Get multiple checked CheckBoxes values in ASP.Net MVC

I used inside the foreach condition where statement so i cannot able to take checked value count. so how can i get the checked value count?

<ul id="tree" class="dd-list">
    @foreach (var domain in Model.DomainViews)
    {
        <li class="dd-item">
            <a>
                @Html.CheckBoxFor(model => domain.IsChecked, new { @id = domain.DomainID, name = "DomainViews" })
                <label for="@domain.DomainID">@domain.DomainName</label>
                @Html.HiddenFor(model => domain.DomainID, new { id = "hdnDomainID" })
            </a>
            <ul class="dd-list">
                @foreach (var module in @Model.ModuleViews.Where(x => x.DomainID == domain.DomainID))
                {
                    <li class="dd-item">
                        <a>
                            @Html.CheckBoxFor(model => module.IsChecked, new { @id = module.ModuleID, name = "ModuleViews" })
                            <label for="@module.ModuleID"> @module.ModuleName</label>
                        </a>
                        <ul class="dd-list">
                            @foreach (var child in @Model.ChildModuleViews.Where(x => x.ParentModuleID == module.ModuleID))
                            {
                                <li class="dd-item">
                                    <a>
                                        @Html.CheckBoxFor(model => child.IsChecked, new { @id = child.ModuleID, name = "ChildModuleViews" })
                                        <label for="@child.ModuleID"> @child.ModuleName</label>
                                    </a>
                                </li>
                            }
                        </ul>
                    </li>
                }
            </ul>
        </li>
    }
</ul>

I know to take count from for loop statement. but i don't know how use where condition in for statement.
