關於網頁之間的傳值

對於兩個頁面之間的傳值，今天總結一下：

1、Url重寫

Send.aspx:

Request.Redirect("Receive.aspx?username=小譚");

 

Receive.aspx:

string username = Request.QueryString["username"];

 

2、Form指定Method路徑

Send.aspx:

<form id="form1" runat="server" action="receive.aspx" method=post>

<asp:Button ID="btnTest" runat="server" OnClick="btnTest_Click" Text="Form傳值"/>

</form>

Receive.aspx:

string username = Request.Form["username"];

 

3、Cookies

Send.aspx:

HttpCookie cookie = new HttpCookie("username", "小譚");
Response.Cookies.Add(cookie);

Response.Redirect("Receive.aspx");

 

Receive.aspx：

string username = Request.Cookies["username"].Value;

4、Session、Application（將其中的Session替換即可）

Send.aspx:

Session["username"] = "小譚";

Receive.aspx:

string username = Session["username"];

 

5、Transer

Send.aspx:

 public string UserName
        {
            get {
                return "小譚";
            }
        }

Server.Transfer("Receive.aspx");

Receive.aspx：

Send send = (Send)Context.Handler;

string username = send.UserName;
