Подскажите пожалуйста как это реализовать если я использую Entity Framework 4.0
http://www.codeproject.com/KB/web-se...sroleauth.aspx
в частости интересует вот этот вот кусок кода
Код:
private void btnLogin_Click(Object sender, EventArgs e)
{
// Initialize FormsAuthentication, for what it's worth
FormsAuthentication.Initialize();
// Create our connection and command objects
SqlConnection conn =
new SqlConnection("Data Source=localhost;Initial Catalog=web;");
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "SELECT roles FROM web WHERE username=@username " +
"AND password=@password";
// Fill our parameters
cmd.Parameters.Add("@username", SqlDbType.NVarChar, 64).Value =
Username.Value;
cmd.Parameters.Add("@password", SqlDbType.NVarChar, 128).Value =
FormsAuthentication.HashPasswordForStoringInConfigFile(
Password.Value, "md5"); // Or "sha1"
// Execute the command
conn.Open();
SqlDataReader reader = cmd.ExecuteReader();
if (reader.Read())
{
// Create a new ticket used for authentication
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, // Ticket version
Username.Value, // Username associated with ticket
DateTime.Now, // Date/time issued
DateTime.Now.AddMinutes(30), // Date/time to expire
true, // "true" for a persistent user cookie
reader.GetString(0), // User-data, in this case the roles
FormsAuthentication.FormsCookiePath);// Path cookie valid for
// Encrypt the cookie using the machine key for secure transport
string hash = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(
FormsAuthentication.FormsCookieName, // Name of auth cookie
hash); // Hashed ticket
// Set the cookie's expiration time to the tickets expiration time
if (ticket.IsPersistent) cookie.Expires = ticket.Expiration;
// Add the cookie to the list for outgoing response
Response.Cookies.Add(cookie);
// Redirect to requested URL, or homepage if no previous page
// requested
string returnUrl = Request.QueryString["ReturnUrl"];
if (returnUrl == null) returnUrl = "/";
// Don't call FormsAuthentication.RedirectFromLoginPage since it
// could
// replace the authentication ticket (cookie) we just added
Response.Redirect(returnUrl);
}
else
{
// Never tell the user if just the username is password is incorrect.
// That just gives them a place to start, once they've found one or
// the other is correct!
ErrorLabel = "Username / password incorrect. Please try again.";
ErrorLabel.Visible = true;
}
reader.Close();
conn.Close();
}
как бы это мне архитектуру не порушить?
