AutoMapper 的简单使用

var config = new MapperConfiguration(
cfg => cfg.CreateMap<SYS_Menu, MenuTreeNode>()
.ForMember(d => d.Id, opt => opt.MapFrom(s => s.MenuID)) //指定字段一一对应
.ForMember(d => d.Title, opt => opt.MapFrom(s => s.MenuName)) //指定字段一一对应
.ForMember(d => d.LinkUrl, opt => opt.MapFrom(s => s.NavigateUrl)) //指定字段一一对应
.ForMember(d => d.Children, opt => opt.MapFrom(s => s.Children))
);//指定字段，并转化指定的格式
var mapper = config.CreateMapper();

List<SYS_Menu> target = this.GetMenuTree(currentUserId);
List<MenuTreeNode> res = mapper.Map<List<MenuTreeNode>>(target);
