Declare, create, create the root node, add the sub-node of Books, and finally save the document (if the file already exists, update it; if not, create the file), friends who don’t know how can learn more

The code is as follows:

protected void Button1_Click(object sender, EventArgs e)//创建xml 
{ 
//声明 
XmlDocument x = new XmlDocument(); 
//创建 
XmlDeclaration xd = x.CreateXmlDeclaration("1.0", "GB2312", null); 
x.AppendChild(xd); 
//创建根节点 
XmlElement element = x.CreateElement("Books"); 
x.AppendChild(element); 
//添加Books的子节点 
XmlNode book = x.CreateElement("Book"); 
//给Book添加元素 
XmlElement bookname = x.CreateElement("书名"); 
bookname.InnerText = "三国"; 
//逐级添加到节点上 
book.AppendChild(bookname); 
element.AppendChild(book); 
x.AppendChild(element); 
//保存文档(如果已经存在该文件,则更新之;如果没有,则创建该文件) 
x.Save(@"F:/Books.xml"); 
}
