net页面传值

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"];
}
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();
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();
}
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();
}
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();
}
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;
}
