private void AccessAppSettings()
{
//获取Configuration对象
Configuration config = System.Configuration.ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
//根据Key读取<add>元素的Value
string name = config.AppSettings.Settings["name"].Value;
//写入<add>元素的Value
config.AppSettings.Settings["name"].Value = "xieyc";
//增加<add>元素
config.AppSettings.Settings.Add("url", "http://www.xieyc.com");
//删除<add>元素
config.AppSettings.Settings.Remove("name");
//一定要记得保存，写不带参数的config.Save()也可以
config.Save(ConfigurationSaveMode.Modified);
//刷新，否则程序读取的还是之前的值（可能已装入内存）
System.Configuration.ConfigurationManager.RefreshSection("appSettings");
