.NET Forum / Languages / C# / August 2006How do I find the dynamically type
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. //Tony 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?

I wasn't thinking straight. Cheers Marc Hi, > 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? 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.
