实例属性＆＃39;项目（KeyValuePair`2）＆＃39;未定义类型＆＃39; System.Collections.Generic.Dictionary`2 [System.Object，System.Object]＆＃39;

Question

我的AutoMapper配置文件中有以下映射，它正在运行：

CreateMap<KeyValuePair<int, string>, SelectListItem>()
    .ForMember(m => m.Selected, opt => opt.Ignore())
    .ForMember(m => m.Text, opt => opt.MapFrom(c => c.Value))
    .ForMember(m => m.Value, opt => opt.MapFrom(c => c.Key.ToString()));

CreateMap<KeyValuePair<short, string>, SelectListItem>()
    .ForMember(m => m.Selected, opt => opt.Ignore())
    .ForMember(m => m.Text, opt => opt.MapFrom(c => c.Value))
    .ForMember(m => m.Value, opt => opt.MapFrom(c => c.Key.ToString()));

更新到Veriosn 5.1.1后，我在AutoMapper初始化中收到以下错误：

Instance property 'Item(KeyValuePair`2)' is not defined for type 'System.Collections.Generic.Dictionary`2[System.Object,System.Object]'

通过评论上面的地图线，我不再感到错误，但我需要它们 我该如何解决？
