How to use the query as it looks like below
Here is my code
var SearchUser = (from u in db.Users
join l in db.LoggedInUsers on u.UserID equals l.UserID
where u.Username==txtSearch.Text
select u).SingleOrDefault();
litUsers.Text = "<div style='background-color:#B0C4DE;color:red'>"
+ "<a href=\"ChatWindow.aspx\">" + SearchUser.Username + "</a></div>";
Now I would like to add some querystring to the anchor tag? as I would like to add
session variable
Is it possible................

The query string is whatever comes after the "?" For example:
litUsers.Text = "<div style='background-color:#B0C4DE;color:red'>"
+ "<a href=\"ChatWindow.aspx?user=" + SearchUser.UserId
+ "\">" + SearchUser.Username + "</a></div>";
However, you need to be very careful when creating URLs - you get the equivalent of a SQL injection attack, but in HTML. In other words, you need to know that the UserId will not contain anything to escape in the URL. (You also need to be careful with SearchUser.Username in terms of HTML escaping.)
