How to create a cookie and how to provide value to it?

To create a cookie,

HttpCookie CookieName = new HttpCookie("Users");

To set values for the cookie,

CookieName.Values.Add("Products", "ITFunda");

Suppose you want to add the cookie to the cookie collection, then

Response.Cookies.Add(CookieName);

To get the value stored in the cookie

Response.Write(CookieName.Value.ToString());

Suppose you want to retrive the specific cookie, then

Response.Write(CookieName["Products"].ToString());
