hi,
I;m using a Dictioanry collection to store FirstName using SessionID as key. then i store it in a session object. I need to extract the first Name from the user's home page.

 

Button_Click()
{
   Dictionary firstNames = new Dictionary(stirng, string)();
   Session.add("FirstNames", null);
   DataTable dt = obj.Authenticate(user, pass);
 
   string strSessionID = Session.SessionID;
 
   foreach(DataRow row in dt.Rows)
   {
      firstNames.Add(row, strSessionID);      
   }
 
   Session["FirstNames"] = firstNames;
 
}

How do i search the FirstName based on the sessionID from the user's home page? (this is an issue when there are more than one user logged in to the server)
TY

Problem is how do i pass the sessionID to the user's home page

Hi Friend,

Here is Solution ..For Finding Key From Value Write a Function Like below

public string FindKeyByValue(Dictionary<string, string> myDic, string ValueWhichYouWantoUsAsKey )

    {



        foreach (string key in myDic.Keys)

        {

            if (myDic[key] == ValueWhichYouWantoUsAsKey)

            {

                return key;

            }

        }

        return null;

    }

Please use sessionId as key:
like Dic.Add(sessionID, row);

Then you can retrieve value like this:

Dic[SessionID];

Thank you.
