AutoMapping实体到模型

Question

我试着绘制这些地图，但我得到了

AutoMapper.AutoMapperMappingException：“缺少类型映射配置或不支持映射。”

public class MenuItemViewModel
{
    [Required]
    public string Text { get; set; }
    public string URL { get; set; }
    public string Icon { get; set; }
    public IList<MenuItemViewModel> Children { get; set; }
    public MenuItemViewModel Parent { get; set; }
    public int Sort { get; set; }
}

public class MenuItem
{
    public Guid Id { get; set; }
    public string Text { get; set; }
    public string URL { get; set; }
    public string Icon { get; set; }
    public IList<MenuItem> Children { get; set; }
    public MenuItem Parent { get; set; }
    public bool onMenu { get; set; }
    public int Sort { get; set; }

    public IList<MenuItemPermittedRole> MenuItemPermittedRoles { get; set; }
}

Mapper.Initialize(cfg => {
    cfg.CreateMap<MenuItem, MenuItemViewModel>().ReverseMap();
});

MenuItemViewModel result = Mapper.Map<MenuItemViewModel>(menuItems); ERROR HERE

如果不知道你到底收到了什么错误，就很难回答，但我能猜到.如果menuItems是IEnumerable<MenuItem>，则应该编写

var result = Mapper.Map<IEnumerable<MenuItemViewModel>>(menuItems);
