我的Visual Studio应用程序的用户可能会单击按钮将应用程序恢复为出厂默认设置。在工厂，我们配置应用程序，然后单击另一个按钮将该配置设置为出厂默认设置为当前配置设置。
但是，如果我们将配置设置（XML格式）保存到settings.settings，它们将存储在我们自己的用户文件夹中（而不是Visual Studio项目文件夹中），并且用户不会收到它们。< / p>
（settings.settings使用设计时存储的默认值。）
我们需要将出厂默认值存储在可执行文件中包含的文件中，或随其一起分发。我们可以在发行版附带的factorydefaultconfig.xml文件中编写出厂默认值，但我认为您可能知道更好的方法。
现在我正在研究应用程序配置文件以查看我应该使用的是什么。

Yep App设置或滚动自己是我们过去处理此问题的方式。将System.Configuration的引用添加到项目中，然后使用以下命令：
ConfigurationManager.AppSettings.Set("lang", "English"); //Set
string getLang = ConfigurationManager.AppSettings["lang"]; //Get
对于App.config：
<configuration>
<appSettings>
<add key="lang" value="English"/>
</appSettings>
</configuration>

以防万一你想尝试一下。这是我写的一个名为ConfigHub的类，用于完成您所说的内容。它也使用锁，以确保您不会遇到文件使用错误：

请注意。您需要首先在项目中构建文件并删除XML标头。如下所示（例如：MyConfigFile.xml） - 顶部没有xml标签，如（）。最后，确保将xml配置文件设置为始终复制：
<Config>
<ValueName>Value</ValueName>
</Config>
