c# - Automapper 无法翻译通用列表

Question

我有两个要映射的以下类的集合:

 public class Client_Crime_ViewModel
    {
       public Client_Crime_ViewModel() { }

        public Client_Crime_ViewModel(CrimeIncident ci)
        {
            Id = ci.Id;
            CaseNumber = ci.CaseNumber;
            DateOfIncident = ci.DateOfIncident;
            Description = ci.Description;
        }

        public Int64 Id
        {
            get;
            set;
        }

        [Required]
        [DisplayName("Case Number")]
        public string CaseNumber { get; set; }

        [DataType(DataType.Date)]
        [Required]
        [DisplayName("Date of Incident")]
        public string DateOfIncident { get; set; }

        [DataType(DataType.MultilineText)]
        [Required]
        public string Description { get; set; }
    }



public class CrimeIncident
    {
        public Int64 Id { get; set; }

        [Required]
        public string CaseNumber { get; set; }

        [Required]
        public string Description { get; set; }

        [DataType(DataType.Date)]
        public string DateOfIncident { get; set; }

        public CrimeIncident() { }

        public CrimeIncident(string caseNumber, string dateOfIncident, string description)
        {
            CaseNumber = caseNumber;
            Description = description;
            DateOfIncident = dateOfIncident;
        }
    }

我尝试过以下两种方式进行映射:

方法一:

Mapper.CreateMap<List<Client_Crime_ViewModel>, List<CrimeIncident>>();
List<Client_Crime_ViewModel> cvmList = System.Web.Helpers.Json.Decode<System.Collections.Generic.List<Client_Crime_ViewModel>>(rb.Form["CrimeCollection"]);
List<CrimeIncident> ciList = Mapper.Map<List<Client_Crime_ViewModel>, List<CrimeIncident>>(cvmList);

方法二:

Mapper.CreateMap<List<Client_Crime_ViewModel>, List<CrimeIncident>>();
List<Client_Crime_ViewModel> cvmList = System.Web.Helpers.Json.Decode<System.Collections.Generic.List<Client_Crime_ViewModel>>(rb.Form["CrimeCollection"]);
List<CrimeIncident> ciList = Mapper.Map<List<CrimeIncident>>(cvmList);

这两种方法都失败了。调试显示，尽管 cvmList 的元素计数为 > 0，但 ciList 的元素计数仍为 0。

知道我做错了什么吗？提前致谢。

Answer 1

您不需要为列表创建映射，只需映射实体即可。
