@Html.TextBoxFor(m => m.Name, new {Value = Html.DisplayNameFor(m => m.Name)})

EDIT: If you need to re-display the form and preserve the value that the user entered, then you might want to either use Darin's approach, or do something like this:

@Html.TextBoxFor(m => m.Name, new { Value = (string.IsNullOrWhiteSpace(Model.Name) ? Html.DisplayNameFor(x => x.Name).ToHtmlString() : Model.Name) })

In the controller action rendering this view you could set the Name property of your view model:

public ActionResult Index()
{
    var model = new MyViewModel();
    model.Name = ModelMetadata.FromLambdaExpression<MyViewModel, string>(x => x.Name, new ViewDataDictionary<MyViewModel>(model)).DisplayName;
    return View(model);
}

and in your view:

@Html.LabelFor(x => x.Name)
@Html.EditorFor(x => x.Name)
