（实战篇）如何实现换肤和全站统一友好的错误页面

承接上一篇的如何实现多语言，这一篇我们讨论的是如何实现换肤，和实现全站统一友好的错误页面，这个比较简单，

废话不说，直接看思路和实现方法：

（1）先说换肤：

  总体思路是在基类pagebase里实现，构造方法里重载某个事件

 protected PageBase()
        {
            this.PreInit += new EventHandler(this.Page_PreInit);
        }
   public void Page_PreInit(object sender, EventArgs e)
        {
            if (FWConfig.CurContext.Session[FWConfig.UserInfoSession] != null)
            {
                string cTheme = Utility.LoginUserInfo.AppTheme;
                string SkinStr = ConfigurationManager.AppSettings["Skin"];
                if (CommonFunc.IsNullString(cTheme) || !SkinStr.Contains(cTheme))
                {
                    cTheme = EnumUtil.SkinType.DefaultTheme.ToString();
                }
                this.Page.Theme = cTheme;
            }
           // else 设置默认样式
         } 

 

 （2）再说统一友好的错误页面，重载OnError事件

 protected override void OnError(EventArgs e)
        {
            string strRootPath = this.Page.Request.ApplicationPath;
 
            //取得当前具体异常
            try
            {
                if (null != this.Server.GetLastError())
                {
                    Exception exError = this.Server.GetLastError().GetBaseException();
                    LogInfoEntity logInfoEntity = new LogInfoEntity
                   {
                       AppName = ConfigurationManager.AppSettings[ "SystemCode"],
                       OperatorUserID = Utility.LoginUserInfo.LoginID,  
                        RequestURL = this.Request.Url.ToString(),
                       MachineIP = this.Request.UserHostAddress,
                       Message = exError.Message,
                       Exception = exError.ToString(),
                       AppCode = ConfigurationManager.AppSetting[ "SystemCode"] };
                    //系统名称
                    //系统编码
                    LogUtil.Error(logInfoEntity, exError);
 
                    //给管理员发送错误邮件
                    #region 给管理员发送错误邮件
 
                    string strReceivers = CommonFunc.ObjectToNullStr(ConfigurationManager.AppSettings["OAErrorMsgRecivers"]);
                    string[] strReceiver = strReceivers.Split(',');
                    for (int i = 0; i < strReceiver.Length; i++)
                    {
                        if (CommonFunc.IsNotNullString(strReceiver[i]))
                        {
                            NotifyMsg msgEntity = new NotifyMsg
                            {
                                AppCode = "OA",
                                IsSended = false,
                                MsgXML = this.CreateWarmXML(exError.Message),
                                NotifyType = 1,
                                Reciver = strReceiver[i],
                                ReciveTime = DateTime.Now,
                                Sender = "",
                                SendTime = DateTime.Now,
                                Subject = "集团新OA系统出错Mail",
                                TempelateID = "OAErrorMsgTemplate"
                            };
 
                            new ProcTemplate().InsertNotifyMsg(msgEntity);
                        }
                    }
 
                    #endregion 给管理员发送错误邮件
 
                    this.Server.ClearError();
 
                    this.Page.Response.Redirect(strRootPath + "ErrorPage.aspx?errorMsg=" + exError.Message + "&url=" + CommonFunc.ObjectToNullStr(this.Request.Url));
                }
            }
            catch { }

  

以上是某个项目中的实现方式，当然方式有很都种，这个记录下来以供参考！
