Create object at runtime.. is reflection needed?

[Jay Allard]

Hello

I'm sure this is already posted somewhere, I'm just not using the
correct search words or something.

Anyway, I want to store a class name in a database:
TestApplication.Validators.MyCustomClass
(MyCustomClass is the class name).

MyCustomClass implements an interface named IValidator. I know that
every class specified in the database will implement that interface.
Knowing that, is it possible to dynamically create the object, or do I
have to use reflection?

I'm looking for something like

IValidator v = something.something("TestApplication.Validators.MyCustomClass");
so I can then use the methods defined in the IValidator interface.

v.SetAProperty("whatever");
v.Validate();

Is that possible, or do I have to use reflection and InvokeMember for
each method?

Thanks

Jay

Hi Jay,

Activator.CreateInstance Method does just that.

Perfect. Thanks.

In case anyone else comes across this, here's the actual code I used.

System.Runtime.Remoting.ObjectHandle oh =
Activator.CreateInstance(sValidationAssembly, sValidationClass);
WhatTypeOfObjectItIs x = (WhatTypeOfObjectItIs)oh.Unwrap();
