创建一些东西@using(Html.BeginForm())助手

Question

在Asp.net MVC3中,当您编写下面的代码时,它会自动生成包装html

 @using (Html.BeginForm()) {
                @Html.ValidationMessageFor(model => model.Text)
}

它生成以下格式的代码,

<form method="post" action="/Feeds">
   <!-- Fields Here -->
</form>

我的问题在 开始和结束时@using (Html.BeginForm())自动添加<form>标签,我怎样才能创建类似我自己的标签.

我正在寻找下面的东西

@using (Html.BeginMYCUSTOMDIV())
  {
        I am text inside div
  }

预期的生成输出

<div class="customDivClass">
I am text inside div
</div>

一些事情:

public class MyDiv : IDisposable
{
    private readonly TextWriter _writer;
    public MyDiv(TextWriter writer)
    {
        _writer = writer;
    }

    public void Dispose()
    {
        _writer.WriteLine("</div>");
    }
}

public static class MyExtensions
{
    public static MyDiv BeginMYCUSTOMDIV(this HtmlHelper htmlHelper)
    {
        var div = new TagBuilder("div");
        div.AddCssClass("customDivClass");
        htmlHelper.ViewContext.Writer.WriteLine(div.ToString(TagRenderMode.StartTag));
        return new MyDiv(htmlHelper.ViewContext.Writer);
    }
}

并在视图中:

@using (Html.BeginMYCUSTOMDIV())
{
    <span>Hello</span>
}

产生:

<div class="customDivClass">
    <span>Hello</span>
</div>
