Hello,

I would like to know if it's possible using reflection to loop through
all "web references" of a given assembly and get the url as specified
in the web.config (dynamic url behavior).

Something like

for each objWebRef in [Assembly].GetWebReferences
Msgbox(objWebRef.url)
next

Thanks,
Alex

Web references don't really work like that - they're just autogenerated
proxy classes which are built into the "main" assembly.

Yes I am aware of that... so basically, I am looking for a way to loop
through those "autogenerated proxy classes" to get the URL...

If I take the problem differently.. how can I distinguish between a
normal class and a "autogenerated proxy class"? Using reflection, can
I do a loop on classes that inherits from
"System.Web.Services.Protocols.SoapHttpClientProtocol"?

If so, how?

Thanks,
Alex

Absolutely. Use Type.IsSubclassOf or Type.IsAssignableFrom. Of course,
there could be other subclasses there, but it's a reasonable
indication...

If I try that :
Dim objClasse As Type
For Each objClasse In
[Assembly].GetExecutingAssembly.GetTypes()
Response.Write("// " & objClasse.Name & vbcrlf)
If
objClasse.IsAssignableFrom(GetType(System.Web.Services.Protocols.SoapHttpClientProtocol))
Then
Response.Write("// WebService! " & objClasse.Name
& vbcrlf)
End If
Next

No proxy class shows up... as if they are not returned by "GetTypes()"

Is there another way to loop through classes?

Thanks,
Alex

IsAssignableFrom works the other way round. You should call it on the
SoapHttpClientProtocol type, passing in objClasse.

Thank you Jon, it works perfectly.

Here's my final code :

Dim objType As Type
Dim objWS As
System.Web.Services.Protocols.SoapHttpClientProtocol

For Each objType In
[Assembly].GetExecutingAssembly.GetTypes()

If
GetType(System.Web.Services.Protocols.SoapHttpClientProtocol).IsAssignableFrom(objType)
Then

'// The class is a webservice
objWS = Activator.CreateInstance(objType)

MsgBox("WebService : " & objType.Name & " - """ &
objWS.Url & """")
End If
Next
