C# Page用于各页面继承功能实例

本文实例讲述了C# Page用于各页面继承功能的实现方法。分享给大家供大家参考。具体方法如下:

IBasePage.cs文件如下:

/// <summary>

/// 用于页面或用户控件

/// </summary>

public interface IBasePage

{

        /// <summary>

        /// 数据缓存类

        /// </summary>

        DbCache CacheHelp { get; }

        /// <summary>         /// 页面视图,用于页面级别访问,模仿MVC         /// </summary>         ViewDataDict ViewData { get; }

        /// <summary>         /// 获取DataTable.Rows,此方法不会出错异常         /// </summary>         /// <param name="pName">数据名称</param>         /// <returns></returns>         DataRowCollection ViewDataRows(string pName);

        /// <summary>         /// 1:true否则false         /// </summary>         /// <param name="pName"></param>         /// <returns></returns>         bool IsViewData(string pName);

        /// <summary>         /// URL参数类         /// </summary>         UrlQuery UQ { get; }

        /// <summary>         /// 页面搜索关键词,搜索关键词是最基本功能,故在这里放一个字段         /// </summary>         string searchStr { get; set; }

        /// <summary>         /// 权限使用次数         /// </summary>         int UserFunCount { get; set; }

        /// <summary>         /// 数据库链接次数         /// </summary>         int DbCount { get; set; }

        /// <summary>         /// 用与判断增加style,js等是否已重复添加         /// </summary>         /// <param name="pName"></param>         /// <returns></returns>         TempListHandler TempList { get; } }

BasePage.cs文件如下:

/// <summary>

/// 整站页面基础类

/// </summary>
