cookie,session,application--[Asp.Net]

Cookie

        写入：

		HttpCookie nc=new HttpCookie("newcookie');//--实例化httpcookie
		Nc.values[" name"] =xx;//--赋值
		Response.cookies.Add(nc);//--写入

        读取：

		HttpCookie getcook=request.Cookies["newcookie"];
		Response.write(getcook.value["name"]);

 

Application

1.在global全局里面的设置初值Application["a"]= 0;

        2.加载页面里面，

			Application.Lock();
		        Application["a"] = (int)Application["a"] + 1;
		          //对象类型强转成整数类型
			Application.UnLock();//解锁
			
		        Response.Write(Application ["a"]);

        3.global

		
		void Application_Start(object sender, EventArgs e)
		        {
		            // 在应用程序启动时运行的代码
		          
		            Application.Lock();
		            Application["a"] = 0;
		            Application.UnLock();
		        }

session

         1.创建：global同application

         2.前台直接调用：Response.Write("<br>"+Session["name"]);
