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：
/// 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：
