Question

我需要映射PriorityId - ＆gt; TcTaskPriorityId

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

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

它不起作用。

Answer 1

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);

Answer 2

使用RecognizeDestinationPrefixes方法。

Answer 3

你可以尝试：

Mapper.Initialize(cfg => {
    cfg.RecognizePrefixes("TcTask");
    cfg.CreateMap<Task, TpTasksEntity>();
});

自动映射 - RecognizePrefixes不起作用
