Save form data in session

Question

I created an access form for my administrative area, using a tutorial by Microsoft.

Now I need to retrieve the login that he typed to enter and show it on an administration page, and also to make future queries to the database.

How can I do that? I was told to save the login and password in one Session and then retrieve it on the other page, but I have no idea how to implement.

Answer 1

Sessions are ways to store data that will be deleted when a given event occurs (in the default behavior of ASP.NET, when 20 minutes have passed since the user’s last action, or when the browser window is closed).

Creating a Session couldn’t be easier:

Session["NomeDaSession"] = "ValorDaSession";

Check the value of it also:

// Primeiro verificamos se a session existe
if (Session["NomeDaSession"] != null)
    // Operações pertinentes

However, in addition to answering your question, it is up to me to recommend the use of a more recent technology, if you are working on something new. I know that, for legacy, there is usually no way. Instead of Web Forms, try to use ASP.NET MVC where relevant.

When you’re using FormsAuthentication you will be able to recover the logged in user in this way:

string username = "";
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
    username = HttpContext.Current.User.Identity.Name;
}
