Grab Id from asp.net and use in C# code -

i'm trying larn c# , asp.net webforms , working on application similar how reddit or facebook might function. users have ability create accounts, send , take friend requests, leave wall posts etc.

i have implemented ability send friend request, stuck on part user can take request. here c#:

using (database.datamodeldatacontext db = new database.datamodeldatacontext()) { //guid requesterid = new guid(request.querystring["id"]); crank.database.friendship requestaccept = new database.friendship { id = guid.newguid(), usera = base.userid, userb = }; db.friendships.insertonsubmit(requestaccept); db.submitchanges(); }

so can see, usera added database logged-in users id. can't figure out how info userb or person original friend request sent from. i'm assuming can somehow grab code in asp.net.

so id stored in commandargument. used code:

guid userrequested = guid.parse(e.commandargument.tostring()); userb = userrequested

c# asp.net sql linq
