英文:
Mapster not mapping derived class in a List c#
问题
I have multiple classes implementing a base class, e.g.:
public abstract class Step
{
public StepId Id {get; set;}
public string Text {get; set;
public StepType Type {get;set;}
}
public class SelectionStep : Step
{
public List<string> Selections {get; set;}
}
public class NumericStep : Step
{
}
With the following Mapster configs:
config.NewConfig<SelectionStep, StepResponse>()
.Map(dest => dest.Selections, src => src.Selections.Select(x => x.Value));
config.NewConfig<Step, StepResponse>()
.Map(dest => dest.Id, src => src.Id.Value.ToString())
.Map(dest => dest.Type, src => src.Type.ToString());
When I map from one SelectionStep to StepResponse it's working
_mapper.Map<StepResponse>(SelectionStep)
When I map from List<Step> containing both SelectionStep and NumericStep models, it does not use the SelectionStepConfig.
_mapper.Map<List<StepResponse>>(List<Step>)

我找到了解决方案。
我将我的 Step 配置更改为包括 SelectionStep，请参见下面的新配置。
config.NewConfig<SelectionStep, StepResponse>()
.Map(dest => dest.Selections, src => src.Selections.Select(x => x.Value));
config.NewConfig<Step, StepResponse>()
.Include<SelectionStep, StepResponse>()
.Map(dest => dest.Id, src => src.Id.Value.ToString())
.Map(dest => dest.Type, src => src.Type.ToString());

I found the solution.
I changed my Step configuration to include the SelectionStep see below the new configs.
config.NewConfig<SelectionStep, StepResponse>()
.Map(dest => dest.Selections, src => src.Selections.Select(x => x.Value));
config.NewConfig<Step, StepResponse>()
.Include<SelectionStep, StepResponse>()
.Map(dest => dest.Id, src => src.Id.Value.ToString())
.Map(dest => dest.Type, src => src.Type.ToString());
