How do I find the dynamically type

[tony]

Hello!!

Assume I have this method
public void foo(object obj);
and I want to find out what type this obj is.
How do I do that?
I can look in the code but assume the code is very complicated.

assuming obj isn't null, then obj.GetType() will return you the Type object,
which gives you lots of info.
If possible, avoid == (or ReferenceEquals) on types (unless you really mean
it) - this is often a bug, as you should also check .IsSubclassOf().

Any use?

Hi,

Any object in .Net is derived from the root Object class. And Object has a
method named GetType that will do exactly what you want.

you can call obj.GetType().

.... or IsAssignableFrom.

Agreed - as this would handle interfaces correctly as well. I wasn't
thinking straight.
