ResourceManager.GetString 在单元测试中失败 [英] ResourceManager.GetString fails in unit tests

问题描述

我用两个 resx 创建了一个程序集 MyResources:

I've created an assembly MyResources with two resx:

• MyResources.resx
• MyResources.en.resx

在程序集中，我添加了一个处理程序类，其中包含一个 ResHandler 类中的 GetString 包装器:

Inside the assembly I've added a handler-class containing a GetString-wrapper inside a ResHandler-class:

    public string GetResString(string key)
    {            
        return _manager.GetString(key, _culture);
    }

_culture 只是一个可以从外部设置的属性:

_culture is simply a property which can be set from outside:

    public void ChangeCulture(CultureInfo newCulture)
    {            
        _culture = newCulture;
    }

如果我从控制台应用程序调用此代码，则一切正常:

If I call this code from a lets say console-app, everything works fine:

    var res = ResHandler.GetInstance(Guid.NewGuid().ToString());
    //change the culture to "en"
    res.ChangeCulture(new CultureInfo("en"));
    Console.WriteLine(res.GetResString("TXT_0001"));

此代码将英文版本写入控制台.但是，如果我从单元测试方法中调用完全相同的代码，则会出现 MyResources.resx 的内容.这里有什么问题?单元测试是否由于某种原因无法做到这一点?

This code writes the english version to the console. However, if I call the exact same code from a unit-test-method, the contents of the MyResources.resx will appear. Whats wrong here? Are unit-tests unable to do this for some reason?

推荐答案

请注意附属程序集存储在包含 EXE 的目录的子目录中.就像英语的en-US"或en".问题是，您的测试在不同的 EXE 下运行，mstest.exe 而不是您的 app.exe.因此，它不会找到附属程序集.我认为您可以通过在测试设置中使用 Deployment 来解决这个问题，不确定.

Beware that satellite assemblies are stored in a subdirectory of the directory that contains the EXE. Like "en-US" or "en" for English. Problem is, your test runs under a different EXE, mstest.exe and not your app.exe. It will therefore not find the satellite assembly. I think you can fix this by using Deployment in the test settings, not sure.
