MVC站点地​​图提供程序和本地化

我今天发现,对于我的网站,我可以使用我从Github下载MVC3的SiteMap提供程序,因为我的Web应用程序是MVC3。

情况如下,我的申请是多语言的。我有一个单独的库,其中包含所有资源。然后将此库添加到我当前的项目以及我需要使用这些资源文件的任何地方。

现在我已经实现了站点地图提供程序:

  <mvcSiteMapNode title="$resources:Base,Home" controller="Home" action="Index" enableLocalization="true">
    <mvcSiteMapNode title="Search" controller="Search" action="Index"/>
    <mvcSiteMapNode title="Contact" controller="Contact" action="Index"/>
    <mvcSiteMapNode title="About" controller="Home" action="About"/>
  </mvcSiteMapNode>

但是当我运行它时,我得到一个错误,因为它无法找到关键主页的资源。我认为这是因为它不在应用程序之外,而是在一个单独的库中。

我如何指向资源文件,这是位于单独的项目?

我将采用的方法是切换到外部DI,然后实现一个可以从另一个程序集中读取资源的自定义IStringLocalizer类。这是一个有效的例子。我也在GitHub上创建了一个demo application

using System;
using System.Collections.Specialized;
using System.Resources;

namespace MvcSiteMapProvider.Globalization
{
    public class ResourceManagerStringLocalizer
        : IStringLocalizer
    {
        public ResourceManagerStringLocalizer(
            ResourceManager resourceManager
            )
        {
            if (resourceManager == null)
                throw new ArgumentNullException("resourceManager");
            this.resourceManager = resourceManager;
        }
        protected readonly ResourceManager resourceManager;

        /// <summary>
        /// Gets the localized text for the supplied attributeName.
        /// </summary>
        /// <param name="attributeName">The name of the attribute (as if it were in the original XML file).</param>
        /// <param name="value">The current object's value of the attribute.</param>
        /// <param name="enableLocalization">True if localization has been enabled, otherwise false.</param>
        /// <param name="classKey">The resource key from the ISiteMap class.</param>
        /// <param name="implicitResourceKey">The implicit resource key.</param>
        /// <param name="explicitResourceKeys">A <see cref="T:System.Collections.Specialized.NameValueCollection"/> containing the explicit resource keys.</param>
        /// <returns></returns>
        public virtual string GetResourceString(string attributeName, string value, bool enableLocalization, string classKey, string implicitResourceKey, NameValueCollection explicitResourceKeys)
        {
            if (attributeName == null)
            {
                throw new ArgumentNullException("attributeName");
            }

            if (enableLocalization)
            {
                string result = string.Empty;
                if (explicitResourceKeys != null)
                {
                    string[] values = explicitResourceKeys.GetValues(attributeName);
                    if ((values == null) || (values.Length <= 1))
                    {
                        result = value;
                    }
                    else if (this.resourceManager.BaseName.Equals(values[0]))
                    {
                        try
                        {
                            result = this.resourceManager.GetString(values[1]);
                        }
                        catch (MissingManifestResourceException)
                        {
                            if (!string.IsNullOrEmpty(value))
                            {
                                result = value;
                            }
                        }
                    }
                }
                if (!string.IsNullOrEmpty(result))
                {
                    return result;
                }
            }
            if (!string.IsNullOrEmpty(value))
            {
                return value;
            }

            return string.Empty;
        }
    }
}

然后你可以将它注入你的DI配置模块(显示的StructureMap示例,但任何DI容器都可以)。

首先,您需要指定不通过将其添加到excludeTypes变量来自动注册IStringLocalizer接口。

var excludeTypes = new Type[] {
// Use this array to add types you wish to explicitly exclude from convention-based  
// auto-registration. By default all types that either match I[TypeName] = [TypeName] or 
// I[TypeName] = [TypeName]Adapter will be automatically wired up as long as they don't 
// have the [ExcludeFromAutoRegistrationAttribute].
//
// If you want to override a type that follows the convention, you should add the name 
// of either the implementation name or the interface that it inherits to this list and 
// add your manual registration code below. This will prevent duplicate registrations 
// of the types from occurring. 

// Example:
// typeof(SiteMap),
// typeof(SiteMapNodeVisibilityProviderStrategy)
    typeof(IStringLocalizer)
};

然后提供ResourceManagerStringLocalizer(及其依赖项)的显式注册。

// Configure localization

// Fully qualified namespace.resourcefile (.resx) name without the extension
string resourceBaseName = "SomeAssembly.Resources.Resource1";

// A reference to the assembly where your resources reside.
Assembly resourceAssembly = typeof(SomeAssembly.Class1).Assembly;

// Register the ResourceManager (note that this is application wide - if you are 
// using ResourceManager in your DI setup already you may need to use a named 
// instance or SmartInstance to specify a specific object to inject)
this.For<ResourceManager>().Use(() => new ResourceManager(resourceBaseName, resourceAssembly));

// Register the ResourceManagerStringLocalizer (uses the ResourceManger)
this.For<IStringLocalizer>().Use<ResourceManagerStringLocalizer>();

然后,只需要适当地指定资源即可。您需要使用Base Name(在本例中为SomeAssembly.Resources.Resource1)启动它们,然后将资源的键指定为第二个参数。

<mvcSiteMapNode title="$resources:SomeAssembly.Resources.Resource1,ContactTitle" controller="Home" action="Contact"/>

请注意,正确获取BaseName是使其工作的关键。请参阅以下MSDN文档:http://msdn.microsoft.com/en-us/library/yfsz7ac5(v=vs.110).aspx

我认为应该是这样的:

假设你:

<强>项目名= MyProject的

文件夹,其中包含资源:LanguageFiles

资源

然后

应该是这样的我相信......我不确定,但它可能适合你:

`title=@MyProject.LanguageFiles.Messaging.Home'

(假设Home是Messaging类中定义的资源)
