Sure can:
using System;
namespace ReflectTest
{
public abstract class Test
{
public static Test CreateTest(string type)
{
return((Test)typeof(Test).Assembly.CreateInstance(type,true));
}
}
public class TestA : Test
{
}
public class TestB : Test
{
}
public class DoTestCreation
{
public static void Run()
{
object o = Test.CreateTest("ReflectTest.TestA");
if(o != null)
{
System.Windows.Forms.MessageBox.Show(o.GetType().Name);
}
o = Test.CreateTest("ReflectTest.TestB");
if(o != null)
{
System.Windows.Forms.MessageBox.Show(o.GetType().Name);
}
}
}
}

Subject: [ADVANCED-DOTNET] Using reflection internally to create an
instance based on a string name
Can reflection be used internally to create a class instance based on an
input string containing the class name? Something somewhat similar to
the
code below however typeof takes a type as an argument, not a string.
Activator.CreateInstance seems to require that a reference to the
containing .dll is obtained. I'm interested in creating an instance of a
class defined in the same assembly as the creator method based on an
input
string that matches the class name.
// Some dll
public abstract class InstanceCreator
{
public static InstanceCreator GetObject(string type)
{
return typeof(type); // return type with name corresponding to
input string
}
}
public class SomeClass1
{
}
public class SomeClass2
{
}
// end some dll
