How to code a C# Extension method to turn a Domain Model object into an Interface object?
- by Dr. Zim
When you have a domain object that needs to display as an interface control, like a drop down list, ifwdev suggested creating an extension method to add a .ToSelectList().
The originating object is a List of objects that have properties identical to the .Text and .Value properties of the drop down list. Basically, it's a List of SelectList objects, just not of the same class name.
I imagine you could use reflection to turn the domain object into an interface object. Anyone have any suggestions for C# code that could do this? The SelectList is an MVC drop down list of SelectListItem.
The idea of course is to do something like this in the view:
<%= Html.DropDownList("City",
(IEnumerable<SelectListItem>) ViewData["Cities"].ToSelectList() )
