要将数据从一页传输到另一页或通过asp.net中的整个应用程序传输，有不同的方法.

1)使用会话
2)使用Cookies
3)使用QueryString


1)使用会话 SessionInfo [ ^ ]
您可以将简单数据和复杂数据存储到会话对象，会话将维护服务器端.

For transferring data from one page to another page or through out entire application in asp.net, there are different different way.

1) Using Sessions
2) Using Cookies
3) Using QueryString


1) Using Session SessionInfo[^]
you can store simple as well as Complex data to session object, session will maintain server side.

//Declaring and Storing value to session variable
//Sysntax
Session["SESSIONNAME"] = value;
e.g.
//Use of Session
//Setting Value to Session variable
Session["USER_NAME"] = "Tejas Vaishnav";

//Accessing Value from Session variable
string _userName = Session["USER_NAME"].toString();

2)使用Cookie CookieInfo [ ^ ]
Cookie是用于存储数据客户端的小型文本文件.

2) Using Cookie CookieInfo[^]
Cookie is a small text file used to store data client side.

//Syntax
//Creating and storing value to cookie
HttpCookie _cookie = new HttpCookie("COOKIE NAME");
_cookie["COOKIE NAME"] = "Value";
Response.Cookies.Add(_cookie);

//Retrieves value from Cookie
HttpCookie _cookieValue = Request.Cookies["COOKIE NAME"];
string _name =  _cookieValue["COOKIE NAME"].toString();


e.g.
//Use
HttpCookie _cookie = new HttpCookie("USER_NAME");
_cookie["USER_NAME"] = "Tejas Vaishnav";
Response.Cookies.Add(_cookie);

//Accessing value from cookies
HttpCookie _cookieValue = Request.Cookies["USER_NAME"];
string _userName =  _cookieValue["USER_NAME"].toString();

3)使用QueryString QueryStringInfo [

3) Using QueryString QueryStringInfo[^]
Query string is a collection of Key and value pair passed through your page URL.

//Declaration syntax
Response.Redirect("~/Default.aspx?name=tejas&lastName=vaishnav");

//Example of Query string
http://www.xyz.com/Default.aspx?name=tejas&lastName=vaishnav

//Accessing data from Query string
string _name = Request.QueryString["Name"].toString();
string _lastName = Request.QueryString["LastName"].toString();

这些方法可以将数据从一页传递到另一页.

these all the way you can pass data from one page to another page.

最简单的方法是实现成员身份:

The easiest way is to implement membership: Introduction to Membership[^] - the link will show you how, and also how to use it when they are signed in.
