C# web页面之间传值的几种方式

1. 下面是一个例子
   private void Button1_Click(object sender, System.EventArgs e)
   {
   string s_url;
   s_url = "b.aspx?name=" + Label1.Text;
   Response.Redirect(s_url);
   }
   b.aspx中C#代码
   private void Page_Load(object sender, EventArgs e)
   {
   Label2.Text = Request.QueryString["name"];
   }
2.  
   query传值又分类post ,get格式如
   //post请求 
   string name = Request["name"].toString(); 
   string name =Request.Form.Get("name").toString(); 
   //get请求 
   string name = Request.QueryString["name"].toString(); 
   但我发现 无论是否是post与get传值都可用
   string name = Request["name"].toString();
3.  
   使用Application 对象变量
   a.aspx的C#代码
   private void Button1_Click(object sender, System.EventArgs e)
   {
   Application["name"] = Label1.Text;
   Server.Transfer("b.aspx");
   }
   b.aspx中C#代码
   private void Page_Load(object sender, EventArgs e)
   {
   string name;
   Application.Lock();
   name = Application["name"].ToString();
   Application.UnLock();
   }
4.  
   使用Session变量
   a.aspx的C#代码
   private void Button1_Click(object sender, System.EventArgs e)
   {
   Session["name"] = Label.Text;
   }
   b.aspx中C#代码
   private void Page_Load(object sender, EventArgs e)
   {
   string name;
   name = Session["name"].ToString();
   }
5.  
   使用Cookie对象变量
   a.aspx的C#代码
   private void Button1_Click(object sender, System.EventArgs e)
   {
   HttpCookie cookie_name = new HttpCookie("name");
   cookie_name.Value = Label1.Text;
   Reponse.AppendCookie(cookie_name);
   Server.Transfer("b.aspx");
   }
   b.aspx中C#代码
   private void Page_Load(object sender, EventArgs e)
   {
   string name;
   name = Request.Cookie["name"].Value.ToString();
   }
6.  
   使用Server.Transfer方法
   a.aspx的C#代码
   public string Name
   {
   get{ return Label1.Text;}
   }
   private void Button1_Click(object sender, System.EventArgs e)
   {
   Server.Transfer("b.aspx");
   }
   b.aspx中C#代码
   private void Page_Load(object sender, EventArgs e)
   {
   a newWeb; //实例a窗体
   newWeb = (source)Context.Handler;
   string name;
   name = newWeb.Name;
   }
