如何在ASP.NET 5 MVC6中的布局文件中获取会话值 [英] How to get a session value in layout file in ASP.NET 5 MVC6

问题描述

在ASP.NET 5 MVC 6 Beta 8中，我需要在_Layout.cshtml中读取会话变量，或者获取对当前HttpContext的引用.

In ASP.NET 5 MVC 6 Beta 8 I need to read a session variable in in my _Layout.cshtml or alternatively get a reference to the current HttpContext.

请注意:在ASP.NET 5中，与

Take note: In ASP.NET 5 referencing the Session object has changed significantly from ASP.net 4 as detailed in this question

Context对象在Beta7和Beta8之间也已重命名为HttpContext.

The Context object has also been renamed to HttpContext between Beta7 and Beta8.

在我当前的控制器中，我目前这样保存会话变量

In My current controller I currently save the session variable like this

public IActionResult Index()
{
    HttpContext.Session.SetInt32("Template", (id));
}

在我的_Layout.cshtml中，我需要阅读上述会话变量. 我需要以某种方式引用当前的HttpContext，例如

In my _Layout.cshtml I need to read the above session variable. I need to reference the current HttpContext somehow e.g

HttpContext.Current.Session.GetInt32("Template");

但是我不知道如何在cshtml文件中获取当前的HttpContext.

but I don't know how to the get the current HttpContext in a cshtml file.

推荐答案

Context和HttpContext之间的命名有些混乱.您可以使用Context属性在视图中访问HttpContext:

The naming between Context and HttpContext is somewhat confusing. You can access the HttpContext in a view using the Context property:

@{ int x = Context.Session.GetInt32("test"); }

MVC存储库中还有一个与此相关的待解决问题: https://github.com/aspnet/Mvc/Issues/3332

There is also a pending issue at the MVC repo regarding this: https://github.com/aspnet/Mvc/issues/3332
