This article describes the C # implementation of appsettings node read and modify the method, share to everyone for your reference. Here's how:
The key code is as follows:
The code is as follows:
public static string Getappsettingsvalue (String key)
{
Configurationmanager.refreshsection ("appSettings");
Return Configurationmanager.appsettings[key]?? String. Empty;
}
public static bool Updateappsettings (string key, String value)
{
var _config = configurationmanager.openexeconfiguration (Configurationuserlevel.none);
if (!_config. HasFile)
{
throw new ArgumentException ("The program configuration file is missing! ”);
}
Keyvalueconfigurationelement _key = _config. Appsettings.settings[key];
if (_key = = null)
_config. APPSETTINGS.SETTINGS.ADD (key, value);
Else
_config. Appsettings.settings[key]. Value = value;
_config. Save (configurationsavemode.modified);
return true;
}
I hope this article is helpful to everyone's C # programming.
