HasValueGenerator(Func<IProperty,IEntityType,ValueGenerator>, Boolean)

ValueGenerator配置将为此属性生成值的 。

public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder HasValueGenerator (Func<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Metadata.IEntityType,Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> factory, bool fromDataAnnotation = false);
public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder? HasValueGenerator (Func<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Metadata.IEntityType,Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator>? factory, bool fromDataAnnotation = false);
abstract member HasValueGenerator : Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder
Public Function HasValueGenerator (factory As Func(Of IProperty, IEntityType, ValueGenerator), Optional fromDataAnnotation As Boolean = false) As IConventionPropertyBuilder

参数

factory
Func<IProperty,IEntityType,ValueGenerator>

将用于创建值生成器实例的委托。

fromDataAnnotation
Boolean

指示配置是否是使用数据注释指定的。

返回

IConventionPropertyBuilder

如果应用了配置，则为同一生成器实例， null 否则为 。
