解决方案

的ConfigurationSettings.AppSettings 是的过时，你应该使用< A HREF =htt​​ps://msdn.microsoft.com/en-us/library/system.configuration.configurationmanager.appsettings(v=vs.110).aspx>配置的管理的.AppSettings ，而不是（你将需要添加一个引用 System.Configuration ）

  int值= Int32.Parse（ConfigurationManager.AppSettings [StartingMonthColumn]）; 
  

如果您仍然有问题，在应用设置阅读然后检查你的应用的.config 文件名是否正确。具体来说，应根据即 MyApp.exe.config 执行的程序集被命名，并应驻留在同一目录 MyApp.exe的。

I am trying to read StartingMonthColumn and CategoryHeadingColumn from the below app.config file using the code

ConfigurationSettings.AppSettings["StartingMonthColumn"]

but it is returning null, also ConfigurationSettings.AppSettings.Count returns zero

Please help me to read this in my windows application

<configuration>
    <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="CTARepository.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <userSettings>
        <CTARepository.Properties.Settings>
            <setting name="Setting" serializeAs="String">
                <value />
            </setting>
        </CTARepository.Properties.Settings>
    </userSettings>
    <appSettings>
        <add key="StartingMonthColumn" value="7"/>
        <add key="CategoryHeadingColumn" value="1"/>
    </appSettings>
</configuration>

解决方案

ConfigurationSettings.AppSettings is obsolete, you should use ConfigurationManager.AppSettings instead (you will need to add a reference to System.Configuration)

int value = Int32.Parse(ConfigurationManager.AppSettings["StartingMonthColumn"]);

If you still have problems reading in your app settings then check that your app.config file is named correctly. Specifically, it should be named according to the executing assembly i.e. MyApp.exe.config, and should reside in the same directory as MyApp.exe.
