【.NET 生态】AutoMapper

AutoMapper 是一个对象转换映射工具，可以将一个对象的属性映射到另外一个对象上。

最佳实践

封装成泛型扩展方法（不用提前配置）

public static TDestination MapTo<TDestination, TSource>(this TSource source)
    where TDestination : class
    where TSource : class
{
    if (source == null) return default(TDestination);
    var config = new MapperConfiguration(cfg => cfg.CreateMap<TSource, TDestination>());
    var mapper = config.CreateMapper();
    return mapper.Map<TDestination>(source);
}

public static IEnumerable<TDestination> MapToList<TSource, TDestination>(
    this IEnumerable<TSource> source)
    where TDestination : class
    where TSource : class
{
    if (source == null) return new List<TDestination>();
    var config = new MapperConfiguration(cfg => cfg.CreateMap<TSource, TDestination>());
    var mapper = config.CreateMapper();
    return mapper.Map<List<TDestination>>(source);
}
