hello everyone,
is there any way in C# to perform dynamic property discovery? i know
such a thing was possible in C++ template code, but it was kind of an
ugly mess. i'm just curious if there is a way to do such a thing in C#,
not suggesting that C# should be able to do things that C++ did (no
need to start any wars here)
for example, if i have:
public class MyClass
{
MyClass() { }
public int P1;
public string P2;
}
can i somehow discover these properties at runtime? such as:
MyClass obj = new MyClass();
// #discovery psuedo-code:
// for each property in obj do
Console.WriteLi ne(Convert.ToSt ring(/*property*/));
thanks for any help!

Is this what you're wanting?
Type f = typeof(MyClass) ;
PropertyInfo[] properties = f.GetProperties ();
foreach (PropertyInfo property in properties)
{
Console.WriteLi ne(property.Nam e);
}

Yes, very easily. Google for C# and Reflection.

Sure, look at "reflection " in the c# documentation, or on
codeproject.com . You should find everything you need there. If you need
an example, let me know, and I'll go dig one up.

Thanks a lot. This is indeed exactly what I was looking for. No need
for examples, but thanks! By the way, do you know if by chance this can
be exposed through COM Interop? I'm probably getting too optimistic,
but if there's a way that we can use reflection in ASP classic, that
would be awesome.
I suppose I could whip up a class that accepted an object reference and
reported the reflection information easily enough. Except that I don't
think my previous attempts to pass an object reference from ASP Classic
into a COM Interop object method have been very successful.
Thanks again for this info though! Even if we can only use it in our
..NET-only apps, this is very useful!
exactly what i was looking for. thanks!
do you by chance have any experiences trying to expose this
functionality through COM Interop? this would be even more useful if we
could access it in ASP Classic somehow. i have another comment
elsewhere in this thread on this line of questioning if you're
interested.
thanks a lot!

Reflection should be available in any .NET language. I'm not an ASP
guy, but I'm pretty sure I saw some examples of reflection with ASP
when I was doing research for it originally.

Hi there,
Is it possible to load a web service dynamically? i.e. If the web
service were to exist on a system with a non static IP address, an
application could download a "locator" file that contained details of it's
whereabouts, I have been looking at the "Discovery.DynamicDiscoveryDocument"
class but I think think this is what I am looking for is it? Thanks in
advance.
Nick.

We have an application converted from v1.1 Framework to v2.0. The executable

this worked well. Unfortunately, this is not working under the 2.0 framework.

I have a web service that has been working, but I recently changed it
so that the reference would be dynamic. Locally, within Visual Studio,
it works fine. However, once deployed, the dll I use to access it has

the change to dynamic url.
I noticed in the discovery file and the wsdl file that the old
