Hi

   I have below code . I want to clear all Session Values. Is the below code correct.

Secondly how we can check that all Session variables are destroyed.

try
        {
            if (Session["InvoiceNo"] != null)
            {
                lblName.Text = Session["CustomerName"].ToString();
                lblAddress.Text = Session["CustomerAddress"].ToString();
                lblInvoiceNo.Text = Session["InvoiceNo"].ToString();
            }
        }
        catch (Exception ex)
        {

        }
        finally
        {
            Session.Abandon();
        }

Thanks

Hi,

Use Session.Clear(); before Session.Abandon();

Not directly related but I never use an empty catch block (you want to fix programming errors rather than to just ignore them).

Hello jssivalik,

According to your requirements you have to use . 

Reference https://stackoverflow.com/questions/5330268/how-to-kill-a-session-or-session-id-asp-net-c/5330288#5330288 

The Abandon method should work (MSDN):

Session.Abandon();

If you want to remove a specific item from the session use (MSDN):

Session.Remove("YourItem");

EDIT: If you just want to clear a value you can do:

Session["YourItem"] = null;

If you want to clear all keys do:

Session.Clear();

And how it works when session is destroyed/terminated

I hope this will help you

Thank you
