.net中传值的几种方法

前面一段时间一直在做winform的程序,是关于PPT的二次开放,最近项目放下了,在等新的需求,突然有人问我WEB上几种传值的方法,晕死,居然没说全,郁闷,经验太少了,诶

所以今天把这些东西记下来

1.使用QueryString变量

+--------传递值
private void Button1_Click(object sender, System.EventArgs e)
{   
    string s_url;
    s_url = "xxxx.aspx?name=" + Label1.Text;   
    Response.Redirect(s_url);   
}   

+--------接受值
private void Page_Load(object sender, EventArgs e)   
{   
    Label2.Text = Request.QueryString["name"];   
}
==========================================
2.使用Application 对象变量

+--------传递值
private void Button1_Click(object sender, System.EventArgs e)   
{   
    Application["name"] = Label1.Text;   
    Server.Transfer("xxxx.aspx");   
}   

+--------接受值 
private void Page_Load(object sender, EventArgs e)   
{   
    string name;   
    Application.Lock();   
    name = Application["name"].ToString();   
    Application.UnLock();   
}
===========================================
3.使用Session变量

+--------传递值   
private void Button1_Click(object sender, System.EventArgs e)   
{   
    Session["name"] = Label.Text;   
}   

+--------接受值
private void Page_Load(object sender, EventArgs e)  
{   
    string name;   
    name = Session["name"].ToString();   
}
============================================
4.使用Cookie对象变量

+--------传递值    
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("xxx.aspx");   
}   

+--------接受值   
private void Page_Load(object sender, EventArgs e)   
{   
    string name;   
    name = Request.Cookie["name"].Value.ToString();   
}
=========================================
5.使用Server.Transfer方法
+--------传递值    
public string Name   
{   
get{ return Label1.Text;}   
}   
private void Button1_Click(object sender, System.EventArgs e)   
{   
Server.Transfer("xxxx.aspx");   
}   

+--------接受值  
private void Page_Load(object sender, EventArgs e)   
{   
    Passvalues newWeb; //实例传递值窗体   
    newWeb = (source)Context.Handler;   
    string name;   
    name = newWeb.Name;   
}
