Note   An operating-system ThreadId has no fixed relationship to a managed thread, because an unmanaged host can control the relationship between managed and unmanaged threads. Specifically, a sophisticated host can use the fiber API to schedule many managed threads against the same operating system thread, or to move a managed thread between different operating system threads.<br />

Type t = myDynamicallyLoadedObj.GetType();
MethodInfo m = t.GetMethod("Swap");

args = new object[2];
args[0] = 1;
args[1] = 2;

m.Invoke(myDynalicallyLoadedObj,args);

public void Swap(ref int a, ref int b)
{
  int x = a;
  a = b;
  b = x;
}
