防止2次提交和事件统一管理【转】

在ASP.NET的应用设计中，有一个好的画面基类很重要，它可以实现如：权限验证，Session管理，共通画面控制等等。
在此介绍实现防止2次提交和事件统一管理
1：创建基础页面类
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WeTest.framework.common
{
    public class BasePage :Page
    {
        // 处理标记ID
        protected const string SyoRiFlg_NM = "SyoRiFlg_234u19798701872348374534543";

        // 处理函数
        protected virtual void Run_Gen_Act_Cmd(int pintActCmd)
        {
        }

        /// 画面实行函数（2次提交验证）
        protected void Gen_Act_Cmd(int pintActCmd)
        {
            // 处理中验证
        if (!IsSyoRiFlg)
            {
                // 处理标记设置
                SetSyoRiFlg();
                // 业务处理
                Run_Gen_Act_Cmd(pintActCmd);
                // 处理标记清空
                ClearSyoRiFlg();
            }
        }

        // 处理中标记
        public bool IsSyoRiFlg
        {
            get
            {
                bool blnSyoRi_Flg = false;
                if(Session[SyoRiFlg_NM] == null)
                {
                    Session[SyoRiFlg_NM] = blnSyoRi_Flg;
                    return blnSyoRi_Flg;
                }
                blnSyoRi_Flg = (bool)Session[SyoRiFlg_NM];
                return blnSyoRi_Flg;
            }
        }
        /// 业务处理中标记设置
        public void SetSyoRiFlg()
        {
            bool blnSyoRi_Flg = true;
            Session[SyoRiFlg_NM] = blnSyoRi_Flg;
        }
        // 业务处理中标记清空
        public void ClearSyoRiFlg()
        {
            bool blnSyoRi_Flg = false;
            Session[SyoRiFlg_NM] = blnSyoRi_Flg;
        }

    }

}


2：创建画面，继承上面的基类：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using WeTest.framework.common;
namespace WeTest
{
    // testForm1 概要説明。
    public class testForm1 : BasePage
    {
        protected System.Web.UI.WebControls.Button testBtn1;
    
        private const int ACTIVE_SEARCH = 1;

        private void Page_Load(object sender, System.EventArgs e)
        {
            
        }

        override protected void OnInit(EventArgs e)
        {
            InitializeComponent();
            base.OnInit(e);
        }

        private void InitializeComponent()
        {    
            this.testBtn1.Click += new System.EventHandler(this.testBtn1_Click);
            this.Load += new System.EventHandler(this.Page_Load);
        }

        private void testBtn1_Click(object sender, System.EventArgs e)
       {
            Gen_Act_Cmd(ACTIVE_SEARCH);
        }
        // 处理函数 处理命令
       protected override void Run_Gen_Act_Cmd(int pintActCmd)
        {
            try
            {
                switch(pintActCmd)
                {
                    case ACTIVE_SEARCH:
                    {
                        //To Do
                        break;
                    }
                }
            }
            catch(Exception ex)
            {
                //Log
                
            }
        }
    }
}
这样就可以简单的实现了！！！
这里面还需要，共同日志处理，消息处理等！
