假设您正在寻找一种方法来获取特定记录的所有关联记录。如果是这样的话,我会写这样的东西。希望有帮助。private EntityCollection GetAssociatedRecords(string relationshipName, string relatedEntityName, string entityName, Guid entityId,OrganizationService service) { EntityCollection result = null; try { QueryExpression query = new QueryExpression(); query.EntityName = relatedEntityName; query.ColumnSet = new ColumnSet(false); Relationship relationship = new Relationship(); relationship.SchemaName = relationshipName; relationship.PrimaryEntityRole = EntityRole.Referencing; RelationshipQueryCollection relatedEntity = new RelationshipQueryCollection(); relatedEntity.Add(relationship, query); RetrieveRequest request = new RetrieveRequest(); request.RelatedEntitiesQuery = relatedEntity; request.ColumnSet = new ColumnSet(true); request.Target = new EntityReference { Id = entityId, LogicalName = entityName }; RetrieveResponse response = (RetrieveResponse)service.Execute(request); RelatedEntityCollection relatedEntityCollection = response.Entity.RelatedEntities; if (relatedEntityCollection.Count > 0) { if (relatedEntityCollection.Values.Count > 0) { result = (EntityCollection)relatedEntityCollection.Values.ElementAt(0); } } } catch (Exception exception) { throw exception; } return result; }根据其他实体的角色,在引用和引用之间更改主要实体角色。希望有帮助。让我知道我的假设是否错误。
