Using System.Activator.CreateInstance you can create instances of a class using reflection. For example...

System.Type type = typeof(Sample);
object obj = Activator.CreateInstance(type);

In this example obj is your newly created instance. There's few overloads of this method, more information in this MSDN Documentation

Edit Based On Comment

If what you want is to be able to retrieve all instances of a class, I guess this is not possible using managed code. You will need to use unmanaged code to either profile the managed heap using the Profiling API or use the HeapWalk function to enumerating all objects allocated in the managed heap.

var s = (Sample)Activator.CreateInstance(Sample);
var s2 = (Sample)Activator.CreateInstance(Sample);
var s3 = (Sample)Activator.CreateInstance(Sample);
