It looks like you just want the distinct set of usernames... why not just use:

return _dataContext.PageStat.Select(u => u.UserName)
                            .Distinct()
                            .ToList();

If you really want to use grouping, you could do:

var q = from i in _dataContext.PageStat
        group i by i.UserName into ii
        select ii.Key;
return q.ToList();

You don't need all those anonymous types :)
