c# Automapper - 如何在 objetc 中 map object

Question

I want to mapper these two object,

public class UpdateCostDto
{        
    public string JobId { get; set; }
    public bool IsSpreadSucceeded { get; set; }
    public DateRange CostPeriod { get; set; }        
}

public class DateRange
{
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
}





 public class UpdateCost11
{
    public string JobId { get; set; }
    public bool IsSpreadSucceeded { get; set; }
    public DateRange CostPeriod { get; set; }
}

public class DateRange
{
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
}

I createMap: CreateMap<UpdateCost11, UpdateCostDto>(); CreateMap<UpdateCostDto, UpdateCost11>();

but I get an error: "Error mapping types.

Mapping types: UpdateCostSpreadStatusMessageDto -> UpdateCostSpreadStatusDto AnalyticsService.Models.IndeedQueueMessage.UpdateCostSpreadStatusMessageDto -> AnalyticsService.Models.UpdateCostSpreadStatusDto

Type Map configuration: UpdateCostSpreadStatusMessageDto -> UpdateCostSpreadStatusDto AnalyticsService.Models.IndeedQueueMessage.UpdateCostSpreadStatusMessageDto -> AnalyticsService.Models.UpdateCostSpreadStatusDto

Destination Member: CostPeriod "

Answer 1

You need to add your DateRange models to your mapper profile.

CreateMap<namespace1.DateRange, namespace2.DateRange>().ReverseMap();

Depending on which version you are using you can also use .ReverseMap() instead of explicitly creating a map for the reverse mapping.

CreateMap<UpdateCost11, UpdateCostDto>().ReverseMap();

Even though the classes DateRange on Dto and your main class have the same structure, their namespace is different. And auto-mapper won't map it as you want.

You either have to delete one of the DateRange classes and go with one of them or as @Hamlet Hakobyan suggested, you have to add the following configuration

CreateMap<SourceNameSpace.DateRange, DestinationNameSpace.DateRange>();

Change SourceNameSpace and DestinationNameSpace to the one you have.
