"""http://t4mvc.codeplex.com/" rel="nofollow" >T4MVC 的好东西是,它允许你摆脱literal/magic tring 。

T4MVC is a T4 template f或 ASP.NET MVC apps that creates strongly typed helpers that eliminate the use of literal strings when referring the controllers, actions and views.

在 Web.config 文件内的应用程序设置中,是否可以有类似的设置:

<appSettings>
    <add key="SecurityGuardEmailFrom" value="[email protected]" />
    <add key="Passw或dExpiresInDays" value="1" />
    <add key="NumberOfPassw或dsToKeep" value="5" />
</appSettings>

所以,而不是这个:

private static readonly int Passw或dExpiresInDays =
int.Parse(ConfigurationManager.AppSettings["Passw或dExpiresInDays"]);

我们有这样的东西:

MVC.Webconfig.Passw或dExpiresInDays

或

MVC.AppSettings.Passw或dExpiresInDays

This would help in compile time to check if the app setting is still there avoiding runtime err或s.

这是否可行?如果可行,你是否知道在某处是否已经实施了类似的做法?

有趣的是, 在我用不同的字眼张贴了这个问题后, 我谷歌上用不同的字眼搜索, 找到了一些东西: T4 模板, 处理内置时有不错的错误... 这里的文章是:

"http://www.wynia.org/wewpress/2010/04/t4-template-for-applates-appings-access-in-config-files" rel=“nofollow”>T4 AppsSettings Access in Config 文件

我不得不更改文章中提供的T, 以便在我当前的环境中运作(VS 11 Beta + ASP.NET MVC 4 App)。

这些是Im使用的进口品:

<#@ template language="C#" debug="true" hostspecific="true" #>
<#@ output extension=".cs" #>
<#@ Assembly Name="System.Core.dll" #>
<#@ assembly name="EnvDTE" #>
<#@ Assembly name="System.Configuration"#>
<#@ import namespace="System" #>

<#@ import namespace="System.Collections" #>
<#@ import namespace="System.Collections.Specialized"#>
<#@ import namespace="System.Collections.Generic" #>
<#@ import namespace="System.Configuration" #>

Web.config 中的一些应用程序设置在它们的名称中有一个冒号( : ), 例如 < code> webpages: Version 。这就是我使它发挥作用的手法 :

public static string  <#=setting.Replace(":", "")#>
{
    get
    {
        return getConfigSetting("<#=setting#>");
    }
}

注意 < code> section. replace 上面的 < code> replace 。

如果您愿意的话, 您也可以调试 T4 模板。请遵循这里描述的步骤 :

创建自定义配置区域, 而不是在中设置设置。

You can extend ASP.NET configuration settings with XML configuration elements of your own. To do this, you create a custom configuration section handler. The handler must be a .NET Framework class that inherits from the System.Configuration.ConfigurationSection class. The section handler interprets and processes the settings that are defined in XML configuration elements in a specific section of a Web.config file. You can read and write these settings through the handler s properties.
