You can use Request.UrlReferrer to get the referring URL as well if you don't like accessing the Request.ServerVariables dictionary directly.

您可以使用请求。如果不喜欢访问请求，也可以使用UrlReferrer来获取引用URL。直接ServerVariables字典。

{
    var str = htmlHelper.HiddenFor(_ => _.Referrer);
    var referrer = HttpContext.Current.Request.UrlReferrer.AbsoluteUri;
    return new MvcHtmlString(str.ToHtmlString().Replace("value=\"\"", String.Format("value=\"{0}\"", referrer)));
}
