以SQL Server為目標時，設定索引鍵屬性的值產生策略。

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder HasValueGenerationStrategy (this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder propertyBuilder, Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy? valueGenerationStrategy, bool fromDataAnnotation = false);

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder? HasValueGenerationStrategy (this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder propertyBuilder, Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy? valueGenerationStrategy, bool fromDataAnnotation = false);

static member HasValueGenerationStrategy : Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder * Nullable<Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy> * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder

<Extension()>
Public Function HasValueGenerationStrategy (propertyBuilder As IConventionPropertyBuilder, valueGenerationStrategy As Nullable(Of SqlServerValueGenerationStrategy), Optional fromDataAnnotation As Boolean = false) As IConventionPropertyBuilder

參數

propertyBuilder: IConventionPropertyBuilder

要設定之屬性的產生器。

valueGenerationStrategy: Nullable<SqlServerValueGenerationStrategy>

價值產生策略。

fromDataAnnotation: Boolean

指出是否已使用資料批註指定組態。

傳回

IConventionPropertyBuilder

如果已套用組態，則為相同的產生器實例， null 否則為。
