備註

如果實體類型是透過參考導覽屬性所擁有,則會使用對應的外鍵屬性。

如果實體類型是透過集合導覽屬性所擁有,則會使用外鍵屬性設定複合主鍵,並具有符合上述命名慣例的額外屬性。

如需詳細資訊和範例,請參閱 模型建置慣例

建構函式

KeyDiscoveryConvention(ProviderConventionSetBuilderDependencies)

建立 KeyDiscoveryConvention 的新執行個體。

屬性

Dependencies

此服務的相依性。

方法

DiscoverKeyProperties(IConventionEntityType, IEnumerable<IConventionProperty>)

傳回應該用於主鍵的屬性。

ProcessEntityTypeAdded(IConventionEntityTypeBuilder, IConventionContext<IConventionEntityTypeBuilder>)

在實體類型新增至模型之後呼叫。

ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)

在實體類型的基底類型變更之後呼叫。

ProcessEntityTypeMemberIgnored(IConventionEntityTypeBuilder, String, IConventionContext<String>)

忽略實體類型成員之後呼叫。

ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)

在將外鍵新增至實體類型之後呼叫。

ProcessForeignKeyAdded(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)

在將外鍵新增至實體類型之後呼叫。

ProcessForeignKeyOwnershipChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)

在外鍵的擁有權值變更之後呼叫。

ProcessForeignKeyOwnershipChanged(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)

在外鍵的擁有權值變更之後呼叫。

ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)

在外鍵屬性或主體索引鍵變更之後呼叫。

ProcessForeignKeyPropertiesChanged(IConventionRelationshipBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IConventionRelationshipBuilder>)

在外鍵屬性或主體索引鍵變更之後呼叫。

ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)

移除外鍵之後呼叫。

ProcessForeignKeyUniquenessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)

在外鍵的唯一性變更之後呼叫。

ProcessForeignKeyUniquenessChanged(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)

在外鍵的唯一性變更之後呼叫。

ProcessKeyProperties(IList<IConventionProperty>, IConventionEntityType)

新增或移除要用於主鍵的屬性。

ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)

這是支援 Entity Framework Core 基礎結構的內部 API,不受與公用 API 相同的相容性標準。 它可能會在任何版本中變更或移除,而不會有任何通知。 您應該只在程式碼中直接使用它,並知道這麼做可能會導致應用程式在更新至新的 Entity Framework Core 版本時失敗。

ProcessPropertyAdded(IConventionPropertyBuilder, IConventionContext<IConventionPropertyBuilder>)

在屬性新增至實體類型之後呼叫。

ProcessPropertyFieldChanged(IConventionPropertyBuilder, FieldInfo, FieldInfo, IConventionContext<FieldInfo>)

在屬性的支援欄位變更之後呼叫。

ProcessSkipNavigationForeignKeyChanged(IConventionSkipNavigationBuilder, IConventionForeignKey, IConventionForeignKey, IConventionContext<IConventionForeignKey>)

在略過導覽反轉變更之後呼叫。

TryConfigurePrimaryKey(IConventionEntityTypeBuilder)

探索主鍵候選項目,並在找到時設定主鍵。
