c# - GetFields of derived type -

i trying reflect fields in derived type it's returning fields of base type.

public class basetype {     string basevar; }  public class derivedtype : basetype {     string derivedvar; } 

in function:

derivedtype derived = new derivedtype();  fieldinfo[] fields = derived.gettype().getfields(); 

this return basevar, not derivedvar. i've tried different bindings , doesn't seem make difference.

also, i'm doing in asp.net within app_code basevar defined in app_code , derivedvar user control defined in app_controls types not in scope.

as is, return nothing default binding public fields only.

as also, derivedtype isn't derived basetype

with:

fieldinfo[] fields = derived.gettype().getfields(bindingflags.nonpublic | bindingflags.instance); 

it returns derivedvar. i've checked in linqpad.

if change derivedtype derived basetype, can both fields with:

fieldinfo[] fields = derived.gettype().getfields(bindingflags.nonpublic | bindingflags.instance).concat(derived.gettype().basetype.getfields(bindingflags.nonpublic | bindingflags.instance)).toarray();
