AutoMapper SourceMemberNameTransformer

Question

我想註冊一個屬性的自定義命名約定，我有許多域對象和相關的視圖模型。

該域對象有一個枚舉屬性PublishStatus和視圖模型有一個布爾值屬性Published。

如果我創建了一個像How do I get AutoMapper to deal with a custom naming convention?一樣的自定義SourceMemberNameTransformer，我只是返回原始字符串的屬性不匹配PublishStatus？

如果我正確理解你的問題，你可能想要一個ValueResolver。喜歡的東西：

public class PublishStatusResolver : ValueResolver<PublishStatus, bool> 
{ 
    protected override bool ResolveCore(PublishStatus status) 
    { 
     return status == PublishStatus.Published; 
    } 
} 

然後在映射代碼，你把它想：

.ForMember(dto => dto.Published, 
      opt => opt.ResolveUsing<PublishStatusResolver>() 
        .FromMember(src => src.PublishStatus))
