Question

您的mvc 4应用程序上有一个站点地图，如下所示：

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">
    <mvcSiteMapNode title="Users" controller="User" action="Index" area="" preservedRouteParameters="culture,projectid">
        <mvcSiteMapNode title="New" controller="User" action="Create" area="" preservedRouteParameters="culture,projectid"/>
        <mvcSiteMapNode title="Edit" controller="User" action="Edit" area="" preservedRouteParameters="culture,projectid,id"/>
        <mvcSiteMapNode title="Profile" controller="User" action="Details" area="" preservedRouteParameters="culture,projectid,id"/>            
    </mvcSiteMapNode>
</mvcSiteMap>

我在另一个用于全球化我的应用程序的项目中有很少的资源文件，我需要在一个单独的项目中使用资源文件，因为它在ddl等少数项目中使用。

如何为我的站点地图实施全球化？

Answer 1

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"/>

或者

[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
