静态类System.Configuration.ConfigurationManager的别名;(Alias to static class System.Configuration.Configur

静态类System.Configuration.ConfigurationManager的别名;(Alias to static class System.Configuration.ConfigurationManager;)

我想声明一个静态类的别名： System.Configuration.ConfigurationManager;

我希望这个别名可用于我班级的所有方法，所以我试图这样做：

public class MyClass { using conf = System.Configuration.ConfigurationManager; public void MethodOne() { string appConfigStr = conf.AppSettings["someAppSettings"].ToString() } }

但上面引发了以下错误 ：类，结构或接口成员声明中的令牌“使用”无效

我可以做些什么来为这个配置管理器类别名吗？

I would like to declare an alias to the static class : System.Configuration.ConfigurationManager;

I would like this alias to be available to all the methods of my class so I've tried to do that :

public class MyClass { using conf = System.Configuration.ConfigurationManager; public void MethodOne() { string appConfigStr = conf.AppSettings["someAppSettings"].ToString() } }

But the above raises the following error : Invalid token 'using' in class, struct, or interface member declaration

Is there something I can do to alias this configuration manager class ?

最满意答案

using指令可用于在当前.cs文件的范围内创建别名。

using conf = System.Configuration.ConfigurationManager; namespace MyNamespace { public class MyClass { public void MethodOne() { string appConfigStr = conf.AppSettings["someAppSettings"].ToString() } } }

有关更多信息，请参阅此文档

using directives can be used to create an alias within the scope of the current .cs file.

using conf = System.Configuration.ConfigurationManager; namespace MyNamespace { public class MyClass { public void MethodOne() { string appConfigStr = conf.AppSettings["someAppSettings"].ToString() } } }
