ConventionPropertyExtensions.SetValueGeneratorFactory 方法

定义

设置工厂以用于为此属性生成值,或 null 清除以前设置的任何工厂。

设置 null 不会禁用此属性的值生成,它只会清除为此属性显式配置的任何生成器。 数据库提供程序可能仍具有属性类型的值生成器。

public static void SetValueGeneratorFactory (this Microsoft.EntityFrameworkCore.Metadata.IConventionProperty property, Func<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Metadata.IEntityType,Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> valueGeneratorFactory, bool fromDataAnnotation = false);
public static Func<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Metadata.IEntityType,Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> SetValueGeneratorFactory (this Microsoft.EntityFrameworkCore.Metadata.IConventionProperty property, Func<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Metadata.IEntityType,Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> valueGeneratorFactory, bool fromDataAnnotation = false);
static member SetValueGeneratorFactory : Microsoft.EntityFrameworkCore.Metadata.IConventionProperty * Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> * bool -> unit
static member SetValueGeneratorFactory : Microsoft.EntityFrameworkCore.Metadata.IConventionProperty * Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> * bool -> Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator>
<Extension()>
Public Sub SetValueGeneratorFactory (property As IConventionProperty, valueGeneratorFactory As Func(Of IProperty, IEntityType, ValueGenerator), Optional fromDataAnnotation As Boolean = false)
<Extension()>
Public Function SetValueGeneratorFactory (property As IConventionProperty, valueGeneratorFactory As Func(Of IProperty, IEntityType, ValueGenerator), Optional fromDataAnnotation As Boolean = false) As Func(Of IProperty, IEntityType, ValueGenerator)

参数

property
IConventionProperty

要为其设置值生成器的属性。

valueGeneratorFactory
Func<IProperty,IEntityType,ValueGenerator>

将用于创建值生成器或 null 清除任何以前设置的工厂的工厂。

fromDataAnnotation
Boolean

指示配置是否是使用数据注释指定的。

返回

配置的值。
