我有 2 个表“内容”和“频道”。具有频道导航属性的内容
我在数据服务中创建了一个方法“GetContentsOfChannel”，该方法将channelID作为para并
通过执行下面的uri返回该channelID的所有内容我正在获取该频道id的所有内容
http://localhost:28553/WNADataService.svc/GetContentsOfChannel?channelID=37
但我也想要每个内容的频道详细信息，当我尝试使用 $expand 时，我收到错误
http://localhost:28553/WNADataService.svc/GetContentsOfChannel?channelID=37$expand=Channels
是我遗漏了一些东西还是有任何其他方式可以获取所有详细信息
请帮助我

它应该是
http://localhost:28553/WNADataService.svc/GetContentsOfChannel?channelID=37&$exp and=Channels&为了向查询字符串添加新参数
$expand - 用于加载相关实体的 OData 参数名称
it should be
http://localhost:28553/WNADataService.svc/GetContentsOfChannel?channelID=37&$expand=Channels& in order to add new param to query string
$expand - OData param name to load related entity
尝试使用 & 而不是 $
希望这会有所帮助。
Try using & insteadof $
Hope this helps.
