我需要<div>使用’forumChild’类更改标签的CSS 类。它必须每隔foreach循环的3个循环进行一次更改。

有没有一种方法可以从控件内部执行此操作？

<div class="Forum">
    <p>The Forum</p>

            @foreach (var item in Model)
            {               
                <div class="ForumChild">

                    <img src="@item.Blog.Image.img_path" alt="Not Found" />

                    <br />
                            @foreach (var comment in item.Blog.comment)
                            {

                                var db = new ACapture.Models.ACaptureDB();

                                var Name = from p in db.Profile.AsEnumerable()
                                           where (p.AccountID == comment.AccountID)
                                           select p;                            
                            <section>
                                    <div>
                                        <a href="@Url.Action("Index", "Home")">@foreach (var y in Name)
                                                                              { @(y.FirstName + " " + y.LastName + ":");
                                                                              }</a>
                                    </div>
                                    <div>
                                        @comment.Commentation 
                                    </div>
                            </section>
                            }
                </div>                
            }
</div>
