HasValueGenerator(Func<IProperty,IEntityType,ValueGenerator>, Boolean)
設定 ValueGenerator 將產生這個屬性值的 。
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
參數
- factory
- Func<IProperty,IEntityType,ValueGenerator>
將用來建立值產生器實例的委派。
- fromDataAnnotation
- Boolean
指出是否使用資料批註來指定組態。

如果套用組態,則為相同的產生器實例, null
否則為 。
