读取 XML 并填充列表
读取 XML 并填充列表
这个问题已经有了答案::
我有一个学生类，并且想要读取一个包含学生信息的XML文件并将信息放入列表中。
我的代码：
internal class Student
{
private string name = null;
private string age = null;
private string age = null;
public string Name
{
get { return name; }
set { name = value; }
}
public string Age
{
get { return age; }
set { age = value; }
}
}
我正在读取以下XML文件：
Name_1 1 Name_2 2 Name_3 3
这是我的主方法：
string filePath = "C:\\StudentInfo.xml";
XmlDocument doc = new XmlDocument();
doc.Load(filePath);
StreamReader reader = new StreamReader(filePath);
string line = "";
string xmlValue = null;
Student stu = new Student();
List stuList = new List();
while ((line = reader.ReadLine()) != null)
{
if (line.Contains(""))
{
XmlNodeList elemList = doc.GetElementsByTagName("NAME");
for (int i = 0; i < elemList.Count; i++)
{
xmlValue = elemList[i].InnerXml;
stu.Name = xmlValue;
Console.WriteLine(xmlValue);
}
}
stuList.add(stu);
}
我需要读取XML并将stu对象放入stuList中。
我该怎么做？
更新：我使用了Pradip Nadar提到的LINQ语句
XDocument xdoc = XDocument.Load("C:\\StudentInfo.xml");
List lv1s = (from lv1 in xdoc.Descendants("STUDENT")
select new Student
{
Name = lv1.Element("NAME").Value,
Age = lv1.Element("AGE").Value
}).ToList();
foreach (Student s in lv1s)
{
Console.WriteLine(s.Name);
Console.WriteLine(s.Age);
}

有两个不同的类：学生类和学生容器类。您只需调用StudentContainer类的方法即可，例如保存、加载或从文本加载。
using System.Xml;
using System.Xml.Serialization;
public class Student
{
[XmlElement("NAME")]
public string Name;
[XmlElement("AGE")]
public int Age;
}
using System.Collections.Generic;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
[XmlRoot("STUDENT_INFO")]
public class StudentContainer()
{
[XmlArrayItem("STUDENT")]
public List Stu = new List();
public void Save(string path)
{
var serializer = new XmlSerializer(typeof(StudentContainer));
using(var stream = new FileStream(path, FileMode.Create))
{
serializer.Serialize(stream, this);
}
}
public static StudentContainer Load(string path)
{
var serializer = new XmlSerializer(typeof(StudentContainer));
using(var stream = new FileStream(path, FileMode.Open))
{
return serializer.Deserialize(stream) as StudentContainer;
}
}
//Loads the xml directly from the given string. Useful in combination with www.text.
public static StudentContainer LoadFromText(string text)
{
var serializer = new XmlSerializer(typeof(StudentContainer));
return serializer.Deserialize(new StringReader(text)) as StudentContainer;
}
}
然后使用列表进行迭代。可以使用.Name或.Age。我猜你已经知道如何做了。
**UPDATE**
//To use this
StudentContainer myStudents;
myStudents = DictionaryList.Load("C: <- your path");
