项目中常用封装方法（信息提示、权限验证、数据连接验证）

1、常用信息提示方法类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Data;
using System.Web.SessionState;

namespace ECS.Utility
{
    public class JScript
    {
        protected static HttpResponse Response;
        protected static HttpSessionState Session;
        public JScript()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }

        /// <summary>
        /// 提示信息

        /// <param name="msg">提示信息</param>
        public static void ShowAlert(System.Web.UI.Page page, string msg)
        {
            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>alert('" + msg + "');</script>");
        }

        /// <summary>
        /// 注册脚本提示信息
        /// </summary>
        /// <param name="page">this</param>
        /// <param name="msg">提示信息</param>

        }

        /// <summary>
        /// 刷新页面并且弹出提示信息

        public static void ShowRefresh(System.Web.UI.Page page, string msg)
        {

            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>location.reload();alert('" + msg + "。');</script>");
        }

        /// <summary>
        /// 刷新页面并且弹出提示信息并注册脚本
        /// </summary>
        /// <param name="page">this</param>

        public static void ShowRefresh(System.Web.UI.Page page, string msg, string script)
        {
            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>location.reload();" + script + "</script>");
        }

        /// <summary>
        /// 刷新父页面并且弹出提示信息
        /// </summary>
        /// <param name="page">this</param>
        /// <param name="msg">提示信息</param>
        public static void ShowParentRefresh(System.Web.UI.Page page, string msg)
        {
            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>parent.location.reload();alert('" + msg + "。');</script>");
        }

        /// <summary>
        /// 刷新父页面后提示信息执行脚本
        /// </summary>

        /// <param name="script">注册脚本</param>
        public static void ShowParentRefresh(System.Web.UI.Page page, string msg, string script)

            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>parent.location.reload();alert('" + msg + "。');" + script + "</script>");
        }




        /// <summary>
        ///  注册脚本

        {
            page.ClientScript.RegisterStartupScript(page.GetType(), "msg", "<script>" + script + "</script>");
        }



        /// <summary>
        /// 弹出JavaScript小窗口
        /// </summary>
        /// <param name="js">窗口信息</param>
        public static void Alert(string message)
        {
            message = StringUtil.DeleteUnVisibleChar(message);
            string js = @"<Script language='JavaScript'>
                    alert('" + message + "');</Script>";
            HttpContext.Current.Response.Write(js);
        }

        public static void AlertAndRedirect(string message, string toURL)
        {
            string js = "<script language=javascript>alert('{0}');window.location.replace('{1}')</script>";
            HttpContext.Current.Response.Write(string.Format(js, message, toURL));
        }

        public static void Redirect(string toURL)
        {
            string js = "<script language=javascript>window.location.replace('{0}')</script>";
            HttpContext.Current.Response.Write(string.Format(js, toURL));
        }

        /// <summary>		
        /// 函数名:GotoParentWindow

        }
    }

2、页面权限校验

    /// <summary>
    /// 判断权限
    /// </summary>
    /// <param name="DisplayName">权限名称</param>
    public static void MyRole(string DisplayName)
    {
        bool bfg = false;
        IYUEJIE.Model.A_AdminUser AdminUserModel = HttpContext.Current.Session["AdminUser"] as IYUEJIE.Model.A_AdminUser;//得到登录LoginId
        DataTable dt = new DBHelper().GetDataSet("SELECT * FROM  View_SysRoleList where  RoleID='" + AdminUserModel.RoleId + "' and [Custom
