C# 不重启程序修改并保存配置文件（appSettings节点）

private static void UpdateAppConfig(string newKey, string newValue) { bool isModified = false; foreach (string key in ConfigurationManager.AppSettings) { if (key == newKey) { isModified = true; } } Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); if (isModified) { config.AppSettings.Settings.Remove(newKey); } config.AppSettings.Settings.Add(newKey, newValue); config.Save(ConfigurationSaveMode.Modified); ConfigurationManager.RefreshSection("appSettings"); }
