我能实现在C＃中，从派生类拷贝“的拷贝构造函数”？我能、函数、派生类
这是应用具体的例子来说明我的眼前的问题：
An application specific example to illustrate my immediate problem:
我有一个元数据提供程序类具有以下（有删节）接口：
I have a metadata provider class with the following (abridged) interface:
public class CtsDataAnnotationsModelMetadataProvider : DataAnnotationsModelMetadataProvider
{
protected override ModelMetadata CreateMetadata(IEnumerable<Attribute> attributes, Type containerType, Func<object> modelAccessor, Type modelType, string propertyName)
{
var metadata = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);
return metadata;
}
}
现在我想延长 ModelMetadata 具有附加属性，这些填充并返回和 ExtendedModelMetadata 的实例。我怎样才能很好地传达我的延长例如通过 base.CreateMetadata 分配给元实例属性？我想，但没有为;
Now I would like to extend ModelMetadata with additional properties, populate these and return and instance of ExtendedModelMetadata. How can I nicely convey properties assigned to the metadata instance by base.CreateMetadata in my extended instance? What I would like but don't have is;
var metadata = (ExtendedModelMetadata)base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);
我可以创建一个构造 ExtendedModelMetadata ，需要一个 ModelMetadata 参数，并明确赋予它的所有属性的比如正在建设中，但我想这一个更通用和更少的硬件codeD的方法。我该怎么办？
I can create a constructor for ExtendedModelMetadata that takes a ModelMetadata parameter and explicitly assigns all of it's properties to the instance being constructed, but I would like a more generic and less hard-coded approach for this. What can I do?
推荐答案
您可以使用 AutoMapper 实现这一目标。
You can use AutoMapper to achieve this.
Mapper.CreateMap<ModelMetaData , ExtendedModelMetadata>();
.NET Framework不提供了深刻的复印功能。
.NET Framework does not provide a deep copy feature.
