How to Access the CheckBox Value in ASP.NET MVC without using method parameter

Question

I use the following HTML helper to generate check box:

<%= Html.CheckBox("DeluxeFeature")%>

Now I want to access the value of this checkbox in my controller. How should I do this? I am not going to use the method parameter name, for the reason that there are a lot of checkboxes and putting all of them in the parameter will clutter the method.

I try to use

Request.Form["DeluxeFeature"]

But the behavior is very weird; if the checkbox is not ticked, then the Request.Form["DeluxeFeature"] returns "false", which is expected. But if the checkbox is ticked, then it retruns "true, false".

Very weird, isn't it?

is there something else in your form named "DeluxeFeature"?

This thread on the asp.net forums explains the behavior - there's even a comment by Phil Haack from the ASP.NET MVC project team (bonus!!).

So the best way to handle it if you're not using the helpers/model binders as posted by levib seems to be

Request.Form.GetValues("DeluxeFeature")[0]

This worked for me.

var checkbox = Request.Form.Get("DeluxeFeature");
if (checkbox.Contains("true"))
{
    //Whatever code if the checkbox is checked.
}
