Function HasTranslation (translation As Func(Of IReadOnlyCollection(Of SqlExpression), SqlExpression), fromDataAnnotation As Boolean) As IConventionDbFunctionBuilder Implements IConventionDbFunctionBuilder.HasTranslation

參數

translation

Func<IReadOnlyCollection<SqlExpression>,SqlExpression>

要使用的翻譯。

fromDataAnnotation

Boolean

指出是否使用資料批註來指定組態。

傳回

IConventionDbFunctionBuilder

如果套用組態，則為相同的產生器實例， null 否則為 。

實作

HasTranslation(Func<IReadOnlyCollection<SqlExpression>,SqlExpression>, Boolean)
