在asp.net mvc的设置查询字符串redirecttoaction [英] setting query string in redirecttoaction in asp.net mvc

问题描述

我必须做在asp.net mvc的视图 redirecttoaction 调用具有不同参数，可以从视图（网格的状态）的引用页提取。

我（在隐藏字段）查询字符串的内容（有时是空的，有时2个参数等），所以我有问题，创建路由值数组。

是否有一些助手，这帮助我转换查询字符串路由值数组？
是这样的：

 字符串查询字符串=sortdir = ASC＆放大器; PAG = 5;
返回RedirectToAction（指数，ConvertToRouteArray（查询字符串））;
 

解决方案

要创建一个通用的解决方案您的查询字符串转换为字典和词典的RouteValueDictionary。

  VAR分析= HttpUtility.ParseQueryString（TEMP）;
字典＆LT;字符串对象＆gt; querystringDic = parsed.AllKeys
    .ToDictionary（K =＆GT; K，K =＆GT;（对象）解析[K]）;返回RedirectToAction（指数，新RouteValueDictionary（querystringDic））;
 

I have to do a redirecttoaction call in asp.net mvc view with varying params, extracted from the referrer page of the view (the status of a grid).

I have (in an hidden field) the content of the query string (sometimes empty, sometimes with 2 parameters and so on), so I have problems to create the route values array.

Are there some helpers, that help me to convert a query string a route values array? Something like:

string querystring ="sortdir=asc&pag=5";
return RedirectToAction( "Index", ConvertToRouteArray(querystring));

解决方案

To create a generic solution convert your querystring to a Dictionary and at the dictionary to the RouteValueDictionary.

var parsed = HttpUtility.ParseQueryString(temp); 
Dictionary<string,object> querystringDic = parsed.AllKeys
    .ToDictionary(k => k, k => (object)parsed[k]); 

return RedirectToAction("Index", new RouteValueDictionary(querystringDic));
