Correct me if I am wrong here

[Guest]

I am under the assumption that in vb.net the followin

Dim objClass as Object = Activator.CreateInstance(Type
Dim myClass as MyTestClass = DirectCast(objClass,MyTestClass

would be the equivalent o

Dim myClass as MyTestClass = New MyTestClas

Or do i need to add the following to CreateInstanc

Dim objClass as Object = Activator.CreateInstance(Type, New Object()
Dim myClass as MyTestClass = DirectCast(objClass,MyTestClass

Thank

Hi Joe,

Maybe I do not understand your question but to create an object from a class

Dim myClass as New MyTestClass

But correct me if I understand you wrong?

Dim objClass as Object = Activator.CreateInstance(Type)
Dim myClass as MyTestClass = DirectCast(objClass,MyTestClass)

would be the equivalent of

Dim myClass as MyTestClass = New MyTestClass

I doubt that this is equivalent. Why not use the 2nd method?

Or do i need to add the following to CreateInstance

If the code above works, no.

What are you talking about? Activator.CreateInstance calls the constructor
(in this case the default ctor ()) and returns the instance. How is this
different than the second??

The result is the same. Nevertheless, have a look at the IL using
"ILDASM.EXE".
