ASP.NET MVC 3, how should I assign <form> attributes with HtmlHelper.BeginForm?

Question

I want to assign HTML attributes to forms created with Html.BeginForm in ASP.NET MVC 3 views, but it seems I have to use the overload

BeginForm(this HtmlHelper htmlHelper, 
          string actionName, 
          string controllerName, 
          FormMethod method, 
          Object htmlAttributes
)

invoking it like this:

Html.BeginForm(null, null, FormMethod.Post, new {id = "my-form"})

Is there some easier way to do this, so I can pass e.g. new {id = "my-form"} as the only argument to Html.BeginForm?

No, there isn't unless you write your own HTML helper:

public static class FormExtensions
{
    public static MvcForm MyBeginForm(this HtmlHelper htmlHelper, object htmlAttributes)
    {
        return htmlHelper.BeginForm(null, null, FormMethod.Post, htmlAttributes);
    }
}

and then:

@using (Html.MyBeginForm(new { id = "my-form" }))
{
    ...
}

Unfortunately you cannot use BeginForm as name because there is already an overload with the same signature in which the parameter represents routeValues though.

Write your own extension method.

public static class MyFormExtensions { 
  public static MvcForm BeginForm(this HtmlHelper htmlHelper, Object htmlAttributes)
  {
     return htmlHelper.BeginForm(null, null, FormMethod.Post, htmlAttributes);
  }
}

How do you intend to invoke this custom helper on the view?
