为 SQL Server IDENTITY 配置种子。

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder HasIdentityColumnSeed(this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder propertyBuilder, int? seed, bool fromDataAnnotation = false);

static member HasIdentityColumnSeed : Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder * Nullable<int> * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder

<Extension()>
Public Function HasIdentityColumnSeed (propertyBuilder As IConventionPropertyBuilder, seed As Nullable(Of Integer), Optional fromDataAnnotation As Boolean = false) As IConventionPropertyBuilder

参数

propertyBuilder: IConventionPropertyBuilder

要配置的属性的生成器。

seed: Nullable<Int32>

加载到表中的第一个行所使用的值。

fromDataAnnotation: Boolean

指示是否使用数据注释指定了配置。

IConventionPropertyBuilder

如果应用了配置，则为同一生成器实例， null 否则为同一个生成器实例。
