Here is your problem, the Invoke method overload you're using takes the
target object and an array or arguments. In your case you only have one
argument which is a object array.

Change:
object temp = myType.GetMethod("Exec").Invoke(myInstance, obj);

To:
object temp = myType.GetMethod("Exec").Invoke(myInstance,new object[]{
obj});
