MVC在网页中引用js脚本，下面两种格式的效果是一样的吗？一样的有什么区别？

[whoamiwho]

    <script src="@Url.Content("~/script/jquery.js")"></script>  
   <script src="~/script/jquery.js"></script>

看到一些项目用的是第一个，但是第二个好像也可以，有区别吗

MVC4/Razor2.0 里面用第二种就好了 微软的东西有时候就这样让人很蛋疼 新瓶装旧酒

        public string Content(string contentPath) {
            return Content(contentPath, RequestContext.HttpContext);
        }

        internal static string Content(string contentPath, HttpContextBase httpContext) {
            if (String.IsNullOrEmpty(contentPath)) {
                throw new ArgumentException(MvcResources.Common_NullOrEmpty, "contentPath");
            }

            if (contentPath[0] == '~') {
                return PathHelpers.GenerateClientUrl(httpContext, contentPath);
            }
            else {
                return contentPath;
            }
        }

            // base it from / instead of /foo, otherwise the user ends up seeing mysite.example.com/foo/bar,
            // which is incorrect.

要是网站放在虚拟目录下可能会有问题

[zhang_zhen1234]

第一种没问题，但是没有智能提示 哎

第二种使用的虚拟路径，会有什么问题呢？
