c# 读取XML文件的示例

如下XML文件：（算是一个属性值比较多的xml文件。。。读取该Xml算是我在公司实际的一个任务）

<?xml version="1.0" encoding="UTF-8"?>
<serverset>
<devset PrintNumber="1" ControlBarcode="" ControlEBarcode="" ControlPIX="" PrinterPort="0" isShowAreaName="0" PrinterPortData="127.0.0.1" SparePrinterNumber="1" SparePrinterNumber2="1" ProductionAreaName="1" PrintType="QT;1B;1K;1L;1M;" PrintDevType="0" logicalDpiW="" logicalDpiH="" Baudrate="4800" QZHEIGHT="1" QZwaittime="45" FILEwaittime="45" enablestwoway="1" CommandType="0"/>
<devset PrintNumber="2" ControlBarcode="" ControlEBarcode="" ControlPIX="" PrinterPort="0" isShowAreaName="0" PrinterPortData="127.0.0.211" SparePrinterNumber="1" SparePrinterNumber2="1" ProductionAreaName="" PrintType="" PrintDevType="0" logicalDpiW="" logicalDpiH="" Baudrate="4800" QZHEIGHT="1" QZwaittime="45" FILEwaittime="45" enablestwoway="0" CommandType="0"/>
<devset PrintNumber="3" ControlBarcode="" ControlEBarcode="" ControlPIX="" PrinterPort="0" isShowAreaName="0" PrinterPortData="127.0.0.3" SparePrinterNumber="1" SparePrinterNumber2="1" ProductionAreaName="" PrintType="" PrintDevType="0" logicalDpiW="" logicalDpiH="" Baudrate="4800" QZHEIGHT="1" QZwaittime="45" FILEwaittime="45" enablestwoway="0" CommandType="0"/>
<devset PrintNumber="4" ControlBarcode="" ControlEBarcode="" ControlPIX="" PrinterPort="3" isShowAreaName="0" PrinterPortData="USB2" SparePrinterNumber="1" SparePrinterNumber2="1" ProductionAreaName="" PrintType="" PrintDevType="2" logicalDpiW="" logicalDpiH="" Baudrate="4800" QZHEIGHT="1" QZwaittime="45" FILEwaittime="45" enablestwoway="1" CommandType="0"/>
<OrtherInfo printMode="1" PrintTimeConfig="5" FilterEmptyRows="0" PrintFilePath="D:/choice/ftp/tiktenPrint" BackFilePath="D:/choice/ftp/prnBakDir" readBOHPrintConfig="1" CondingFormat="0" isShowChangeBill="0" isRunUpgrade="0" SingleTurnSpaceTime="30" storeprnPath="127.0.0.1" FtpPort="" BCode="1020001" UploadVersionAddress="" UploadVersionPort="0"/>
</serverset>

创建一个类WriteXml用来封装读取Xml的和属性值方法：代码如下

class ReadXml
{
 /// <summary>
 /// 第一根节点的属性
 /// </summary>
 public string PrintNumber { get; set; }
 public string ControlBarcode { get; set; }
 public string ControlEBarcode { get; set; }
 public string ControlPIX { get; set; }
 public string PrinterPort { get; set; }
 public string isShowAreaName { get; set; }
 public string PrinterPortData { get; set; }
 public string SparePrinterNumber { get; set; }
 public string SparePrinterNumber2 { get; set; }
 public string ProductionAreaName { get; set; }
 public string PrintType { get; set; }
 public string PrintDevType { get; set; }
 public string logicalDpiW { get; set; }
 public string logicalDpiH { get; set; }
 public string Baudrate { get; set; }
 public string QZHEIGHT { get; set; }
 public string QZwaittime { get; set; }
 public string FILEwaittime { get; set; }
 public string enablestwoway { get; set; }
 public string CommandType { get; set; }

/// <summary>
 /// 第二根节点的属性
 /// </summary>

public string printMode { get; set; }
 public string PrintTimeConfig { get; set; }
 public string FilterEmptyRows { get; set; }
 public string PrintFilePath { get; set; }
 public string BackFilePath { get; set; }
 public string readBOHPrintConfig { get; set; }
 public string CondingFormat { get; set; }
 public string isShowChangeBill { get; set; }
 public string isRunUpgrade { get; set; }
 public string SingleTurnSpaceTime { get; set; }
 public string storeprnPath { get; set; }
 public string FtpPort { get; set; }
 public string BCode { get; set; }
 public string UploadVersionAddress { get; set; }
 public string UploadVersionPort { get; set; }

public void read()
 {
  XmlDocument xmlDoc = new XmlDocument();
  xmlDoc.Load(@"D:\Choic\PrintConfig.xml");//读取xml文件
  XmlNode xn = xmlDoc.SelectSingleNode("serverset");
  XmlNodeList xnlNL = xn.SelectNodes("devset");//得到根节点
  foreach (XmlNode xnl in xnlNL)//遍历devset
  {
   WriteAndRead wr = new WriteAndRead();
   XmlElement xe = (XmlElement)xnl;
   wr.PrintNumber = xe.GetAttribute("PrintNumber").ToString();
   wr.ControlBarcode = xe.GetAttribute("ControlBarcode").ToString();

   wr.logicalDpiW = xe.GetAttribute("logicalDpiW").ToString();
   wr.logicalDpiH = xe.GetAttribute("logicalDpiH").ToString();
   wr.Baudrate = xe.GetAttribute("Baudrate").ToString();
   wr.QZHEIGHT = xe.GetAttribute("QZHEIGHT").ToString();
   wr.QZwaittime = xe.GetAttribute("QZwaittime").ToString();
   wr.FILEwaittime = xe.GetAttribute("FILEwaittime").ToString();
   wr.enablestwoway = xe.GetAttribute("enablestwoway").ToString();
   wr.CommandType = xe.GetAttribute("CommandType").ToString();

Console.WriteLine("PrintNumber:" + wr.PrintNumber + "\tControlBarcode:" + wr.ControlBarcode + "\tControlEBarcode:" + wr.ControlEBarcode
    + "\tControlPIX:" + wr.ControlPIX + "\tPrinterPort:" + wr.PrinterPort + "\tisShowAreaName:" + wr.isShowAreaName + "\tPrinterPortData:"

    + "\tFILEwaittime:" + wr.FILEwaittime + "\tenablestwoway:" + wr.enablestwoway + "\tCommandType:" + wr.CommandType);
   Console.WriteLine();

}

XmlNodeList xnlNL1 = xn.SelectNodes("OrtherInfo");//得到第二个根节点
  foreach (XmlNode xnl in xnlNL1)//OrtherInfo
  {

WriteAndRead wr = new WriteAndRead();
   XmlElement xe = (XmlElement)xnl;
   wr.printMode = xe.GetAttribute("printMode").ToString();
   wr.PrintTimeConfig = xe.GetAttribute("PrintTimeConfig").ToString();
   wr.FilterEmptyRows = xe.GetAttribute("FilterEmptyRows").ToString();
   wr.PrintFilePath = xe.GetAttribute("PrintFilePath").ToString();
   wr.BackFilePath = xe.GetAttribute("BackFilePath").ToString();
   wr.readBOHPrintConfig = xe.GetAttribute("readBOHPrintConfig").ToString();
   wr.CondingFormat = xe.GetAttribute("CondingFormat").ToString();
   wr.isShowChangeBill = xe.GetAttribute("isShowChangeBill").ToString();
   wr.isRunUpgrade = xe.GetAttribute("isRunUpgrade").ToString();
   wr.SingleTurnSpaceTime = xe.GetAttribute("SingleTurnSpaceTime").ToString();
   wr.storeprnPath = xe.GetAttribute("storeprnPath").ToString();
   wr.FtpPort = xe.GetAttribute("FtpPort").ToString();
   wr.UploadVersionAddress = xe.GetAttribute("UploadVersionAddress").ToString();
   wr.UploadVersionPort = xe.GetAttribute("UploadVersionPort").ToString();
   Console.WriteLine("printMode:" + wr.printMode + "\tPrintTimeConfig:" + wr.PrintTimeConfig + "\tFilterEmptyRows:" + wr.FilterEmptyRows
    + "\tPrintFilePath:" + wr.PrintFilePath + "\tBackFilePath:" + wr.BackFilePath + "\treadBOHPrintConfig:" + wr.readBOHPrintConfig
    + "\tCondingFormat:" + wr.CondingFormat + "\tisShowChangeBill:" + wr.isShowChangeBill + "\tisRunUpgrade:" + wr.isRunUpgrade + "\tSingleTurnSpaceTime:" +
    wr.SingleTurnSpaceTime + "\tstoreprnPath:" + wr.storeprnPath + "\tFtpPort:" + wr.FtpPort + "\tUploadVersionAddress:" + wr.UploadVersionAddress + "\tUploadVersionPort:" + wr.UploadVersionPort);
  }
 }

在控制台上运行。。

class Program
{
 static void Main(string[] args)
 {
  ReadXml RX = new ReadeXml();
  RX.Read();
  Console.Read();
 }
}

运行结果如下：

好了，以上就是读取该XML文件以及实际运行结果图。。。。。。。

大牛们就当看个笑话啦！当然有哪里不对的地方或者可以改进的方法可以提出来。。。。对于一些没用读取过XML文件的程序猿们。。可供参考
