当前上下文中不存在名称“数据库"? [英] The name 'Database' does not exist in the current context?
问题描述
当我尝试使用 WebMatrix 启动我的网站时出现此错误.我有一个 .cs 文件,它调用 var db = Database.Open("dbase");
.
I am getting this error when I try to launch my website using WebMatrix. I have a .cs file which makes a call var db = Database.Open("dbase");
.
我的项目中有一个名为dbase"的数据库.我没有 web.config 文件,也没有使用 WebMatrix 包的导入,因为我使用 WebMatrix 启动站点,所以我认为我不需要它们.我是否需要将代码包装在 Razor 标签中,例如 @{var db = Database.Open("dbase");}
?这也给我带来了错误.
I have a database in my project called "dbase". I have no web.config file and no imports for using WebMatrix packages since I am launching the site using WebMatrix, so I don't believe I should need them. Do I need to wrap the code in Razor tags, like @{var db = Database.Open("dbase"); }
? This causes an error for me too.
可能是什么原因造成的?有没有人对此有任何解决方案?
What could be causing this? Does anyone have any solutions for this?
推荐答案
您需要对 WebMatrix.Data.dll
程序集(您可能拥有)的引用,并且您还em> 需要一个用于 WebMatrix.Data
命名空间的 using
指令:
You need a reference to the WebMatrix.Data.dll
assembly (which you probably have) and you also need a using
directive for the WebMatrix.Data
namespace:
using WebMatrix.Data;
这将导入数据库
类,因此您无需完全限定名称即可使用它.
That will import the Database
class so you can use it without fully-qualifying the name.
不清楚为什么你认为你不需要任何导入"(我假设你的意思是使用上面的指令)但是如果这是在一个普通的 C# 文件中,那么你当然 do 需要它们(或者您需要完全限定类型名称,这很丑陋).
It's not clear why you think you wouldn't need any "imports" (by which I assume you mean using directives like the one above) but if this is in a plain C# file, then you certainly do need them (or you need to fully-qualify type names, which is ugly).
