Here are some snippets of code that we use to assign members to a project, hopefully this helps you out!

In the view we have:

<p>
    <label>
       Select project members:</label>
    <ul>
        <% foreach (var user in this.Model.Users)
           { %>
        <li>
            <%= this.Html.CheckBox("Member" + user.UserId, this.Model.Project.IsUserInMembers(user.UserId)) %><label
                for="Member<%= user.UserId %>" class="inline"><%= user.Name%></label></li>
        <% } %></ul>
</p>

In the controller we have:

// update project members   
foreach (var key in collection.Keys)    
{   
    if (key.ToString().StartsWith("Member"))
    {
        int userId = int.Parse(key.ToString().Replace("Member", ""));   
        if (collection[key.ToString()].Contains("true"))    
            this.ProjectRepository.AddMemberToProject(id, userId);
        else
                        this.ProjectRepository.DeleteMemberFromProject(id, userId);
    }
}

The main thing to remember when working with the Html Checkbox Helper is to use contains() to determine true or false.
