.net 如何将SignaturePropertyCriteria附加到ValueObject
我使用Sharp Architecture 1.6并遇到EntityDuplicateChecker的一个问题 我有一个实体,它有两个属性作为域签名,(int)CustomerId和一个表示一周(包括一年和一周数)的ValueObject 因此,在DB术语中,在CustomerId、Year和WeekNumber三列上有一个域签名 EntityDuplicateChecker仅支持对实体类型、值类型、字符串、日期和枚举的引用 是否有处理此场景的良好实践.net 如何将SignaturePropertyCriteria附加到ValueObject,.net,validation,s#arp-architecture,.net,Validation,S#arp Architecture,我使用Sharp Architecture 1.6并遇到EntityDuplicateChecker的一个问题 我有一个实体,它有两个属性作为域签名,(int)CustomerId和一个表示一周(包括一年和一周数)的ValueObject 因此,在DB术语中,在CustomerId、Year和WeekNumber三列上有一个域签名 EntityDuplicateChecker仅支持对实体类型、值类型、字符串、日期和枚举的引用 是否有处理此场景的良好实践 欢迎提出任何想法。您能将DomainSig
欢迎提出任何想法。您能将DomainSignature属性放在一个日期字段中,该字段存储该周的第一个星期一(例如,当Year=2010,WeekNumber=40时,则日期为2010-10-04)?然后,您需要Year和WeekNumber属性设置器中的逻辑来根据需要更改日期字段,以及date属性设置器中的逻辑来更改Year和WeekNumber字段
我最终做了自己的DuplicateEntityChecker,并将ComponentRegister改为使用它,而不是SharpArch one 我的班级看起来像这样
