页面加载的时候会先调用locked方法
- C# code
static object obj = new object(); protected string locked() { CMLogger m_logger = CMLogger.GetInstance(); string errcode = "0000"; lock (obj) { string FindVPN_Address = System.Configuration.ConfigurationManager.AppSettings["VPN_Address"]; string VPN_Address = ""; string MasterVPN_Address = System.Configuration.ConfigurationManager.AppSettings["Master_VpnAddress"]; #region if (FindVPN_Address == MasterVPN_Address) { VPN_Address = FindVPN_Address; } else if (!SetParam(MasterVPN_Address)) { ChangeChannel changechannel = new ChangeChannel(); changechannel.ChangeVPN_Address(MasterVPN_Address); VPN_Address = MasterVPN_Address; } else { VPN_Address = FindVPN_Address; } if (SetParam(VPN_Address)) { int count = 0; for (int i = 0; i < 2; i++) { if (SetParam(VPN_Address)) { count++; if (count == 2) { ChangeChannel channle = new ChangeChannel(); errcode = channle.ChangeBocChannel(ConfigurationManager.AppSettings["MonitorSiteName"]); } } else break; } } return errcode; #endregion } }后边会对config中VPN_Address这个节点进行修改
- C# code
public void ChangeVPN_Address(string NPN_Address) { CMLogger m_logger = CMLogger.GetInstance(); try { Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/", ConfigurationManager.AppSettings["MonitorSiteName"]); AppSettingsSection appseting = (AppSettingsSection)config.GetSection("appSettings"); appseting.Settings["Bank_VPNRuntime"].Value = NPN_Address; config.Save(); ConfigurationManager.RefreshSection("appSettings"); config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~"); appseting = (AppSettingsSection)config.GetSection("appSettings"); appseting.Settings["VPN_Address"].Value = NPN_Address; config.Save(); ConfigurationManager.RefreshSection("appSettings"); } catch (Exception ex) { m_logger.WriteDebugLog("保存失败【" + ex + "】"); } }当多个进程同时访问config的时候，由于前边加了lock，所以会第二个以后的进程会等待第一个结束后才会继续执行，但是当第一个进程修改过config后，第二个进程执行时拿到的config节点的值还是未修改的，这个是怎么回事，坐等给为大神指点

config中保存一些小的,不用修改的数据,比如sql连接字符串,定义某程序需要读取的路径等等 .
你需要修改的数据还是放到数据库中吧,需要的时候直接从数据库读取

貌似xml可以在这里面应用一下，问题出现的原因就是因为数据修改。linq to xml
