I have gone through this link : http://msdn.microsoft.com/en-us/library/office/ee538244(v=office.14).aspx

But through this I am only able to get user details which are in groups. I am not able to get users other then groups. I need all means all users of the site in client object model.

Please help. Thank You.

You can query SiteUserInfoList to get all users in a site.

ClientContext clientContext = new ClientContext("http://your site/");
Web web = clientContext.Web;
List siteUserInfoList = web.SiteUserInfoList;
CamlQuery query = new CamlQuery();
query.ViewXml = "";
IEnumerable<ListItem> itemColl = clientContext.LoadQuery(siteUserInfoList.GetItems(query));
foreach (var item in itemColl)
    Console.WriteLine("ID:{0}  Email:{1} Title:{2}", item.Id, item["EMail"], item["Title"]);
  • Yeah it worked for me... thanx mate

You can try following:

    Web web = context.Web;

List siteUserInfoList = web.SiteUserInfoList;  



This way you can get all users.
