Reflecting methods

[billsahiker]

How can I use reflection to inspect any assembly and get only the
methods written by the developers of the assembly, not all the built-
in methods. When I use GetMethods on the Module, it returns all the
built-in methods, so for a Form, I get
get_autosize, get_autoscroll, which I do not want. How can I filter
those out? I read the documentation and looked into bindingflags and
tried many other options but cannot find anything that does what I
need. Using framework 2.0 and vs2005. Please excuse if this is posted
twice -I got a google server error first time, so am sending again.

BindingFlags.DeclaredOnly is the flag you should be using.

I can get all the types in the assembly, but using the declaredonly
flag returns an empty memberInfo array. I tried the following code on
several projects, each with one form and one class. A button_click in
the form creates an instance of the public class and calls one of its
public methods. These projects compile and run without error.

Dim a As Assembly = Assembly.LoadFrom(Path)
Dim alltypes as Type = a.GetTypes
For each t As Type in alltypes
lstTypes.Items.Add(t.Name)
Dim mems() as MemberInfo = t.GetMembers(BindingFlags.DeclaredOnly)
For each m as MemberInfo in mems
lstMethods.Items.Add(m.Name)
Next

Specifying only DeclaredOnly is not sufficient. You have to combine it
with other BindingFlags to say exactly what you want (Public,
NonPublic, Static, Instance etc).
