CanSetValueGenerationStrategy(IConventionPropertyBuilder, Nullable<SqlServerValueGenerationStrategy>, Boolean)	返回一个值，该值指示是否可以将给定值设置为值生成策略。
CanSetValueGenerationStrategy(IConventionPropertyBuilder, Nullable<SqlServerValueGenerationStrategy>, StoreObjectIdentifier, Boolean)	返回一个值，该值指示是否可以将给定值设置为特定表的值生成策略。

CanSetValueGenerationStrategy(IConventionPropertyBuilder, Nullable<SqlServerValueGenerationStrategy>, Boolean)

返回一个值，该值指示是否可以将给定值设置为值生成策略。

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

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

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

参数

propertyBuilder

IConventionPropertyBuilder

要配置的属性的生成器。

valueGenerationStrategy

Nullable<SqlServerValueGenerationStrategy>

价值生成策略。

fromDataAnnotation

Boolean

指示配置是否是使用数据注释指定的。

返回

Boolean

true 如果给定值可以设置为默认值生成策略，则为 。
