Activator Createinstance Type Gettype
You re only specifying the FullName of the Type, which is ironically not the full name you need. Type.GetType string requires the AssemblyQualifiedName of the Type in order to work:
Type.GetType new my.namespace.item. GetType. AssemblyQualifiedName
should be fine. Specifying it manually would look like:
Type.GetType Namespace.TypeName, MyAssemblyName, Version 1.0.0.0, Culture neutral, PublicKeyToken b17a5c561934e089 ;
Obviously you can omit the Version, Culture, or PublicKeyToken if they don t apply.

The following code example demonstrates how to call the CreateInstance Type method. Instances of several different types are created and their default values are displayed.
private static string instanceSpec System.EventArgs;System.Random;
System.Exception;System.Object;System.Version ;
string instances instanceSpec.Split ; ;
Array instlist Array.CreateInstance typeof object, instances.Length ;
for int i 0; i instances.Length; i
// create the object from the specification string
Console.WriteLine Creating instance of: 0, instances i ;
item Activator.CreateInstance Type.GetType instances i ;
Console.WriteLine nObjects and their default values: n ;
Console.WriteLine Type: 0 nValue: 1 nHashCode: 2 n,
o.GetType. FullName, o.ToString, o.GetHashCode ;
// This program will display output similar to the following:
// Creating instance of: System.EventArgs
// Creating instance of: System.Random
// Creating instance of: System.Exception
// Creating instance of: System.Object
// Creating instance of: System.Version
// Objects and their default values:
// Value: System.Exception: Exception of type System.Exception was thrown.
