属性

名称	说明
Functions	提供在 LINQ to Entities 查询中使用时转换为数据库函数的 CLR 方法。在其他上下文（例如 LINQ to Objects）中调用这些方法将引发一个 NotSupportedException。
IsDesignTime	当从设计时工具（例如“dotnet ef”或其中一个程序包管理器控制台 PowerShell 命令“Add-Migration”、“Update-Database”等）运行代码时，此标志将设置为`true`此标志。

Constant<T>(T)	在 EF LINQ 查询的上下文中，强制将其参数作为常量表达式插入查询中。例如，出于查询性能原因，可以将值作为常量集成到 EF 查询中，而不是作为参数进行集成。
Parameter<T>(T)	在 EF LINQ 查询的上下文中，强制将其参数作为参数表达式插入查询中。这可用于确保将常量值参数化，而不是作为常量集成到查询中，这在动态查询构造方案中非常有用。
Property<TProperty>(Object, String)	引用实体或复杂类型实例上的给定属性或导航。这对于没有 CLR 属性的影子状态属性非常有用。目前，此方法只能在 LINQ 查询中使用，不能用于访问在其他方案中分配给属性的值。
