C#在WINForm程序中创建XML文件

<?xml version="1.0" encoding="gb2312"?><FilesInformation> <version>1.0.1818.42821</version> <description>说明</description> <FileItem  FileName="name" FileVersion="sdf" FileLength="sdf" FileCreationTime="sd" /></FilesInformation>

string path = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;

获取和设置包含该应用程序的目录的名称

File.Exists(path + XmlFileName)

File.Exists是判断文件是否存在，传入参数为路径+文件名

XmlDocument xmlDoc = new XmlDocument();

这一句是创建一个XmlDocument对象

XmlDeclaration xmlSM = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);

这一句是添加xml文件头的声明

xmlDoc.AppendChild(xmlSM);

这一句是将创建的XmlDocument对象追加到xml文件声明后面

XmlElement DeviceTree = xmlDoc.CreateElement("DeviceTree");

这一句为创建一个标签名为DeviceTree的节点

DeviceTree.SetAttribute("name", "设备树");

这一句设置节点的name属性为设备树

xmlDoc.AppendChild(DeviceTree);

这一句是将创建的节点添加到开始创建的XmlDocument对象中

xmlDoc.Save(path + XmlFileName);

最后是保存创建好的xml文件

方法1：

private void button1_Click(object sender, EventArgs e) { XmlDocument xmlDoc = new XmlDocument(); //建立Xml的定义声明 XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "utf-8", null); xmlDoc.AppendChild(dec); //创建根节点 XmlElement root = xmlDoc.CreateElement("FilesInformation"); xmlDoc.AppendChild(root); XmlElement version = xmlDoc.CreateElement("version"); version.InnerText = "1.0.1818.42821"; root.AppendChild(version); XmlElement description = xmlDoc.CreateElement("description"); description.InnerText = "说明"; root.AppendChild(description); XmlElement fileItem = xmlDoc.CreateElement("FileItem"); fileItem.SetAttribute("FileName", "name"); fileItem.SetAttribute("FileVersion", "xx"); fileItem.SetAttribute("FileLength", "xxx"); fileItem.SetAttribute("FileCreationTime", "xxxx"); root.AppendChild(fileItem); xmlDoc.Save("test.xml");  }

方法2：

 XmlDocument xmldoc = new XmlDocument(); XmlText xmltext;
 //声明 XmlNode xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", ""); xmlnode.InnerText += " encoding=\"GB2312\""; xmldoc.AppendChild(xmlnode);
 //添加根节点 XmlElement xmlelementroot = xmldoc.CreateElement("", "Config", ""); //根节点包含节点文本时会造成XML文档结构的混乱 //xmltext = xmldoc.CreateTextNode("配置信息"); //xmlelementroot.AppendChild(xmltext); xmldoc.AppendChild(xmlelementroot);
 //添加一个元素 XmlElement xmlelement1 = xmldoc.CreateElement("", "DTL", ""); xmltext = xmldoc.CreateTextNode("2010-10-25"); xmlelement1.AppendChild(xmltext); xmldoc.ChildNodes.Item(1).AppendChild(xmlelement1);
 //添加另一个元素 XmlElement xmlelement2 = xmldoc.CreateElement("", "DTF", ""); xmltext = xmldoc.CreateTextNode("2011-02-10"); xmlelement2.AppendChild(xmltext); xmldoc.ChildNodes.Item(1).AppendChild(xmlelement2);
 //保存                xmldoc.Save(Environment.CurrentDirectory+"\\111.xml");

方法3：

XmlTextWriter xmlwriter = new XmlTextWriter(getPath(), Encoding.Default); xmlwriter.Formatting = Formatting.Indented; xmlwriter.Indentation = 4;
 xmlwriter.WriteStartDocument(); xmlwriter.WriteStartElement("", "Config", "");
 xmlwriter.WriteStartElement("", "DTL", ""); xmlwriter.WriteString("2010-10-25"); xmlwriter.WriteEndElement();
 xmlwriter.WriteStartElement("", "DTF", ""); xmlwriter.WriteString("2011-02-10"); xmlwriter.WriteEndElement();
 xmlwriter.WriteEndElement(); xmlwriter.WriteEndDocument();
 xmlwriter.Flush(); xmlwriter.Close();
