我正在使用这个类写入配置文件.代码已建立且应用程序启动,但每次检查app.config时,我都看不到任何内容.

可能是什么问题呢？

这是代码:

public class ConfigSettings
    {
        private ConfigSettings() { }

        public static string ReadSetting(string key)
        {
            return ConfigurationManager.AppSettings[key];
        }

        public static void WriteSetting(string key, string value)
        {
            // load config document for current assembly
            XmlDocument doc = loadConfigDocument();

            // retrieve appSettings node
            XmlNode node = doc.SelectSingleNode("//appSettings");

            if (node == null)
                throw new InvalidOperationException("appSettings section not found in config file.");

            try
            {
                // select the 'add' element that contains the key
                XmlElement elem = (XmlElement)node.SelectSingleNode(string.Format("//add[@key='{0}']", key));

                if (elem != null) …
