In C# you can define a session variable like this:

在C#中,您可以像这样定义会话变量:

Session["userame"]= txtusername.Text;

where txtusername is a text box. In another page you can call it as:

其中txtusername是一个文本框。在另一个页面中,您可以将其称为:

string usrname = Session["username"].ToString();

To check whether a user is logged in or not, in a particular page; you'll have to check if this session is empty or not. If the session is null then redirect the user to login page else he/she can view the page. Same logic applies to all the pages where you want to implement the session validation. Sample (on Page_Load event):

在特定页面中检查用户是否已登录;你必须检查这个会话是否为空。如果会话为null,则将用户重定向到登录页面,否则他/她可以查看该页面。相同的逻辑适用于要实现会话验证的所有页面。示例(在Page_Load事件上):

if (Session["username"] == null)
   Response.Redirect ("Login.aspx");

The question is broad answer, in Simply you can follow like this

问题是广泛的答案,简单地说,你可以像这样

Create database, user table in sql server or any database of your choice

在sql server或您选择的任何数据库中创建数据库,用户表

Create the login form with userid and password

使用用户标识和密码创建登录表单

Check them with database for user availability

使用数据库检查它们是否可用

If User exist and password matches create a session, like Session.Add ("Userid", txtUserid.Text);

如果用户存在且密码匹配则创建会话,如Session.Add(“Userid”,txtUserid.Text);

In other pages (restricted pages where only registered users allowed) write this code in every page load event

在其他页面(仅允许注册用户的受限页面)中,在每个页面加载事件中编写此代码

if (Session["Userid"] == null) Response.Redirect ("Login.aspx");

if(Session [“Userid”] == null)Response.Redirect(“Login.aspx”);

Session["login_user"] = "[username]";
string username = Session["login_user"].ToString().Trim();
