问题描述
我正在尝试在 RavenDB 中检索文档，我在其中按 int 列表进行排序。
Queryable = Queryable.OrderBy(dto => SearchIds.IndexOf(dto.PropertyId));
上面的代码是我从这个 post 中找到的一个解决方案。
但是，当客户端需要将 LINQ 解析为 RQL 时，它会给我一个错误。
System.InvalidOperationException: Cannot understand how to translate value(infrastructure.DataAccess.HolidayHome.Filtering.PropertyInformationFilteringService).SearchIds.IndexOf(dto.PropertyId)

有没有更好的整数列表排序方式？
