Type.GetFields Method (BindingFlags)
-
Thanks Senthil, I have written a test case, I am using a base class type variable to point to a derived type and in the derived type, I override a method of base class. But it seems I can get nothing in variable fields. Any ideas?
class Program { class Foo { public static int abc; virtual public void bcd() { } } class Goo : Foo { override public void bcd() { } } static void Main(string\[\] args) { Foo f = new Goo(); FieldInfo\[\] fields = f.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public); return; } }regards, George

The text in the MSDN page is for people deriving from
System.Type, for whatever reason. From a user's perspective, it returns the list of fields in the class represented by the Type.Regards Senthil [MVP - Visual C#] _____________________________ My Blog | My Articles | My Flickr | WinMacro

Thanks Senthil, The fields only for member variables, not for functions? regards, George

GetFields returns only fields (member variables) in that type. Type.GetMethods[^] returns functions defined in that Type.

Every single type defined derives from Type as a RuntimeType.
xacc.ide - now with TabsToSpaces support
IronScheme - 1.0 alpha 4a out now (29 May 2008)For any user defined class, does the class implicitly derives from Type? regards, George

Call GetMembers then.

IronScheme - 1.0 alpha 4a out now (29 May 2008)I have tested it, leppie! Looks like GetMembers is more powerful than GetFields. :-) regards, George

Thanks Senthil, Looks like GetMembers return both methods and fields, and GetMethods/GetFields returns just method/field? So, GetMembers is more powerful. :-) regards, George

The field abc is defined as static, but in your GetFields() call you ask it to return only instance fields.
Thanks Vega02, I think the root cause is, I do not know GetFields will not return methods before. :-) regards, George
