How to use a App.config file in WPF applications?
提问by Edward Tanguay
I created a App.config file in my WPF application:
我在 WPF 应用程序中创建了一个 App.config 文件：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appsettings>
<add key="xmlDataDirectory" value="c:\testdata"/>
</appsettings>
</configuration>
Then I try to read the value out with this:
然后我尝试用这个读取值：
string xmlDataDirectory = ConfigurationSettings.AppSettings.Get("xmlDataDirectory");
But it says this is obsolete and that I should use ConfigurationManager which I can't find, even searching in the class view.
但它说这已经过时了，我应该使用我找不到的 ConfigurationManager，甚至在类视图中搜索。
Does anyone know how to use config files like this in WPF?
有谁知道如何在 WPF 中使用这样的配置文件？

You have to reference the System.Configurationassembly that is in GAC.
您必须引用System.ConfigurationGAC 中的程序集。
Use of ConfigurationManageris not WPF-specific: it is the privileged way to access configuration information for any type of application.
的使用ConfigurationManager不是 WPF 特定的：它是访问任何类型应用程序配置信息的特权方式。

In your app.config, change your appsetting to
在您的 中app.config，将您的 appsetting 更改为
<applicationSettings>
<WpfApplication1.Properties.Settings>
<setting name="appsetting" serializeAs="String">
<value>c:\testdata.xml</value>
</setting>
</WpfApplication1.Properties.Settings>
</applicationSettings>
Then, in the code-behind,
然后，在代码隐藏中，
string xmlDataDirectory = WpfApplication1.Properties.Settings.Default.appsetting.ToString()

This also works
这也有效

You have to add the reference to System.configurationin your solution. Also, include using System.Configuration;. Once you do that, you'll have access to all the configuration settings.
您必须System.configuration在解决方案中添加对的引用。此外，包括using System.Configuration;. 完成此操作后，您将可以访问所有配置设置。

You have to reference System.Configurationvia explorer (not only append using System.Configuration). Then you can write:
您必须System.Configuration通过资源管理器进行引用（不仅是 append using System.Configuration）。然后你可以写：
string xmlDataDirectory =
System.Configuration.ConfigurationManager.AppSettings.Get("xmlDataDirectory");
Tested with VS2010 (thanks to www.developpez.net). Hope this helps.
用 VS2010 测试（感谢 www.developpez.net）。希望这可以帮助。

You can change configuration file schema back to DotNetConfig.xsdvia properties of the app.configfile. To find destination of needed schema, you can search it by name or create a WinForms application, add to project the configuration file and in it's properties, you'll find full path to file.
您可以DotNetConfig.xsd通过app.config文件的属性将配置文件架构更改回。要查找所需架构的目标，您可以按名称搜索它或创建一个 WinForms 应用程序，将配置文件添加到项目中，并在其属性中找到文件的完整路径。

Added System.Configuartion to my project
将 System.Configuartion 添加到我的项目中
Added using System.Configuration statement in file at top
在顶部的文件中添加 using System.Configuration 语句
Then used below statement
然后使用下面的语句
string queuePath = ConfigurationManager.AppSettings["POCPublishSubscribeQueueName"].ToString();
