页面中用Context.Handler传递

Posted 2020-09-16 赵弘添

   最近被WCF弄得身心疲惫。今天抽空看了一下页面传值的一些技巧。传统的cookie session 什么的就不介绍了

今天介绍Context的用法

首先要应用using System.Runtime.Remoting.Contexts;命名空间

public static string strname = "";

//静态变量传递
            strname = "wtyTest";
            Server.Transfer("WebFormD2.aspx");
           
            //接收页面
            string request = string.Empty;
            request = WebFormD1.strname;

  //Context.Handler获取控件     

       if (Context.Handler is WebFormE1)
            {
                //获得页面对象
                WebFormE1 poster = (WebFormE1)Context.Handler;
                //取得控件
                TextBox.Text =(TextBox)poster.FindControl("TextBox1")).Text;
            }

//Context.Handler获取公共变量

            //发送页面代码
             public static string strname = ""; 
            strname = "wtyTest";
            Server.Transfer("WebFormD2.aspx");
            
            //接收页面代码
            if (Context.Handler is WebFormE1)
            {
                //获得页面对象
                WebFormE1 poster = (WebFormE1)Context.Handler;
                TextBox.Text =poster.strname;
            }

//Context.items变量

            //发送页面代码
            Context.Items["name"]="wtytest";
            Server.Transfer("WebFormD2.aspx");
            
            //接收页面代码
            if (Context.Handler is WebFormE1)
            {
               
                //
                TextBox.Text =Context.Items["name"].ToString();
            }
