Question

我试图回答目前使用反思的提问:

var dbObjects = from d in collection  
    where d.GetType().GetProperty("Id").GetValue(d, null) == id  
    select d;

I would like to use dynamic typing to access the property Id on "d" without knowing what type "d" is at compile time. Something like this:

var dbObjects = from (dynamic)d in collection  
    where d.Id == id  
    select d;

Is this possible? ... and out of interest, is it faster, or does the dynamic runtime use reflection under the hood?

感谢

活力型的反思在一生中使用,因此,如果存在的话,它就算得更快。因此,我认为你的林克-To-Sql语应当作罚款。 http://www.hanselman.com/blog/C4AndTheDynamicKeywordWhirlwindTourAroundNET4AndVisualStudio2010Beta1.aspx” rel=“nofollow noretinger”。德国航天中心只能使你的法典更加可读。
