Sharepoint 2010. Resource Calendar - add new item with resource

[fxrobot]

Hi, I'm having some difficult adding a resource to when adding a new item using C#. I opened a new Calendar with Resource Reservation option enabled. I also added "Room1" to the resources list in the site. part of my code :

       using (SPSite site = new SPSite("http://sps/mysite"))
        {
            using (SPWeb web = site.OpenWeb())
            {
                SPList list = web.Lists\["Rooms"\];
                if (list != null)
                {
                    SPListItem item     = list.Items.Add();
                    item\["Title"\]       = "New Resource sched..";
                    item\["Description"\] = "check resource sched..";
                    item\["Resources"\]   = "??"; //<- what to put here??? 
                    item\["Start Time"\]  = DateTime.Now.AddDays(2);
                    item\["End Time"\]    = DateTime.Now.AddDays(3);
                    item\["Category"\]    = "Business";
                    item\["fAllDayEvent"\]= false;

                    item.Update();
                }
               else
                {
                   System.Console.WriteLine("List does not exists");
                   System.Console.ReadLine();
                }
            }

        }

what do I need to write in : item["Resources"] ? writing "=Room1" doesn't work and I probably need to link the "Room1" item in the resources list. appreciate your help////

you can try like this SPList ResourcesList = web.Lists["Resources"]; SPQuery query= '..write the query to get the Room1 resources item..'; SPListItem room= ResourcesList.GetItems(query)[0]; .... item[Resources]= new SPFieldLookupValue(Convert.ToInt32(room["ID"]), "Room1");
