Dynamic casting

[Val]

Hi

I am using a DynamicProxy (class that inherits from RealProxy). I don't know the type of my Transparant Proxy at compile time. Is there a possibility to have a dynamic casting

object[] correctParams = new object[x]
for(int i...

Type t = Type.GetType(ti B.GetTypeName() )
DynamicProxy proxy = new DynamicProxy(t, orderedParams[i], tiA)
correctParams[i] = /*TODO: CAST into type t*/ proxy.GetTransp arentProxy()
I would like to cast the result of proxy.GetTransp arentProxy() into the type t. Is it possible

Thanks a lo

into the type t. Is it possible?

What difference would it make? correctParams is just an array of object
references - why would you need to cast the reference?

I need to use the methods contained in the Type t on the objects of correctParams in the rest of the code. If these object are just object, I will only be able to use the methods of the class object (GetType, GetHashCode, ...

But casting where you suggested casting wouldn't do you any good
anyway. Actually, it would check that the cast it valid, but that's
all.

If you don't know the type in advance, you won't be able to use the
methods in your code anyway, will you? If you know that the type will
have certain methods, then build an interface with those methods, make
the type implement those methods, and cast to the interface when you
need to.

Yes, you are right, I was a little bit confused. Thanks for your hel
