C#项目开发全程实录中的 方法类定义如这一段
 string str_Add = "insert into tb_JhGoodsInfo values( ";
                str_Add += "'" + tbGood.strGoodsID + "','" + tbGood.strEmpId + "','" + tbGood.strJhCompName + "',";
                str_Add += "'" + tbGood.strDepotName + "','" + tbGood.strGoodsName + "','" + tbGood.strGoodsNum + "',";
                str_Add += "'" + tbGood.strGoodsUnit + "'," + tbGood.deGoodsJhPrice + " ," + tbGood.deGoodsSellPrice + " ,";
                str_Add += "" + tbGood.deGoodsNeedPrice + "," + tbGood.deGoodsNoPrice + ",'" + tbGood.strGoodsRemark + "',";
                str_Add += "'" + tbGood.DaGoodTime + "'," + tbGood.Falg + ")";
                getSqlConnection getConnection = new getSqlConnection();
                conn = getConnection.GetCon();
                cmd = new SqlCommand(str_Add, conn);

   每执行到      intFalg = cmd.ExecuteNonQuery();就弹出说 第一行附近有语法错误。。错在哪啊 搞了好久没弄出来
                conn.Dispose();
                return intFalg;
