    I am trying to find all the check box that are checked on a html form in an page using LINQ query and I am having some problem. I am not sure what I am doing wrong.

IEnumerable<string>  cbChecked = Request.Form.Cast<string>().Where(c => c.Contains("cb_"));

I checked the form and it contains all the check boxes check.

Have you tried:
var cbChecked = Request.Form.OfType<CheckBox>().Select(c => c.Checked);

Correct solution was
IEnumerable  cbChecked = Request.Form.OfType().Where(c => c.Contains("cb_"));
