c# - Automapper - RecognizePrefixes 不起作用

Question

我需要映射 PriorityId -> TcTaskPriorityId

 Mapper.Configuration.RecognizePrefixes("TcTask");
 Mapper.CreateMap<Task, TpTasksEntity>();

 Task t = new Task{PriorityId = 1};          
 var te = Mapper.Map<Task, TpTasksEntity>(t);

它就是行不通。

RecognizePrefixes 适用于源对象前缀，即:

Mapper.Configuration.RecognizePrefixes("TcTask");
Mapper.CreateMap<Task, TpTasksEntity>();

Task t = new Task { TcTaskPriorityId = 1 };
var te = Mapper.Map<Task, TpTasksEntity>(t);

对于您的场景，您可以编写自定义命名约定:

Mapper.Configuration.SourceMemberNameTransformer = s => "TcTask" + s;
Mapper.CreateMap<Task, TpTasksEntity>();

Task t = new Task { PriorityId = 1 };
var te = Mapper.Map<Task, TpTasksEntity>(t);
