How do you access application variables in asp.net mvc 3 razor views?
能否使用 asp.net mvc2.0 访问控制器中的控制器应用变量
例如,在全球.asax中:
Application["AppVar"] = "hello";
在任何控制器方法中:
string appVar = HttpContext.Application["AppVar"] as string;
Update (7/2018):
If you need to access MVC global application data from a DLL library:
using System.Web;
....
if (HttpContext.Current != null && HttpContext.Current.Application != null)
string appVar = HttpContext.Current.Application["AppVar"] as string;
检查 HttpContext 比较安全。 目前, 申请反对无效也比较安全, 因为一些伪造的 httpcontext 库( 用于单位测试项目) 可能有无效的“ 申请” 有效上下文 。
