如何在AutoMapper中使用.include（）？

Question

I'm implementing AutoMapper in my app to have different views for different needs. Until now I've more or less just used the DomainModel.

But when I use AutoMapper for my ViewModel, how do I then .Include() related data?

Startup.cs:

services.AddAutoMapper(typeof(AutoMapperProfiles));

AutoMapperProfiles.cs:

public class AutoMapperProfiles : Profile
{

    public AutoMapperProfiles()
    {

        Mapper.Initialize(cfg =>
        {
            cfg.CreateMap<Product, ProductVM>();
        });

        Mapper.Configuration.AssertConfigurationIsValid();

    }

}

My model:

public class Product
{
    public Guid id { get; set; }
    public string Name { get; set; }
    public Guid CategoryId { get; set; }
}

public class ProductVM
{
    public Guid id { get; set; }
    public string Name { get; set; }
    public Guid CategoryId { get; set; }
    [ForeignKey("CategoryId")]
    public ProductCategory ProductCategory { get; set; }
}

public class ProductCategory
{
    public Guid Id { get; set; }
    public string Name ( get; set; }
}

OnGet:

var products = await _dbContext.Products.ProjectTo<ProductVM>(_mapper.ConfigurationProvider).Include(x => x.ProductCategory).ToListAsync();

如果您的姓名完全匹配，请尝试以下操作：

CreateMap<Product, ProductVM>().ForMember(p => p.Tags, opt => opt.Ignore());
