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
如果应用了配置,则为同一生成器实例, null
否则为 。
