c# - Object of type 'System.Reflection.MdFieldInfo' cannot be converted to type 'MyEnum' -

-

i loading assembly @ runtime , trying lot of operations @ runtime going far anyways trying achieve:

i have class called student in foreign assembly loading @ runtime

public class student {     public bool isgood { get; set; }     public studenttype st { get; set; }     public university university { get; set; } }

i can dynamically load object assembly doing like:

var assembly = assembly.loadfrom("//path");  type type = assembly.gettype("testframework.student"); var student = activator.createinstance(type);

now, comes turn set properties type dynamically loaded foreign assembly. 

type universitytype = assembly.gettype("testframework.university"); type.getproperty("university").setvalue(student, activator.createinstance(universitytype), null);

nice part works too!!

but

here problem starts. when try assign studenttype enum same assembly fails error

object of type 'system.reflection.mdfieldinfo' cannot converted to

type 'myenum'

this how trying set it:

type3 = assembly.gettype("testframework.studenttype"); type.getproperty("st").setvalue(student, type3.getfield("good"), null);

this code fails..

i think need field.getvalue here

type.getproperty("st").setvalue(student, type3.getfield("good").getvalue(instance), null);

type.getfield returns fieldinfo need pass parameter enum value.

note: assume good field on type3 of type enum studenttype
