在ASP访问变量的名称。净MVC6

I am trying to access query string parameters in my ASP.NET MVC6 applications. But it seems unlike MVC5 and web forms, QueryString doesn't have any indexer and I can't say something like:

我正在尝试访问我的ASP中的查询字符串参数。净MVC6应用程序。但它似乎不像MVC5和web表单，QueryString没有索引器，我不能说:

string s = Request.QueryString["key1"] //gives error

So, my question is - how do I access query string parameters in MVC6?

我的问题是——如何在MVC6中访问查询字符串参数?

Surprisingly Request.Forms collection works as expected (as in MVC5 or web forms).

令人惊讶的是请求。表单集合按预期工作(如MVC5或web表单)。

Thank you.

谢谢你！

Getting query with an indexer is supported.

支持使用索引器获取查询。

See MVC code test here - https://github.com/aspnet/Mvc/blob/e0b8532735997c439e11fff68dd342d5af59f05f/test/WebSites/ControllersFromServicesClassLibrary/QueryValueService.cs

请参阅下面的MVC代码测试——https://github.com/aspnet/mvc/blob/e0b85327327357c439e11fff68342d5af59f/test/websites/controllersfromservicesclasslibrary/queryvalueservice.cs

context.Request.Query["value"];

Also note that in MVC 6 you can model bind directly from query by using the [FromQuery] attribute.

还要注意，在MVC 6中，您可以使用[FromQuery]属性直接从查询中建模绑定。

public IActionResult ActionMethod([FromQuery]string key1)
{
    ...
}

You can use Request.Query which is new addition in ASPNET 5.

您可以使用请求。查询是在ASPNET 5中新增的。

 var queryStrings = Request.Query;

The URL I am going to try was - http://localhost:12048/Home/Index?p=123&q=456 And you can get All Keys using -

我要尝试的URL是- http://localhost:12048/Home/Index?p=123&q=456，你可以使用-获取所有的键

queryStrings.Keys

And then you can get the values by iterating keys -

然后你可以通过迭代键-来得到值

 var qsList = new List<string>();
 foreach(var key in queryStrings.Keys)
 {
      qsList.Add(queryStrings[key]);
 }
