如何忽略被标记为虚拟的所有属性 [英] How to ignore all properties that are marked as virtual

问题描述

我使用虚拟关键字一些我的EF延迟加载特性。我有这样的情况，这在我的模型的所有属性标记为虚拟应该映射源到目的地时，从AutoMapper忽略。

I am using virtual keyword for some of my properties for EF lazy loading. I have a case in which all properties in my models that are marked as virtual should be ignored from AutoMapper when mapping source to destination.

是否有自动的方式，我可以做到这一点，或者我应该手动忽略每一个成员？

Is there an automatic way I can achieve this or should I ignore each member manually?

推荐答案

您可以创建一个映射的扩展和使用它：

namespace MywebProject.Extensions.Mapping
{
    public static class IgnoreVirtualExtensions
    {
        public static IMappingExpression<TSource, TDestination>
               IgnoreAllVirtual<TSource, TDestination>(
                   this IMappingExpression<TSource, TDestination> expression)
        {
            var desType = typeof(TDestination);
            foreach (var property in desType.GetProperties().Where(p =>   
                                     p.GetGetMethod().IsVirtual))
            {
                expression.ForMember(property.Name, opt => opt.Ignore());
            }

            return expression;
        }
    }
}

用法：

Mapper.CreateMap<Source,Destination>().IgnoreAllVirtual();
