MVC Binding to checkbox

Question

I have found so many questions about this, but none of them go over or seem to go over my scenario. I have a model:

public class CheckBoxModel
{

An alternative to Darin's fantastic answer

I definitely recommend following Darin's approach for returning classes which will be most of the time. This alternative is a 'quick' and dirty hack if all you need is the checked Ids:

<% foreach (var cb in Model.CheckBoxes) { %>
  

    
      name="ids" />
  
<% } %>

Will bind to the int[] ids parameter in the following action:

[HttpPost]
public ActionResult MyAction(int[] ids) 
{
    // ids contains only those ids that were selected
    ...
}

• The benefit is cleaner html as there is no hidden input.
• The cost is writing more code in the view.

In MVC 4.0 (Razor 2.0) you can use the following syntax in your view:
