原以为可以使用之前的多国语言方案进行编程了，没想到第一个正式点的页面就卡了，为什么呢，因为通过HtmlHelper只能找到当前请求的
View是哪个，如果这个View使用了Layout或是Partial就歇菜了。通过一番尝试，发现使用
HtmlHelper.ViewDataContainer属性可以获得一个WebViewPage对象，这个对象中的VirtualPath对象代表当
前正在Excute的页面属于哪个物理文件(.cshtml)，于是修改代码如下:
public static class LocalizationHelper |
public static string Lang(this HtmlHelper htmlhelper, string key) |
var viewPath = (htmlhelper.ViewDataContainer as WebViewPage).VirtualPath; |
var viewName = viewPath.Substring(viewPath.LastIndexOf('/'), viewPath.Length - viewPath.LastIndexOf('/')).TrimStart('/'); |
var filePath = htmlhelper.ViewContext.HttpContext.Server.MapPath(viewPath.Substring(0, viewPath.LastIndexOf('/') + 1)) + "App_LocalResources"; |
var langs = htmlhelper.ViewContext.HttpContext.Request.UserLanguages.Union<string>(new string[] { "" }); |
IEnumerable<DictionaryEntry> resxs = null; |
foreach (var lang in langs) |
string.IsNullOrWhiteSpace(lang) ? string.Format(@"{0}\{1}.resx", filePath, viewName) : string.Format(@"{0}\{1}.{2}.resx", filePath, viewName, lang); |
resxs = GetResx(resxKey); |
if (resxs != null) { break; } |
return (string)resxs.FirstOrDefault<DictionaryEntry>(x => x.Key.ToString() == key).Value; |
private static IEnumerable<DictionaryEntry> GetResx(string resxKey) |
ObjectCache cache = MemoryCache.Default; |
IEnumerable<DictionaryEntry> resxs = null; |
if (cache.Contains(resxKey)) |
resxs = cache.GetCacheItem(resxKey).Value as IEnumerable<DictionaryEntry>; |
if (File.Exists(resxKey)) |
resxs = new ResXResourceReader(resxKey).Cast<DictionaryEntry>(); |
cache.Add(resxKey, resxs, new CacheItemPolicy() { Priority = CacheItemPriority.NotRemovable }); |
