下面的linq求vb些写法

 static void Main(string[] args)

        {



            DataTable dtA = new DataTable();

            dtA.Columns.Add("id", typeof(int));

            dtA.Columns.Add("price", typeof(string));

            dtA.Rows.Add(1, "100");

            dtA.Rows.Add(2, "100");



            DataTable dtB = dtA.Clone();

            dtB.Rows.Add(1, "100");

            dtB.Rows.Add(3, "100");



            DataTable dtC = dtA.Clone();

            dtC.Columns.Add("price_excel");



            var leftData = from a in dtA.AsEnumerable()

                           join b in dtB.AsEnumerable()

                           on a.Field<int>("id") equals b.Field<int>("id") into g

                           from b in g.DefaultIfEmpty()

                           select new

                           {

                               id = a.Field<int>("id"),

                               price = a.Field<string>("price"),

                               price_excel = b == null ? "Null" : b.Field<string>("price")

                           };

            var rightData = from b in dtB.AsEnumerable()

                            where !dtA.AsEnumerable().Select(a => a.Field<int>("id")).Contains(b.Field<int>("id"))

                            select new

                            {

                                id = b.Field<int>("id"),

                                price = "Null",

                                price_excel = b.Field<string>("price")

                            };



            var fullJoinData = leftData.Union(rightData);

            fullJoinData.ToList().ForEach(q => dtC.Rows.Add(q.id, q.price, q.price_excel));

             Console.ReadLine();



        }

        

主要是
 on a.Field<int>("id") equals b.Field<int>("id") into g  这句 ，into g ，怎么都出错啊~
