Session state in ASP.NET C#

Dear viewer's in this tutorial I will explain about session state in ASP.NET’ C #. Session allows to store any type of data in memory on ther server.Session Information is more Proted and reliable for security purpose .Session information is not transferred to the client and it can be identified uniquely for individual client.Best example of session is shopping cart. The most important thing to remember that session value is always move one page to another page as necessary. In this tutorial I have taken two pages one for inputting session value and another for displaying session value. When user click user Log In the User Name and Password will be stored to the sessions and displayed another page.
