dbo 读取EXCEL 怎么获取EXCEL 行号？

[mycodeis0000]

 using (OleDbConnection Conn = new OleDbConnection(ConnString))
                {
                    OleDbCommand Comm = new OleDbCommand();
                    Comm.Connection = Conn;
                    OleDbDataAdapter Adapter = new OleDbDataAdapter();
                    Conn.Open();
                    //动态获取excel内的sheet
                    DataTable sheetNameTable = Conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "Table" });
                    string TableName = sheetNameTable.Rows[0]["TABLE_NAME"].ToString();

                    Comm.CommandText = "select * from [" + TableName + "]";


                    Adapter.SelectCommand = Comm;
                    dtImport = new DataTable("BFCliChkMonImptDetl");
                    Adapter.Fill(dtImport);

                    if (Conn.State != ConnectionState.Closed)
                    {
                        Conn.Close();
                    }
                }
