How to modify AppSettings configuration values from your app code

You can easily change any AppSettings value in web.config during runtime from your C# code by using WebConfigurationManager.

Configuration configuration = WebConfigurationManager.OpenWebConfiguration("~");

AppSettingsSection appSettings = (AppSettingsSection)configuration.GetSection("appSettings");

 

if (appSettings != null)

 {

   appSettings.Settings["SetupRan"].Value = "true";

   configuration.Save();

 }

 

This will set SatupRan to true in web.config

<appSettings>

    <add key="SetupRan" value="true"/>

</appSettings>

 

WebConfigurationManager Provides access to Web application’s configuration files and the GetSection methods can be used to get any section in web.config.
