set ref app use code val 文件的 copy 代碼
string settingValue = ConfigurationManager.AppSettings.Get("setting1");
string settingValue = config.AppSettings.Settings["setting1"].Value;
config.AppSettings.Settings["setting1"].Value = "123";
config.Save(ConfigurationSaveMode.Modified);
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="setting1" value="123" />
</appSettings>
</configuration>
讀配置文件 方法(1)
//ConfigurationManager.RefreshSection("appSettings");string settingValue = ConfigurationManager.AppSettings.Get("setting1");
讀配置文件 方法(2)
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);string settingValue = config.AppSettings.Settings["setting1"].Value;
寫配置文件
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);config.AppSettings.Settings["setting1"].Value = "123";
config.Save(ConfigurationSaveMode.Modified);
App.config
<?xml version="1.0" encoding="utf-8" ?><configuration>
<appSettings>
<add key="setting1" value="123" />
</appSettings>
</configuration>
註：不要試圖用這種方法來寫配置文件，這種方法根本寫不了配置文件的:
ConfigurationManager.AppSettings.Set("setting1", "123");
