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 void read()

   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;

    console.writeline("printnumber:" + wr.printnumber + "\tcontrolbarcode:" + wr.controlbarcode + "\tcontrolebarcode:" + wr.controlebarcode

    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();

   } 
  }

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
