For example, if I have a contact lookup field, and each contact record has many attributes, such as id, name, company, etc. How do I get the value of, say, the company attribute? 例如，如果我有一个联系人查找字段，并且每个联系人记录都具有许多属性，例如id，姓名，公司等。我如何获得company属性的值？

Thanks in advance. 提前致谢。

Update: 更新：

I can now get the value id ({55FCBC5D-xxxx-xxxx-xxxx-005056A63DAF}) using Retrieve method provided by crm service, but i also need the text name of the value. 现在，我可以使用crm服务提供的Retrieve方法获取值id（{55FCBC5D-xxxx-xxxx-xxxx-005056A63DAF}），但我还需要该值的文本名称。 How can I do that? 我怎样才能做到这一点？

A contact lookup field is of type EntityReference . 联系人查找字段的类型为EntityReference 。 As such, it only contains the bare essentials needed to uniquely identify the record: its Id (in this case, "ContactId"), LogicalName (the name of the entity to which the reference belongs - in this case, "contact"), and, if you're lucky, Name (in this case, likely FullName ). 因此，它仅包含唯一标识记录所需的基本要素：其Id （在这种情况下为“ ContactId”）， LogicalName （引用所属的实体的名称-在这种情况下为“ contact”），并且，如果幸运的话，还可以使用Name （在这种情况下，可能是FullName ）。

So to get any additional information about the contact, you're going to have to ask the Contact entity for that information via a query using the EntityReference . 因此，要获取有关该联系人的任何其他信息，您将不得不通过使用EntityReference的查询向Contact实体询问该信息。 Id . Id There's lots of examples of this @StackOverflow and around the web - see CRM 2011: Getting entity with Javascript for a popular way here. @StackOverflow和网络上有很多示例，请参见CRM 2011：使用Java脚本获取实体，以了解一种流行的方式。

There is also a CodePlex project called " CRM 2011 Lookup Preview " that seems to cleverly preview this sort of information on forms, but this may/may not be what you're looking for. 还有一个名为“ CRM 2011查找预览 ”的CodePlex项目，该项目似乎可以巧妙地预览表单上的此类信息，但这可能不是您想要的。

通过使用两个查询解决了问题（crmService提供的Retrieve方法）。
