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。

IConventionPropertyBuilder

如果套用組態，則為相同的產生器實例， null 否則為 。
