The only infromation about ignoring many of members is this thread - http://groups.google.com/group/automapper-users/browse_thread/thread/9928ce9f2ffa641f . I think you can use the trick used in ProvidingCommonBaseClassConfiguration to ignore common properties for similar classes. And there is no information about the "Ignore the rest" functionality. I've looked at the code before and it seems to me that will be very and very hard to add such functionality. Also you can try to use some attribute and mark with it ignored properties and add some generic/common code to ignore all marked properties.

我已经能够做到这一点的方式如下:

Mapper.CreateMap<SourceType, DestinationType>().ForAllMembers(opt => opt.Ignore());
Mapper.CreateMap<SourceType, DestinationType>().ForMember(/*Do explicit mapping 1 here*/);
Mapper.CreateMap<SourceType, DestinationType>().ForMember(/*Do explicit mapping 2 here*/);
...

注意:我使用的是AutoMapper v.2.0。

在3.3.1版本中，您可以使用IgnoreAllPropertiesWithAnInaccessibleSetter()或IgnoreAllSourcePropertiesWithAnInaccessibleSetter()方法。

我更新了Robert Schroeder对AutoMapper 4.2的答案。对于非静态映射器配置，我们不能使用mapper . getalltypemaps()，但表达式有一个对所需的TypeMap的引用:

public static IMappingExpression<TSource, TDestination> 
    IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
    foreach (var property in expression.TypeMap.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

对于那些使用4.2.0及以上版本的非静态API的人，可以使用以下扩展方法(在AutoMapperExtensions类中找到):

// from http://stackoverflow.com/questions/954480/automapper-ignore-the-rest/6474397#6474397
public static IMappingExpression IgnoreAllNonExisting(this IMappingExpression expression)
{
    foreach(var property in expression.TypeMap.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

这里重要的是，一旦删除了静态API，像Mapper这样的代码。FindTypeMapFor将不再工作，因此要使用表达式。TypeMap字段。

我已经更新了Can Gencer的扩展，不覆盖任何现有的地图。

public static IMappingExpression<TSource, TDestination> 
    IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
    var sourceType = typeof (TSource);
    var destinationType = typeof (TDestination);
    var existingMaps = Mapper.GetAllTypeMaps().First(x => x.SourceType.Equals(sourceType) && x.DestinationType.Equals(destinationType));
    foreach (var property in existingMaps.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

用法:

Mapper.CreateMap<SourceType, DestinationType>()
                .ForMember(prop => x.Property, opt => opt.MapFrom(src => src.OtherProperty))
                .IgnoreAllNonExisting();

更新:注意，在9.0版本Mapper静态API被删除
