c# - Activator.CreateInstance, : Constructor on type 'Pastel.Evolution.PurchaseOrder' not found -

-

i have gotten point trying create instance of class in assembly have loaded.

 object obj= activator.createinstance(purchaseorder,                                         bindingflags.nonpublic |                                         bindingflags.instance,                                         null, new object[] { purchaseorderdocumentbase }, null);

i keep getting error :

an unhandled exception of type 'system.missingmethodexception' occurred in mscorlib.dll additional information: constructor on type 'pastel.evolution.purchaseorder' not found.

what read already:

most of people referring constructors being private. type loading has 4 constructors public. refer type not having default constructor, thing problem.

i have tried invoke first constructor has no parameters : 

constractor.invoke(purchaseorder, null);

i following error.

an unhandled exception of type 'system.reflection.targetexception' occurred in mscorlib.dll additional information: object not match target type.

can shed light on please.

thank in advance.
