EF 类

定义

命名空间:

Microsoft.EntityFrameworkCore

程序集:

Microsoft.EntityFrameworkCore.dll

包:

Microsoft.EntityFrameworkCore v8.0.0

在应用程序代码中非常有用的静态方法，其中没有要从中访问方法的 EF 类型。 例如，在 LINQ 查询中引用阴影状态属性。

public static class EF

type EF = class

Public Class EF

继承

Object

EF

注解

请参阅 数据库函数 和使用 EF。EF Core 中的属性查询 以获取详细信息和示例。

属性

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。 在其他上下文中调用这些方法 (例如 LINQ to Objects) 将引发 NotSupportedException。
IsDesignTime	从设计时工具（例如“dotnet ef”或包管理器控制台 PowerShell 命令之一“Add-Migration”、“Update-Database”等）运行代码时，此标志设置为 true 。
