读配置文件 方法(2)

写配置文件
1 2 3 | Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); config.AppSettings.Settings["setting1"].Value = "123"; config.Save(ConfigurationSaveMode.Modified); |
App.config
1 2 3 4 5 6 | <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="setting1" value="123" /> </appSettings> </configuration> |
注：不要试图用这种方法来写配置文件，这种方法根本写不了配置文件的:
ConfigurationManager.AppSettings.Set(“setting1”, “123”);
