！

 QueryExpression queryService = conversionResponse.Query;
                int pageNumber = 1;
                RetrieveMultipleRequest multiRequest;
                RetrieveMultipleResponse multiResponse = new RetrieveMultipleResponse();

                do
                {
                    queryService.PageInfo.Count = 5000;
                    queryService.PageInfo.PagingCookie = (pageNumber == 1) ? null : multiResponse.EntityCollection.PagingCookie;
                    queryService.PageInfo.PageNumber = pageNumber++;

                    multiRequest = new RetrieveMultipleRequest
                    {
                        Query = queryService
                    };
                    multiResponse = (RetrieveMultipleResponse)service.Execute(multiRequest);

                    Allergies.Entities.AddRange(multiResponse.EntityCollection.Entities);
                } while (multiResponse.EntityCollection.MoreRecords);

两种情况都应该没问题。

这里有一个类似的 MSDN 示例； Sample: Use QueryExpression with a paging cookie.
