DbContextInfo 构造函数 (Type, ConnectionStringSettingsCollection)
[本页针对的是实体框架版本 6。最新版本以“实体框架”NuGet 包的形式提供。有关实体框架的更多信息，请参见 msdn.com/data/ef。]
注意：此 API 现在已过时。
通过使用指定上下文类型和连接字符串的设置来初始化 DbContextInfo 类。
命名空间： System.Data.Entity.Infrastructure
程序集： EntityFramework（在 EntityFramework.dll 中）
语法
声明
<ObsoleteAttribute("The application configuration can contain multiple settings that affect the connection used by a DbContext. To ensure all configuration is taken into account, use a DbContextInfo constructor that accepts System.Configuration.Configuration")> _
Public Sub New ( _
contextType As Type, _
connectionStringSettings As ConnectionStringSettingsCollection _
)
用法
Dim contextType As Type
Dim connectionStringSettings As ConnectionStringSettingsCollection
Dim instance As New DbContextInfo(contextType, _
connectionStringSettings)
[ObsoleteAttribute("The application configuration can contain multiple settings that affect the connection used by a DbContext. To ensure all configuration is taken into account, use a DbContextInfo constructor that accepts System.Configuration.Configuration")]
public DbContextInfo(
Type contextType,
ConnectionStringSettingsCollection connectionStringSettings
)
[ObsoleteAttribute(L"The application configuration can contain multiple settings that affect the connection used by a DbContext. To ensure all configuration is taken into account, use a DbContextInfo constructor that accepts System.Configuration.Configuration")]
public:
DbContextInfo(
Type^ contextType,
ConnectionStringSettingsCollection^ connectionStringSettings
)
[<ObsoleteAttribute("The application configuration can contain multiple settings that affect the connection used by a DbContext. To ensure all configuration is taken into account, use a DbContextInfo constructor that accepts System.Configuration.Configuration")>]
new :
contextType:Type *
connectionStringSettings:ConnectionStringSettingsCollection -> DbContextInfo
public function DbContextInfo(
contextType : Type,
connectionStringSettings : ConnectionStringSettingsCollection
)
参数
- contextType
类型：System.Type
派生自 DbContext 的类型。
- connectionStringSettings
类型：System.Configuration.ConnectionStringSettingsCollection
连接字符串的集合。
备注
更倾向使用接受整个配置文档的构造函数而非使用此构造函数。 提供整个配置文档将允许除了显式指定的连接字符串外，还可以在配置文档中找到 DefaultConnectionFactroy 项。
