ASPNET頁面傳值的幾種常用方式

1：Querystring：所傳值會顯示在浏覽器位址欄，是以适合傳少量且無安全要求的值

傳值頁面代碼：

string QueryString = "WebForm1.aspx?name=" + TextBox1.Text + "&pwd=" + TextBox2.Text+"&[email protected]";

Response.Redirect(QueryString);

  lblQueryString.Text = "QueryString:" + Request.QueryString["name"] + Request.QueryString["pwd"] + Request.QueryString["email"];

2：Session：針對具體使用者。資料過多時對伺服器造成壓力，Session.Clear();

Session["name"] = TextBox1.Text;

Session["pwd"] = TextBox2.Text;

Session["username"] = "admin";

Response.Redirect("WebForm1.aspx");

lblSession.Text = "session:" + Session["name"].ToString() + Session["pwd"].ToString() + Session["username"].ToString();

 3：Application：所有頁面都能通路，針對站點所有浏覽使用者

Application["name"] = TextBox1.Text;

Application["pwd"] = TextBox2.Text;

Application["sex"] = "男";

Response.Redirect("WebForm1.aspx");

  lblapplication.Text = "application:" + Application["name"]+ Application["pwd"]+ Application["sex"];

4：Cookie：關閉浏覽器儲存在用戶端

HttpCookie name = new HttpCookie("name");

name.Value = TextBox1.Text;

Response.Cookies.Add(name);

Response.Redirect("WebForm1.aspx");

lblcookie.Text =Request.Cookies["name"].Value;

5：Server.Transfer
