Type.GetMembers()
-
I've been using System.Reflection a lot for my custom serializer/deserializer classes, and I'm really digging it. It has made a lot of it pretty easy. So I've been using
obj.GetType().GetMembers(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)to get all the members I care about -- fields and properties. What's weird, though, is that GetMembers() isn't returning the type's inherited members. I expect it should, and I believe that a few days ago it was. I'm not using any other binding flags, especially not one that would limit the search to just members declared in the immediate type. Am I doing something wrong, or is the expected usage of GetMembers() that I'd have to iteratively traverse the inheritance tree and GetMembers() of each inherited type? Thanks, Arun -

BindingFlags.DeclaredOnlyis set, you should be seeing all inheritted, yes. May I ask how you determined that the inherited members weren't being returned? Perhaps surrounding code would be helpful.-----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Right. I'm definitely not using BindingFlags.DeclaredOnly. I know that inherited members aren't being returned because they're not being serialized (the output is XML), and I can even check by stepping through with a debugger. I'm not at work right now, but the code is basically:
MemberInfo[] members = obj.GetType().GetMembers(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance); foreach (Member member in members) { if (member is FieldInfo) { ... } else if (member is PropertyInfo) { ... } }Inside each block, I store the member if the conditions are proper. But even if I remove those conditions, I'm still only getting the non-inherited types. I'm a little concerned that a previous version of my assembly is being used. I'll check for that on Monday, but again, I doubt that's the case since I was even stepping through with VS. -

Well, it looks like I can't get access to private fields of inherited types through GetMembers(). I guess that makes sense. Using Reflector, I see that System.Runtime.Serialization also has to ascend the inheritance tree to get the list of serializable members, so I will, too. Thanks, Arun
