HasNoRelationship(IReadOnlyList<IConventionProperty>, IConventionKey, IConventionEntityType, Boolean)

從這個實體類型中移除關聯性。
HasNoRelationship(IConventionForeignKey, Boolean)

從這個實體類型移除外鍵。

HasNoRelationship(IReadOnlyList<IConventionProperty>, IConventionKey, IConventionEntityType, Boolean)

從這個實體類型中移除關聯性。

public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder HasNoRelationship (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IConventionKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IConventionEntityType principalEntityType, bool fromDataAnnotation = false);
public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder? HasNoRelationship (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IConventionKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IConventionEntityType principalEntityType, bool fromDataAnnotation = false);
abstract member HasNoRelationship : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> * Microsoft.EntityFrameworkCore.Metadata.IConventionKey * Microsoft.EntityFrameworkCore.Metadata.IConventionEntityType * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder
Public Function HasNoRelationship (properties As IReadOnlyList(Of IConventionProperty), principalKey As IConventionKey, principalEntityType As IConventionEntityType, Optional fromDataAnnotation As Boolean = false) As IConventionEntityTypeBuilder

參數

properties
IReadOnlyList<IConventionProperty>

定義外鍵的屬性。

principalKey
IConventionKey

參考的主要或替代索引鍵。

principalEntityType
IConventionEntityType

關聯性針對的實體型別。 這可能與當關聯性以繼承階層中的衍生型別為目標時所定義的類型 principalKey 不同 (，因為索引鍵是在階層的基底類型上定義) 。

fromDataAnnotation
Boolean

指出是否已使用資料批註指定組態。

傳回

IConventionEntityTypeBuilder

如果已移除或不存在關聯性，則為相同的產生器實例， null 否則為 。

適用於

HasNoRelationship(IConventionForeignKey, Boolean)

從這個實體類型移除外鍵。

abstract member HasNoRelationship : Microsoft.EntityFrameworkCore.Metadata.IConventionForeignKey * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder
Public Function HasNoRelationship (foreignKey As IConventionForeignKey, Optional fromDataAnnotation As Boolean = false) As IConventionEntityTypeBuilder

參數

foreignKey
IConventionForeignKey

要移除的外鍵。

fromDataAnnotation
Boolean

指出是否已使用資料批註指定組態。
