XML——读与写

XML写入

private static void writeXml()
{
    using (XmlTextWriter xml = new XmlTextWriter(@"C:UsersDellDesktopoot.xml", Encoding.UTF8))
    {
        try
        {
            xml.Formatting = Formatting.Indented;
            xml.WriteStartDocument(true);
            xml.WriteComment("学校的描述");
            xml.WriteStartElement("school");
            xml.WriteComment("学生的描述");
            xml.WriteElementString("student", "学生");
            xml.WriteComment("老师的描述");
            xml.WriteElementString("teacher", "老师");
            xml.WriteComment("校长的描述");
            xml.WriteElementString("principal", "校长");
            xml.WriteComment("编号的描述");
            xml.WriteElementString("number", "123456");
            xml.WriteComment("时间的描述");
            xml.WriteElementString("Time", DateTime.Now.ToString());
            xml.WriteEndElement();
            xml.WriteEndDocument();
        }
        catch (Exception ee) { Console.WriteLine(ee); }
        finally { xml.Flush(); xml.Close(); }
    }
}

XML读取

private static string student { get; set; }
private static string teacher { get; set; }
private static string principal { get; set; }
private static int number { get; set; }
private static DateTime Time { get; set; }
private static void readXml()
{
    string _xml_path = @"C:UsersDellDesktopoot.xml";
    if (!File.Exists(_xml_path)) return;
    using (XmlTextReader xml = new XmlTextReader(_xml_path))
    {
        try
        {
            while (xml.Read())
            {
                if (xml.NodeType == XmlNodeType.EndElement && xml.Name == "school") break;
                if (xml.NodeType != XmlNodeType.Element) continue;
                switch (xml.Name)
                {
                    case "student": student = xml.ReadString(); break;
                    case "teacher": teacher = xml.ReadString(); break;
                    case "principal": principal = xml.ReadString(); break;
                    case "number": number = Convert.ToInt32(xml.ReadString()); break;
                    case "Time": Time = Convert.ToDateTime(xml.ReadString()); break;
                }
            }
        }
        catch (Exception ee) { Console.WriteLine(ee); }
        finally { xml.Close(); }
    }
}

控制台调用

static void Main(string[] args)
{
    //writeXml();
    //Console.WriteLine("完成");
    readXml();
    Console.WriteLine(student + teacher + principal + number + Time);
    Console.ReadKey();
}

结果：
