Hi,
I need to design a method that creates and returns a large array of
objects. The problem is that the *type* of object to create isn't know until
runtime. As a result, a parameter of type "Type" must be passed in:
IMyInterface CreateObjects(Type type,int numberOfObjects);
Internally this method will call Activator.CreateInstance() to create
the objects. Here's my question: Is there a significant performance penalty

I have the following code which works fine.
However I want to pass the object I'm instantiating a string for its
constructor.
I can't get the syntax right. Can someone give me an example of
Activator.CreateInstance where they pass an argument with the object type?
Assembly a = Assembly.GetExecutingAssembly();
Type type = a.GetType("MyAssemb.MyClass");
Object o = Activator.CreateInstance(type);
MyClass myObj=...

I'm implementing an IDesignerHost, for the CreateComponent method. The code
below is quite standard. When loading a form, the CreateComponent works
fine. However, when someone choose a control from the toolbox, the Activator
couldn't create the component and returns null in CreateInstance. In what
scenario, Activator.CreateInstance will be failed ?? I only create a
System.Windows.Forms.Label. I've verified the type passed in is correct.

this is a repost with more concise code (well, for me) and better questions
(I hope....) .
given the following two classes, my intent is to use either
Activator.CreateInstance or InvokeMember pass a token into the instantiated
class DBPassword and return a string;
**************************************
namespace DBPasswordProvider
public class DBPassword

**************************************
//Load the Assembly
Assembly a = Assembly.LoadFrom(sAssembly);
//Get Types so we can Identify the Interface.
Type mytypes = a.GetTypes();
BindingFlags flags = (BindingFlags.NonPublic | BindingFlags.Public |
BindingFlags.Static | BindingFlags.Instance | BindingFlags.DeclaredOnly);
//Iterate through the Assembly to find Class with a Public Interface.

Hello,
I'm loading a Class from Assemly DLL using Activator.CreateInstance.
That loaded Class is executed in a worker Thread with no loop.
What actually happends when class is loaded using Activator.CreateInstance?
If I create same class using Activator.CreateInstance many times will
there be multiple instances of that same class created by
Activator.CreateInstance?

Okay, that means you've either not given the full classname (including
namespace) or it's not in mscorlib or the currently executing
assembly, in which case you need to give assembly details as well.
The line with testType2 is explicitly trying to find a class called
"name". The string "name" and the variable called name are completely
independent things.

Found it.
string name = Properties.Settings.Default.ClassName.ToString();
//"myproject.myclass, myassembly" format.
//name = "ABC.MyClass, Assem" ;
Type t = Type.GetType(name);
Object obj = Activator.CreateInstance(t);
string result = t.InvokeMember("methodName",

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
