怎样的Request.QueryString传递给Url.Action？ [英] How to pass Request.QueryString to Url.Action?

问题描述

我使用的方法建立一个网址：

I'm building an url using the method:

Url.Action("action", "controller");

我想通过查询字符串当前请求到该网址为好。
类似如下（但它不工作）：

I like to pass the querystring for the current request into that url as well. Something like the following (but it doesn't work):

Url.Action("action", "controller", Request.QueryString);

查询字符串转换为routevalues​​可能有以下扩展名：

Converting the QueryString to routevalues is possible with the following extension:

    public static RouteValueDictionary ToRouteValues(this NameValueCollection queryString)
    {
        if (queryString.IsNull() || queryString.HasKeys() == false) return new RouteValueDictionary();

        var routeValues = new RouteValueDictionary();
        foreach (string key in queryString.AllKeys)
            routeValues.Add(key, queryString[key]);

        return routeValues;
    }

通过扩展方式下不工作：

With the extension method the following does work:

Url.Action("action", "controller", Request.QueryString.ToRouteValues());

是否有其他更好的办法？

Is there an other better way ? Thx
