Automapper 5.0.2 - 缺少类型映射配置或不支持的映射

Question

我已经阅读了所有我能在网上找到关于这个问题的内容,但没有任何帮助.这是我的代码:

 Mapper.Initialize(cfg =>
        {
            cfg.CreateMap<User, UserListViewModel>()
            .ForMember("RoleNames", c => c.Ignore())
            .ForMember("CostCentreNames", c => c.Ignore())
            .ForMember("RollupGroupNames", c => c.Ignore())
            .ForMember(c => c.CostCentres, m => m.MapFrom(d => d.DetailCostCentres))
            ;
        });

        Mapper.Initialize(cfg =>
        {
            cfg.CreateMap<CostCentre, CostCentreListViewModel>();

        });

var users = _repo.AllIncluding(u => u.Roles, u=>u.CostCentres).OrderBy(u => u.UserName).ToList();
var  model = Mapper.Map<List<User>, List<UserListViewModel>>(users);

Mapper.Map给了我错误:

缺少类型映射配置或不支持的映射.

映射类型:
User - > UserListViewModel
Model.Models.User - > Model.ViewModels.UserListViewModel

你只能打一个Mapper.Initialize电话:

 Mapper.Initialize(cfg =>
        {
            cfg.CreateMap<User, UserListViewModel>()
            .ForMember("RoleNames", c => c.Ignore())
            .ForMember("CostCentreNames", c => c.Ignore())
            .ForMember("RollupGroupNames", c => c.Ignore())
            .ForMember(c => c.CostCentres, m => m.MapFrom(d => d.DetailCostCentres));
            cfg.CreateMap<CostCentre, CostCentreListViewModel>();
        });
