错误
缺少类型映射配置或不支持的映射。映射类型:CategoriesViewModel-> Categoies_7314E98C41152985A4218174DDDF658046BC82AB0ED9E1F0440514D79052F84D NewsCMS.Areas.Admin.Models.categoryViewModel-> System.Data.Entity.DynamicProxies.Categoies_7314E98C41152985A4218174DF4
目标路径:Categoies_7314E98C41152985A4218174DDDF658046BC82AB0ED9E1F0440514D79052F84D
源值:NewsCMS.Areas.Admin.Models.CategoriesViewModel
我想念什么?我尝试查找,但是看不到问题。
更新
我已经在Global.asax的application_start中指定了
protected void Application_Start()
{
InitializeAutoMapper.Initialize();
}
InitializeClass
public static class InitializeAutoMapper
{
public static void Initialize()
{
CreateModelsToViewModels();
CreateViewModelsToModels();
}
private static void CreateModelsToViewModels()
{
Mapper.CreateMap<Categoies, CategoriesViewModel>();
}
private static void CreateViewModelsToModels()
{
Mapper.CreateMap<CategoriesViewModel, Categoies>()
.ForMember(c => c.CategoryPositions, option => option.Ignore())
.ForMember(c => c.Posts, option => option.Ignore());
}
}
