Question

我目前正在实施WebApi。我基本上需要填充数据库中的所有产品并使用EntityFramework数据库First Approach。我需要在提供程序类中自动化我的Buisness对象和Data对象。无论如何，我收到以下错误

Missing type map configuration or unsupported mapping.\r\n\r\nMapping types:\r\nProducts -> Products\r\nProductManagement.DataOjects.Entities.Products -> 
ProductManagement.Models.Products\r\n\r\nDestination path:\r\nIEnumerable`1[0]\r\n\r\nSource value:\r\nProductManagement.DataOjects.Entities.Products"}

这是我的数据对象

namespace ProductManagement.DataOjects.Entities
{
    public class Products
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public string Code { get; set; }

        public DateTime ReleaseDate { get; set; }
      }
 }

这是我的商业对象

namespace ProductManagement.Models
{
    public class Products
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public string Code { get; set; }

        public DateTime ReleaseDate { get; set; }
     }
}

这是我的存储库类，它使用linq来获取数据

public class ProductRepository : IProductRepository
    {
        public IEnumerable<ProductManagement.DataOjects.Entities.Products> GetProductData()
        {
            using (var dbProductEntities = new ProductManagement.DataOjects.Ef.RansangEntities())
            {
                return (from a in dbProductEntities.vw_Products
                        select new ProductManagement.DataOjects.Entities.Products
                        {
                            Id = a.Id,
                            Name = a.Name,
                            Code = a.Code,
                            ReleaseDate = (DateTime)a.ReleaseDate

                        }).ToList().AsEnumerable();
            }
        }


    }

这是我的Provider类，我实现了Automapper

 public class ProductProvider : IProductProvider
    {
        private readonly  IProductRepository _productRepository;


        public ProductProvider(IProductRepository productRepository)
        {
            _productRepository = productRepository ;
        }

        public IEnumerable<Products> GetProductData()
        {
            var productData = _productRepository.GetProductData();
            var productViewData = AutoMapper.Mapper.Map<IEnumerable<ProductManagement.DataOjects.Entities.Products>, IEnumerable<ProductManagement.Models.Products>>(productData);
            return productViewData;

        }


    }

有人能说出问题是什么吗？

你需要把它写成你的模型类：

公共类产品：IMapFrom＆lt; YourBusnessEntityToMap＆gt;

现在它会正常工作。：）

自动映射错误 - 缺少类型映射配置或不支持的映射
