Configuration configuration = ConfigurationManager.
OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);
configuration.AppSettings.Settings["logPath"].Value = DateTime.Now.ToString("yyyy-MM-dd");
configuration.Save();
ConfigurationManager.RefreshSection("appSettings");

I believe this is what you are looking for:

using System.Configuration;

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
                config.AppSettings.Settings["isScreenCaptureMode"].Value = "true";
                config.Save(ConfigurationSaveMode.Modified);
                ConfigurationManager.RefreshSection("appSettings");
