Context传值
通过Context传值，在传送页面之前，将需要传递到其他页面的值存在Context中。

protected void btn1_ServerClick(object sender, EventArgs e)
{
Context.Items["value"] = txt1.Value;
Server.Transfer("DestinationPage3.aspx");

string aa = sourcePage.Value;

Cookie传值
传送页面代码
View Code
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Cookie</title>
</head>
<body>
<form id="form1" runat="server">

protected void btn1_ServerClick(object sender, EventArgs e)

string aa = txt1.Value;
HttpCookie cookie = new HttpCookie("MyCookie", aa);
Response.Cookies.Add(cookie);
string url = "DestinationPage8.aspx";
Response.Redirect(url, false);
}
接收页面代码
View Code
protected void Page_Load(object sender, EventArgs e)
{
HttpCookie myCookie = Request.Cookies["MyCookie"];
txt1.Value = myCookie.Value;
}
Session传值
通过Session取值，在一个页面中赋值，在其他页面中共享。为避免造成Session值的混乱无序，应尽量少用Session传非公共的变量。Session比较适合用来保存一些公共变量。
传送页面代码
View Code
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Session传值</title>
</head>
<body>
<form runat="server">
<input type="text" id="txt1" runat="server" />
<input type="button" id="btn1" value="提交" runat="server" onserverclick="btn1_ServerClick" />
</form>
</body>
</html>
protected void btn1_ServerClick(object sender, EventArgs e)
{
Session["value"] = txt1.Value;
Response.Redirect("DestinationPage2.aspx");
}
接收页面代码
View Code
protected void Page_Load(object sender, EventArgs e)
{
txt1.Value = Session["value"].ToString();
}
Application传值
此种方法不常使用，因为Application在一个应用程序域范围共享，所有用户可以改变及设置其值，故只应用于计数器等需要全局变量的地方。
