If you use TypeDataSet and the table name=tableName then by using linq you can do it easily as following..

        var query = from row in tableName.AsEnumerable()
                    group row by row.User into Group                        
                    select new
                    {
                        User = Group.Key,
                        SvcSum = Group.Sum(r => r.svc),
                        VssSum = Group.Sum(r => r.vss)
                    };

        foreach (var grp in query)
        {
            Console.WriteLine("{0}\t{1}\t{2}", grp.User, grp.SvcSum, grp.VssSum);
        }

I have test it by creating table and project. i think this will be helpful for you.
