『肆』 C语言 如何读取xml文件中的数据并存入一个结构体中

利用com、用xml的dll就可以了，不多说了，具体再不懂再问我把。我工作也有解析xml文件的 呵呵

『伍』 使用c#如何读取xml文件

XmlReader和XmlTextReader类定义在System.XML名字空间中。XmlTextReader类源于XmlReader类。XmlTextReader类可用来读取XML文档。此类的Read方法读取此文档，直到其节点结束。在这篇文章里，将演示如何使用XmlTextReader类来读取一个XML文档及输出数据到控制台。加入名字空间引用因为Xml类都定义在System.Xml名字空间当中，所以首先要做的是在工程里加入对System.Xml的引用。using System.Xml;打开一个XML文档XmlTextReader类的构造器打开一个XML文件。在这个例子里使用了一个名为xmltest.xml的文件，它保存在C:\temp目录当中。你可以下载此附件。// 打开一个 XML 文件 XmlTextReader reader = new XmlTextReader("C:\\temp\\xmltest.xml");读取数据XmlTextReader类的Read方法读取数据。while ( reader.Read() ){Console.WriteLine(reader.Name);}源代码：附件CS CodeXML文件namespace ReadXML { using System; using System.Xml; public static int Main(string[] args) { try { // 打开一个 XML 文件 XmlTextReader reader = new XmlTextReader("C:\\temp\\xmltest.xml"); while ( reader.Read() ) { Console.WriteLine(reader.Name); } } catch (Exception e) { Console.WriteLine ("Exception: {0}", e.ToString()); } return 0; } } }

『陆』 C#怎样读取XML文件中的指定值

两种方式： 1、使用xmldocument类加载这个xml，然后调用其成员函数查找你要的节点。 2、在vs中打开这个xml文件，在xml菜单中选择生成架构，将这个xsd保存为文件a.xsd，然后进入vs的命令行,进入a.xsd目录，调用“xsd.exe /c /n:MyNamespace a.xs

都是文本格式的,我想与读txt的区别在于两种文件的组织方式不一样而已,xml应该理解为受一种格式限制的文本文件,按照这些格式多做一些逻辑处理就行吧
