通用 (UWP) 应用程序中的 ConfigurationManager 和 AppSettings [英] ConfigurationManager and AppSettings in universal (UWP) app

问题描述

我想将 API 密钥存储在配置文件中而不将其签入源代码管理，并在我的 UWP 应用中读取数据.

I would like to store an API key in a configuration file without checking it into source control, and read the data in my UWP app.

一种常见的解决方案是将密钥存储在 .config 文件(例如 app.config 或 web.config)中并像这样访问它:

A common solution is to store the key in .config file (such as app.config or web.config) and access it like so:

var apiKey = ConfigurationManager.AppSettings.Get("apiKey");

我正在开发通用 Windows (UWP) 应用，但无法访问包含 ConfigurationManager 的 System.Configuration 命名空间.

I'm working on a Universal Windows (UWP) app and can't access the System.Configuration namespace that holds ConfigurationManager.

如何在 UWP 应用中访问 AppSettings?或者，在 UWP 应用中访问配置数据的最佳方式是什么?

How can I access AppSettings in UWP app? Alternatively, what's the best way to access configuration data in an UWP app?

推荐答案

在我的特定用例中，我需要使用源代码管理未跟踪的外部文件.有两种方法可以从资源或配置文件中访问数据.

In my specific use case I needed to use an external file that is not tracked by source control. There are two ways to access data from resource or configuration files.

一个是打开并解析一个配置文件.给定文件 sample.txt 和 Build Action Content(复制到输出目录 无关紧要)，我们可以用

One is to open and parse a configuration file. Given a file sample.txt with Build Action Content (Copy to Output Directory doesn't matter), we can read it with

var uri = new System.Uri("ms-appx:///sample.txt");
var sampleFile = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(uri);

或

var packageFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;
var sampleFile = await packageFolder.GetFileAsync("sample.txt");

紧随其后

var contents = await Windows.Storage.FileIO.ReadTextAsync(sampleFile);

或者，我们可以使用资源.向项目中添加一个名为 resourcesFile.resw 的新资源项.要访问数据，请使用:

Alternatively, we can use Resources. Add a new Resource item to the project, called resourcesFile.resw. To access data, use:

var resources = new Windows.ApplicationModel.Resources.ResourceLoader("resourcesFile");
var token = resources.GetString("secret");

我在博客文章中写了更详细的答案自定义资源文件在 UWP 中

I wrote more verbose answer in a blog post Custom resource files in UWP
