.NET 中的多语言应用程序

Question

尽管我有多年的 OOP 经验，但我是 C# 的新手。

对于一个处于设计阶段的项目，我被选中来研究如何在 C# 下实现多语言。对于该项目，我目前正在使用 Microsoft Visual Studio 2010 Express...

到目前为止我所做的事情

我阅读了有关此主题的几篇文章，例如 System.Resources 常见问题解答，.NET 中的多语言应用程序 或 C# 多语言支持，但是运行我的演示仍然遇到问题。

我的演示在没有包含所有文化（ar-SA、en-UK、de-DE、no、sv-SE 和 tr）硬编码文本的资源文件的情况下工作。当我尝试使用资源文件时遇到问题。

我如何尝试解决这个问题

为了解决这个问题，我为每种区域性创建了一个资源文件，名为 Resource..resx。所有教程都不是为 MS VS 2010 编写的，因此资源上没有有关组合框的信息，我将其保留为默认值（“无代码生成”）而不是“内部”。 :-(

现在，我有了六种语言的资源文件：

Resource.ar-SA.resx
Resource.de-DE.resx
etc.

我确定了 IDE 生成的 *.resources 文件，并根据所选语言确定了每个文件的路径。

当我运行代码时，我陷入困境消息

MainWindow:DetermineResourceManager(): Exception: System.BadImageFormatException: Im Modul wurde ein Assemblymanifest erwartet. (Ausnahme von HRESULT: 0x80131018)
   bei System.Reflection.RuntimeAssembly.nLoadFile(String path, Evidence evidence)
   bei System.Reflection.Assembly.LoadFile(String path)
   bei WpfApplication1.MainWindow.DetermineResourceManager() in C:\Documents and Settings\z002zatp\My Documents\Visual Studio 2010\Projects\WpfApplication1\WpfApplication1\MainWindow.xaml.cs:Zeile 136.

“所以，缺少一个所谓的程序集清单”

我的问题

我该怎么做才能让 IDE 正确创建程序集清单

代码

有问题的行被标记 ？我检查了下面的文件。 C:\Documents and Settings\z002zatp\My Documents\Visual Studio 2010\Projects\WpfApplication1\WpfApplication1\obj\x86\Debug 确实存在。
