asp.net - how to use session variable in asp using c#

Question

how we create session in login page in asp .net with c# give me full example......

Answer 1

Assuming that your code is in the page (either inline or in the code behind) you can just use...

DataType someValue = (DataType)Session["SessionVariableNameHere"]; //Getter
Session["SessionVariableNameHere"] = someNewValue; //Setter

Obviously you'll need to name your session variable properly, and cast to the appropriate data type when you get it back out of the session.

EDIT - A Full Example

protected void Login1_LoggedIn(object sender, EventArgs e)
{
    Session["LoginTime"] = DateTime.Now;
}

and later in a page load...

protected void Page_Load(object sender, EventArgs e)
{
    Literal1.Text = "Last Online: " + ((DateTime)Session["LoginTime"]).ToString("yyyy-MM-dd");
}
