c# – 防止Automapper将IEnumerable属性转换为List

这些是我想要映射的类：

BasicOverview
{
   public IRichTextContent Intro { get; set; }
   ...
}

BlogOverviewViewModel
{
   public IRichTextContent Intro { get; set; }
   ...
}

以下是定义IRichTextContent类型的第三方代码：

//     Represents rich text content in a form of structured data
public interface IRichTextContent : IEnumerable<IRichTextBlock>,IEnumerable
{
    //
    // Summary:
    //     List of rich text content blocks
    IEnumerable<IRichTextBlock> Blocks { get; set; }
}

我的Automapper配置文件：

public AutomapperProfile()
    {
        CreateMap<BasicOverview,BlogListViewModel>();
        CreateMap<BasicOverview,ReviewListViewModel>();
        CreateMap<BasicOverview,BlogOverviewViewModel>();
    }

这是我得到的错误：

An unhandled exception occurred while processing the request.
InvalidCastException: Unable to cast object of type ‘System.Collections.Generic.List`1[KenticoCloud.Delivery.IRichTextBlock]’ to type ‘KenticoCloud.Delivery.IRichTextContent’.
lambda_method(Closure,BasicOverview,BlogOverviewViewModel,ResolutionContext )

AutoMapperMappingException: Error mapping types.

Mapping types:
BasicOverview -> BlogOverviewViewModel

Type Map configuration:
BasicOverview -> BlogOverviewViewModel

Destination Member:
Intro
lambda_method(Closure,ResolutionContext )

我尝试将以下内容添加到我的Automapper配置文件中：

CreateMap<IEnumerable<IRichTextBlock>,IRichTextContent>()
            .ForMember(dest => dest.Blocks,m => m.MapFrom(src => src));

其中产生了以下错误：

TypeLoadException: Method ‘GetEnumerator’ in type ‘Proxy_KenticoCloud.Delivery.IRichTextContent_12345678_’ from assembly ‘AutoMapper.Proxies,Version=0.0.0.0,Culture=neutral,PublicKeyToken=abc123ef45’ does not have an implementation.
