生成和读取XML文件的方法-创新互联

                       string shen = "";
                        string unit = "";
                        string m = dt.Rows[k]["Height"].ToString();
                        Regex reg = new Regex(@"[^0-9,^.]+");
                        Regex reg2 = new Regex(@"[^A-Za-z]+");
                        shen = reg.Replace(m, "");
                        unit = reg2.Replace(m, "");
                        sr.WriteLine("" + unit + "");
                        sr.WriteLine("" + shen + "");
                        sr.WriteLine("");
                    }
                }
            }

           //写文件尾部内容
            sr.WriteLine("");
            sr.WriteLine("");
            sr.Close();
        }

读取xml文件的代码：

///

           XmlNode xn = myDoc.SelectSingleNode("//VoteInfo[ID='1']");//读取数据源

           XmlNodeList xnl = xn.SelectNodes("Item");

           for (int i = 0; i < xnl.Count; i++)
            {
                XmlNode xn0 = xnl.Item(i);
                ydata += xn0.SelectSingleNode("Count").InnerText + ",";
                xdata += "\'" + xn0.SelectSingleNode("Title").InnerText + "\'" + ",";
                unit = xn0.SelectSingleNode("Unit").InnerText;
            }
            ydata = ydata.Remove(ydata.Length - 1, 1);
            xdata = xdata.Remove(xdata.Length - 1, 1);
        }
