sub appsettings in the appsetting node c#
提问by Tony Germanos
I am using the app.config file that is created with a console application and I can read the val1 of the key1 using the ConfigurationSettings.AppSettings["key1"].ToString()
我正在使用通过控制台应用程序创建的 app.config 文件，我可以使用以下命令读取 key1 的 val1 ConfigurationSettings.AppSettings["key1"].ToString()
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
</startup>
<appSettings>
<add key="key1" value="val1" />
<add key="key2" value="val2" />
</appSettings>
</configuration>
but I have too many keys and values that I want to make them categorized.
但我有太多的键和值，我想让它们分类。
I found something that is difficult to use in my application since I want to access the keys in a similar way to the above one
我发现一些难以在我的应用程序中使用的东西，因为我想以与上述类似的方式访问密钥
Showing all nodes and can't read a node without getting all the nodes
for example what I want to do:
例如我想做什么：
<appSettings>
<Section1>
<add key="key1" value="val1" />
</Section1>
<Section2>
<add key="key1" value="val1" />
<Section2>
</appSettings>
and if there is a way to access it using
ConfigurationSettings.AppSettings["Section1"].["key1"].ToString()
如果有办法使用它访问它
ConfigurationSettings.AppSettings["Section1"].["key1"].ToString()

You can add custom sections in app.config without writing additional code. All you have to do is "declaring" new section in configSectionsnode like that
您可以在 app.config 中添加自定义部分，而无需编写额外的代码。您所要做的就是configSections像这样在节点中“声明”新部分
<configSections>
<section name="genericAppSettings" type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</configSections>
and then you can define this section filling it with keys and values:
然后你可以定义这个部分，用键和值填充它：
<genericAppSettings>
<add key="testkey" value="generic" />
<add key="another" value="testvalue" />
</genericAppSettings>
To get value of a key from this section you have to add System.Configurationdll as reference to your project, add usingand use GetSectionmethod. Example:
要从此部分获取键的值，您必须添加System.Configurationdll 作为对项目的引用，添加using和使用GetSection方法。例子：
using System.Collections.Specialized;
using System.Configuration;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
NameValueCollection test = (NameValueCollection)ConfigurationManager.GetSection("genericAppSettings");
string a = test["another"];
}
}
}
Nice thing is that you can easily make groups of sections if you need this:
不错的是，如果您需要，您可以轻松地将部分分组：
<configSections>
<sectionGroup name="customAppSettingsGroup">
<section name="genericAppSettings" type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
// another sections
</sectionGroup>
</configSections>
<customAppSettingsGroup>
<genericAppSettings>
<add key="testkey" value="generic" />
<add key="another" value="testvalue" />
</genericAppSettings>
// another sections
</customAppSettingsGroup>
If you use groups, to access sections you have to access them using {group name}/{section name}format:
如果您使用组，要访问部分，您必须使用{group name}/{section name}格式访问它们：
NameValueCollection test = (NameValueCollection)ConfigurationManager.GetSection("customAppSettingsGroup/genericAppSettings");

AFAIK you can implement a custom section outside of the appsettings. For example, frameworks like Autofac and SpecFlow use these kind of sessions to support their own configuration schema. You can take a look on thisMSDN article to understand how to do that. Hope that helps.
AFAIK 您可以在 appsettings 之外实现自定义部分。例如，像 Autofac 和 SpecFlow 这样的框架使用这些类型的会话来支持他们自己的配置模式。您可以查看此MSDN 文章以了解如何执行此操作。希望有帮助。
