Question

当我读到“ASP_NET-MVC-5-with-Bootstrap-and-Knockout_js”这本书时，无法编译自爆代码

AutoMapper.Mapper.CreateMap(_sourceType, _destinationType);

如果我根据新版本指南修改 Mapper.Initialize（cfg =＆gt; cfg.CreateMap＆lt; _sourceType，_destinationType＆gt;（）），则会出现此错误：严重性代码说明项目文件线路抑制状态错误CS0246找不到类型或命名空间名称'_sourceType'（您是否缺少using指令或程序集引用？）谁能帮我提一些建议？

namespace BootstrapIntroduction.Filters {
    [AttributeUsage(AttributeTargets.Method)] 
    public class GenerateResultListFilterAttribute : FilterAttribute, IResultFilter {
        private readonly Type _sourceType;   
        private readonly Type _destinationType;

        public GenerateResultListFilterAttribute(Type sourceType, Type destinationType) {
            _sourceType = sourceType;
            _destinationType = destinationType;
        }

        public void OnResultExecuting(ResultExecutingContext filterContext) {
            var model = filterContext.Controller.ViewData.Model;

            var resultListGenericType = typeof(ResultList<>).MakeGenericType(new Type[] { _destinationType });
            var srcGenericType = typeof(List<>).MakeGenericType(new Type[] { _sourceType });
            var destGenericType = typeof(List<>).MakeGenericType(new Type[] { _destinationType }); 

            AutoMapper.Mapper.CreateMap(_sourceType, _destinationType);
            var viewModel = AutoMapper.Mapper.Map(model, srcGenericType, destGenericType);

            var queryOptions = filterContext.Controller.ViewData.ContainsKey("QueryOptions") ? 
                      filterContext.Controller.ViewData["QueryOptions"] : new QueryOptions();

            var resultList = Activator.CreateInstance(resultListGenericType, viewModel, queryOptions);

            filterContext.Controller.ViewData.Model = resultList;  
        }

        public void OnResultExecuted(ResultExecutedContext filterContext) {
        }  
    }

我发现有人也有同样的问题，但没有回答：http://www.endyourif.com/integrating-automapper-with-an-mvc-result-filter/

AutoMapper.Mapper.CreateMap已过时
