C# 在配置文件中使用常量而不是字符串数组

相反，我需要使用常量来应用

app.config

文件中的配置设置

App.config文件：

string[] sectionGroupNames = new string[] { "commonSwitches", "tfsSwitches", "customConfigurationSwitches", "QuiteModeSwitches" };

如何做到这一点？

如果不使事情复杂化，您可以在App.config中将所有值作为一个字符串，然后在代码中拆分：

App.config:

<sectionGroup name="commonSwitches">
 <section name="switchDefinitions" type="System.Configuration.DefaultSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> 
</sectionGroup> 
<sectionGroup name="tfsSwitches">
 <section name="switchDefinitions" type="System.Configuration.DefaultSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
 </sectionGroup>
 <sectionGroup name="customConfigurationSwitches">
 <section name="switchDefinitions" type="System.Configuration.DefaultSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
 </sectionGroup> 
<sectionGroup name="QuiteModeSwitches"> 
<section name="switchDefinitions" type="System.Configuration.DefaultSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> 
</sectionGroup>

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
        <appSettings>
            <add key="sectionGroupNames" value="commonSwitches, tfsSwitches, customConfigurationSwitches, QuiteModeSwitches"/>
        </appSettings>
</configuration>

不要在.config文件中定义，而是创建一个单独的xml/Json文件并存储数据。之后，您可以编写代码来读取该xml/json文件。

string[] sectionGroupNames = ConfigurationManager.AppSettings["sectionGroupNames"].Split(new [] { ", " }, StringSplitOptions.None);
