定义

命名空间:

Microsoft.EntityFrameworkCore.Metadata

程序集:

Microsoft.EntityFrameworkCore.dll

包:

Microsoft.EntityFrameworkCore v8.0.0

重载

AddForeignKey(IMutableProperty, IMutableKey, IMutableEntityType)	向此实体类型添加新关系。
AddForeignKey(IReadOnlyList<IMutableProperty>, IMutableKey, IMutableEntityType)	向此实体类型添加新关系。

AddForeignKey(IMutableProperty, IMutableKey, IMutableEntityType)

向此实体类型添加新关系。

public virtual Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey AddForeignKey (Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.Metadata.IMutableKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType principalEntityType);

abstract member AddForeignKey : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey
override this.AddForeignKey : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey

Public Overridable Function AddForeignKey (property As IMutableProperty, principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

参数

property

IMutableProperty

定义外键时所基于的属性。

principalKey

IMutableKey

引用的主键或备用键。

principalEntityType

IMutableEntityType

作为关系目标的实体类型。 这可能不同于关系面向继承层次结构 (派生类型时定义的类型 principalKey ，因为键是在层次结构) 基类型上定义的。

返回

IMutableForeignKey

新建的外键。

AddForeignKey(IReadOnlyList<IMutableProperty>, IMutableKey, IMutableEntityType)

向此实体类型添加新关系。

public Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey AddForeignKey (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IMutableProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IMutableKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType principalEntityType);

abstract member AddForeignKey : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IMutableProperty> * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey

Public Function AddForeignKey (properties As IReadOnlyList(Of IMutableProperty), principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

参数

properties

IReadOnlyList<IMutableProperty>

定义外键的属性。

principalKey

IMutableKey

引用的主键或备用键。

principalEntityType

IMutableEntityType

作为关系目标的实体类型。 这可能不同于关系面向继承层次结构 (派生类型时定义的类型 principalKey ，因为键是在层次结构) 基类型上定义的。

返回

IMutableForeignKey

新建的外键。
