实现

注解

对于使用 LINQ 生成器模式生成的查询，会返回完全 LINQ 表达式树；否则，返回包装此查询的常量表达式。For queries built by using LINQ builder patterns, this returns a full LINQ expression tree; otherwise, it returns a constant expression that wraps this query. 请注意，默认表达式不进行缓存。Note that the default expression is not cached. 这样，框架可以区分 LINQ 与 Entity SQL 查询。This allows the framework to differentiate between LINQ and Entity SQL queries.

此成员是显式接口成员的实现。This member is an explicit interface member implementation. 它只能在 ObjectQuery<T> 实例被强制转换为 IListSource 接口时使用。It can be used only when the ObjectQuery<T> instance is cast to an IListSource interface.
