折腾ado.net的行状态和行版本

class Program
    {
        static void Main(string[] args)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("ID", typeof(int));

            DataRow oneRow = dt.NewRow();
            oneRow[0] = 1;
            Console.WriteLine("新增加时的状态及版本:");
            output(oneRow);

            dt.Rows.Add(oneRow);
            Console.WriteLine("\n" + "增加到表中后的状态和版本:");
            output(oneRow);

            oneRow.BeginEdit();
            oneRow[0] = 5;
            Console.WriteLine("\n" + "开始编辑时的状态和版本:");
            output(oneRow);

            oneRow.EndEdit();
            Console.WriteLine("\n" + "结束编辑时的状态和版本:");
            output(oneRow);

            oneRow.AcceptChanges();
            Console.WriteLine("\n" + "接受更改后的状态和版本:");
            Console.WriteLine(oneRow[0]);
            output(oneRow);

            oneRow[0] = 6;
            Console.WriteLine("\n" + "再次编辑后的状态和版本");
            output(oneRow);

            dt.Rows[0].Delete();
            Console.WriteLine("\n" + "删除后的状态和版本:");
            output(oneRow);

            Console.ReadKey();
        }

        static void output(DataRow oneRow)
        {
            int[] version = new int[] { 256,512,1024,1536 };
            //打印行状态
            Console.WriteLine(oneRow.RowState);
            foreach (int i in version)
            {
                if (oneRow.HasVersion((DataRowVersion)i))
                {
                    //打印行版本名称及对应的值，用空格隔开
                    Console.Write(" " + (DataRowVersion)i + " " + oneRow[0, (DataRowVersion)i]);
                }
            }
            Console.WriteLine("\n-----------------------------------");
        }
    }

运行后的输出：
