RelationshipManager.InitializeRelatedReference<TTargetEntity> 方法

定义

命名空间:
System.Data.Objects.DataClasses
程序集:
System.Data.Entity.dll

使用无参数构造函数初始化已创建的现有 EntityReference<TEntity> 函数。

public:
generic <typename TTargetEntity>
 where TTargetEntity : class, System::Data::Objects::DataClasses::IEntityWithRelationships void InitializeRelatedReference(System::String ^ relationshipName, System::String ^ targetRoleName, System::Data::Objects::DataClasses::EntityReference<TTargetEntity> ^ entityReference);
public:
generic <typename TTargetEntity>
 where TTargetEntity : class void InitializeRelatedReference(System::String ^ relationshipName, System::String ^ targetRoleName, System::Data::Objects::DataClasses::EntityReference<TTargetEntity> ^ entityReference);
[System.ComponentModel.Browsable(false)]
public void InitializeRelatedReference<TTargetEntity>(string relationshipName, string targetRoleName, System.Data.Objects.DataClasses.EntityReference<TTargetEntity> entityReference) where TTargetEntity : class, System.Data.Objects.DataClasses.IEntityWithRelationships;
[System.ComponentModel.Browsable(false)]
public void InitializeRelatedReference<TTargetEntity>(string relationshipName, string targetRoleName, System.Data.Objects.DataClasses.EntityReference<TTargetEntity> entityReference) where TTargetEntity : class;
[<System.ComponentModel.Browsable(false)>]
member this.InitializeRelatedReference : string * string * System.Data.Objects.DataClasses.EntityReference<'argetEntity (requires 'argetEntity : null and 'argetEntity :> System.Data.Objects.DataClasses.IEntityWithRelationships)> -> unit (requires 'argetEntity : null and 'argetEntity :> System.Data.Objects.DataClasses.IEntityWithRelationships)
[<System.ComponentModel.Browsable(false)>]
member this.InitializeRelatedReference : string * string * System.Data.Objects.DataClasses.EntityReference<'argetEntity (requires 'argetEntity : null)> -> unit (requires 'argetEntity : null)
Public Sub InitializeRelatedReference(Of TTargetEntity As {Class, IEntityWithRelationships}) (relationshipName As String, targetRoleName As String, entityReference As EntityReference(Of TTargetEntity))
Public Sub InitializeRelatedReference(Of TTargetEntity As Class) (relationshipName As String, targetRoleName As String, entityReference As EntityReference(Of TTargetEntity))

类型参数

TTargetEntity

要初始化的类型 EntityReference<TEntity> 。

参数

relationshipName
String

关系名称。

targetRoleName
String

相关端的角色名称。

entityReference
EntityReference<TTargetEntity>

要 EntityReference<TEntity> 初始化的。

属性
BrowsableAttribute

例外

InvalidOperationException

当已初始化所提供的 EntityReference<TEntity> 内容时。

-或-

当关系管理器已附加到 .ObjectContext

-或-

当关系管理器已包含具有此名称和目标角色的关系时。

注解

该方法 InitializeRelatedReference 初始化使用无参数构造函数创建的现有 EntityReference<TEntity> 函数。 EntityReference<TEntity>使用提供的关系和目标角色名称初始化该角色。

该方法 InitializeRelatedReference 仅在反序列化期间使用。
