您要如何处理会话和登录?您正在使用成员资格提供程序吗?

What are you trying to do with the session and login? Are you using a Membership Provider?

在登录页面中，您可以在检查用户提供正确的用户名和密码后创建会话.

In the login page you can create a session after checking the user has provided the correct username and pasword

Session["username"] = txt_username.Text;
Session["password"] = txt_password.Text;

之后，在每个页面中，您需要检查用户是否已登录，可以通过检查会话值来执行此操作.因此，在只有登录用户才能看到的每个页面加载事件中编写以下代码.

There after in every page you need to check if the user has been logged in or not , you can do this by checking the session values. So write the following code in every page load event which only logged in users should see.

if(Session["username"] == null || Session["password"]== null)
{
Response.Redirect("Login.aspx");
}
else
{
// You can write your desired code here

}

这只是一个lgin过程的小例子.您应该实施适当的方法来避免诸如SQL注入之类的安全漏洞.

希望这对您有所帮助.

如有任何疑问，请通知我.
