IConventionDiscriminatorBuilder.CanSetValue(Object, Boolean)

返回一个值，该值指示是否可以从此配置源设置鉴别器值。

bool IConventionDiscriminatorBuilder.CanSetValue (object value, bool fromDataAnnotation);
bool IConventionDiscriminatorBuilder.CanSetValue (object? value, bool fromDataAnnotation);
abstract member Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionDiscriminatorBuilder.CanSetValue : obj * bool -> bool
override this.Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionDiscriminatorBuilder.CanSetValue : obj * bool -> bool
Function CanSetValue (value As Object, fromDataAnnotation As Boolean) As Boolean Implements IConventionDiscriminatorBuilder.CanSetValue

参数

value
Object

鉴别器值。

fromDataAnnotation
