                 }
           }     
      }  
 }

My problem is that i can use Activator.Createinstance against mystuff and that works great but how do i set the parameters in ParmBlock? everything ive tried so far has failed and im slowly going nuts here.....

thanks

Use the PropertyInfo you get via a call to the GetProperty() call on the type itself. Then you can use the PropertyInfo.GetValue() and PropertyInfo.SetValue Methods.

void example( Object target, string propertyName )
{
    PropertyInfo info = typeof(target).GetProperty( propertyName );

    object value = info.GetValue( target, new object[] {} );
}
