学习微软企业库存心得--总结

1：asp.net页面可以继承基类，可以把页面里中的页面加载事件与报错，日志等事件都写进基类，方便每个页面的登陆与共同的方法处理。

 例如基类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Diagnostics;

using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Logging;

        public bool IsLogin
        {
            get
            {
                return _isLogin;
            }
            private set
            {
                _isLogin = value;

        protected void Page_Error(object sender, EventArgs e)

            HandleException(ex, "ExceptionPolicy");

        {
            bool rethrow = false;
            var exManager = EnterpriseLibraryContainer.Current.GetInstance<ExceptionManager>();
            rethrow = exManager.HandleException(ex, policy);

            {
                this.RedirectPermanent("~/error.aspx");
            }
        }

        /// <summary>
        /// 展示子页面,可被子页面重写
        /// </summary>
        protected virtual void ShowPage()
        {
            //TODO 具体的业务逻辑
        }
