//obtain cookie, if its there
HttpCookie cookie = Request.Cookies["MyCookie"] as HttpCookie ;

//cookie needs to be added first time?
if (cookie == null)
{
cookie = new HttpCookie("MyCookie");
}

//add value to existing (or new cookie)
cookie.Values.Add("Country", "India");
//append one more value to same cookie
cookie.Values.Add("City", "New Delhi");

//update (or add) cookie
Response.Cookies.Add(cookie);

You cannot directly modify a cookie. Instead, changing a cookie consists of creating a new cookie with new values and then sending the cookie to the browser to overwrite the old version on the client.

So you can use the value as
String str= Request.Cookies["Key1"].ToSting();str= str+ " more value"; Response.Cookies["Key1"].Value = str;

Smart Lucky,

You're not actually appending to the value associated with the key of "asp" but changing the value associated with the key of "Val1".

Is that what you intended?

Response.Cookies writes a cookie and Request.Cookies is used to read a cookie

So use
Response.Cookies["hidaya"]["Val1"] = value + " " + "Sql Server , Share Point Crystal Report";

1. HttpCookie cookie = Request.Cookies["Something"]; 2. string prevValue = cookie["Data"]; 3.cookie["Data"]= prevValue + "; additional data"; 4. Response.Cookies.Add(cookie);

Using the cookie you created in your other thread:

string value = Request.Cookies["hidaya"].Values["Val1"];
Request.Cookies["hidaya"].Values["Val1"] = value + " " + "whatever";

1. Get cookie from request
2. Extract desired value from it
3. Calculate new value which is concantenation of previous value and new part
4. Set the same cookie with updated value.
