.NET MVC本地化（resourceprovider）实施工作不正常 [英] .NET MVC Localization (resourceprovider) implementation not working correctly

问题描述

我目前正在实施一个本地化的网站。我创建了一个自定义的ResourceProvider +工厂为存储在数据库中的资源。这一切工作，我存储的数据如下：

  RESOURCEID | URL（空）|型（空）|名称|文化（空）|值
     1 | NULL |通用|测试| NULL |你好
     2 | 〜/查看/产品/的Index.aspx | NULL |产品| NULL |制品
 

我已经存储在全球（测试）和上面的例子中本地（产品）的资源，如果我是正确的？

我用这个实现ResourceHelpers的（的链接）（code以下）。这应该让我来显示基于以下code资源：

的 环球资源：该作品（输出：你好）的

 ＆LT;％= Html.Resource（通用，测试）％GT;
 

的 本地资源：这里的问题是，这是不行的，这是怎么回事？的

 ＆LT;％= Html.Resource（产品）％GT;
 

如预期的第一个code样本输出嗨。然而，第二个code样品抛出异常（ 与资源对象键产品没有被发现。的）（我标志着$ C $行下面C〜17行）。
的 是后，我打电话给在第二行〜/查看/产品/ Index.aspx的的

这里的助手code我使用的：

 ＆LT; System.Runtime.CompilerServices.Extension（）＆GT; _
公共职能资源（BYVAL作为的HtmlHelper的HtmlHelper，BYVAL前pression作为字符串，BYVAL的ParamArray ARGS作为对象（））作为字符串
    昏暗virtualPath作为字符串= GetVirtualPath（的HtmlHelper）
    返回GetResourceString（htmlhelper.ViewContext.HttpContext，前pression，virtualPath，参数）

    返回GetResourceString（controller.HttpContext，前pression，〜/，参数）

    昏暗的环境作为新的前pressionBuilderContext（virtualPath）

    下一个    结果= webFormViewEngine.FindView（controllerContext，的viewName，，假）
    如果result.View状态并没有任何再
        结果= webFormViewEngine.FindPartialView（controllerContext，的viewName，假）

    返回结果
结束功能专用功能GetViewName（BYVAL视图作为IVIEW）作为字符串
    昏暗的viewName作为字符串=没有
    如果TypeOf运算的观点是WebFormView然后
        的viewName = Path.GetFileNameWithoutExtension（（DirectCast（查看，WebFormView））。ViewPath）
    万一
    返回的viewName
结束功能
 

解决方案

原来的资源没有被请求时自动保存..

i'm currently implementing a localized website. I've created a custom ResourceProvider + Factory for storing resources in a database. This all works, i'm storing data as follows:

resourceid | url (null)                  | type (null) | name     | culture (null) | value
     1     | NULL                        | Common      | Test     | NULL           | Hi
     2     | ~/Views/Products/Index.aspx | NULL        | Products | NULL           | Products

I've stored a Global (Test) and a Local (Products) resource in the above sample if i'm correct?

I'm using this implementation of ResourceHelpers (link) (code below). This should allow me to display resources based on the following code:

Global resources: This works (output: "Hi")

<% =Html.Resource("Common, Test") %>

Local resources: Here is the problem, this doesn't work, what's going on??

<% =Html.Resource("Products") %>

The first code sample outputs "Hi" as expected. However the second code sample throws an exception (The resource object with key 'Products' was not found.) (i've marked the line in code below ~line 17). yes, i'm calling the second line on "~/Views/Products/Index.aspx"

Here's the Helper code i'm using:

<System.Runtime.CompilerServices.Extension()> _
Public Function Resource(ByVal htmlhelper As HtmlHelper, ByVal expression As String, ByVal ParamArray args As Object()) As String
    Dim virtualPath As String = GetVirtualPath(htmlhelper)
    Return GetResourceString(htmlhelper.ViewContext.HttpContext, expression, virtualPath, args)
End Function

<System.Runtime.CompilerServices.Extension()> _
Public Function Resource(ByVal controller As Controller, ByVal expression As String, ByVal ParamArray args As Object()) As String
    Return GetResourceString(controller.HttpContext, expression, "~/", args)
End Function

Private Function GetResourceString(ByVal httpContext As HttpContextBase, ByVal expression As String, ByVal virtualPath As String, ByVal args As Object()) As String
    Dim context As New ExpressionBuilderContext(virtualPath)
    Dim builder As New ResourceExpressionBuilder()

    'The following line throws the exception
    Dim fields As ResourceExpressionFields = DirectCast(builder.ParseExpression(expression, GetType(String), context), ResourceExpressionFields)

    If Not String.IsNullOrEmpty(fields.ClassKey) Then
        Return String.Format(DirectCast(httpContext.GetGlobalResourceObject(fields.ClassKey, fields.ResourceKey, CultureInfo.CurrentUICulture), String), args)
    End If

    Return String.Format(DirectCast(httpContext.GetLocalResourceObject(virtualPath, fields.ResourceKey, CultureInfo.CurrentUICulture), String), args)
End Function

Private Function GetVirtualPath(ByVal htmlhelper As HtmlHelper) As String
    Dim virtualPath As String = Nothing
    Dim controller As Controller = TryCast(htmlhelper.ViewContext.Controller, Controller)

    If controller IsNot Nothing Then
        'Dim result As ViewEngineResult = FindView(controller.ControllerContext, htmlhelper.ViewContext.ViewName)
        Dim result As ViewEngineResult = FindView(controller.ControllerContext, GetViewName(htmlhelper.ViewContext.View))
        Dim webFormView As WebFormView = TryCast(result.View, WebFormView)

        If webFormView IsNot Nothing Then
            virtualPath = webFormView.ViewPath
        End If
    End If

    Return virtualPath
End Function

Private Function FindView(ByVal controllerContext As ControllerContext, ByVal viewName As String) As ViewEngineResult
    ' Result
    Dim result As ViewEngineResult = Nothing

    ' Search only for WebFormViewEngine
    Dim webFormViewEngine As WebFormViewEngine = Nothing
    For Each viewEngine In ViewEngines.Engines
        webFormViewEngine = TryCast(viewEngine, WebFormViewEngine)

        If webFormViewEngine IsNot Nothing Then
            Exit For
        End If
    Next

    result = webFormViewEngine.FindView(controllerContext, viewName, "", False)
    If result.View IsNot Nothing Then
        result = webFormViewEngine.FindPartialView(controllerContext, viewName, False)
    End If

    ' Return
    Return result
End Function

Private Function GetViewName(ByVal view As IView) As String
    Dim viewName As String = Nothing
    If TypeOf view Is WebFormView Then
        viewName = Path.GetFileNameWithoutExtension((DirectCast(view, WebFormView)).ViewPath)
    End If
    Return viewName
End Function

Turns out the resources weren't being saved automatically during the request..
