http://blogs.msdn.com/haibo_luo/archive/2006/07/09/661091.aspxAs John mentioned in his post , every Reflection user should keep this in mind: our code should not count on the member order returned by GetFields, GetMethods and other similar GetXXXs calls. Given two fields (F1, F2) in one type, I think the compileren-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/haibo_luo/archive/2006/07/09/661091.aspx#661174Mon, 10 Jul 2006 11:26:52 GMT91d46819-8472-40ad-a661-2c78acb4018c:661174Jeroen FrijtersHi, <br> <br>While I appreciate (and agree with) this point, it does remind me of the fact that sometimes you need a more accurate window into the metadata and it is unfortunate that Reflection doesn't provide that option. Here are a couple of examples: <br>- For types that have LayoutKind.Sequential, the order of the fields is significant and it would be nice to have a way to return the fields in the right order. <br>- For COM interop method order can be significant, but there is no way to get the methods in declaration order. <br>- In my Java runtime, I would like to have the ability to query what interfaces a type implements *directly* (and in what order), but this is currently not possible. <br> <br>I know that there are low level (unmanaged) metadata APIs, but they are more difficult to use and don't work in conjunction with dynamically generated Ref.Emit code. <br>http://blogs.msdn.com/haibo_luo/archive/2006/07/09/661091.aspx#661288Mon, 10 Jul 2006 13:38:14 GMT91d46819-8472-40ad-a661-2c78acb4018c:661288CoqBlogHaibo Luo nous livre un post int&amp;#233;ressant dans lequel il insiste sur le fait que nous ne pouvons faire...http://blogs.msdn.com/haibo_luo/archive/2006/07/09/661091.aspx#661924Tue, 11 Jul 2006 06:31:03 GMT91d46819-8472-40ad-a661-2c78acb4018c:661924Haibo_LuoJeroen - thanks for your comment.

In the humongus amount of information we can get from reflection I can't understand how FieldInfo definition order was discarded. At leas we should always be able to get the FieldOffsetAttribute out of the FieldInfo object. <br> <br>In answer to Jeroen Frijters, you can get Com members in the correct order using Marshal.GetMethodInfoForComSlot, Marshal.GetStartComSlot and Marshal.GetEndComSlot. <br> <br>Still can't understand how am I going to solve the field order problem though. :) <br> <br>Regards, <br>Jo&#227;o N&#243;brega.http://blogs.msdn.com/haibo_luo/archive/2006/07/09/661091.aspx#4175190Wed, 01 Aug 2007 22:41:07 GMT91d46819-8472-40ad-a661-2c78acb4018c:4175190Joshua Melcon<p>The order of field definitons within classes is important metadata.
