HasIdentityColumnIncrement(IConventionPropertyBuilder, Nullable<Int32>, Boolean)	配置 SQL Server IDENTITY 的增量。
HasIdentityColumnIncrement(IConventionPropertyBuilder, Nullable<Int32>, StoreObjectIdentifier, Boolean)	为特定表配置SQL Server IDENTITY 的增量。

HasIdentityColumnIncrement(IConventionPropertyBuilder, Nullable<Int32>, Boolean)

配置 SQL Server IDENTITY 的增量。

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

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

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

<Extension()>
Public Function HasIdentityColumnIncrement (propertyBuilder As IConventionPropertyBuilder, increment 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。

increment: Nullable<Int32>

添加到加载的前一行的标识值的增量值。

fromDataAnnotation: Boolean

指示配置是否是使用数据注释指定的。

IConventionPropertyBuilder

如果应用了配置，则为同一生成器实例， null 否则为。
