读书笔记：《亮剑 .Net》——将类转化为XML并保存已经去读后反序列化为类对象

简历一个可序列化的类

/// <summary>
/// 配置的Modul类，即：保存的配置项(可以自定义成自己的项)
/// 注意相关属性的类型与[XmlElement]
/// </summary>
public class ModuleSettings
{
private string server;
private string username;
private string password;
private string database;

[XmlElement]
public string Server
{
set { server = value; }
get { return server; }
}
[XmlElement]
public string UserName
{
set { username = value; }
get { return username; }
}
[XmlElement]
public string Password
{
set { password = value; }
get { return password; }
}
[XmlElement]
public string Database
{
set { database = value; }
get { return database; }
}
}

序列化后保存

public static void SaveSettings(ModuleSettings data)
{
string fileName = HttpContext.Current.Server.MapPath(GetSettingsFile());
XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));

// serialize the object
FileStream fs = new FileStream(fileName, FileMode.Create);
serializer.Serialize(fs, data);
fs.Close();
}

读取后反序列化

//得到配置项对象实例信息
public static ModuleSettings GetSettings()
{
XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));
try
{
//从文件取
string fileName = HttpContext.Current.Server.MapPath(GetSettingsFile());
FileStream fs = new FileStream(fileName, FileMode.Open);
return data = (ModuleSettings)serializer.Deserialize(fs);//反序列化
fs.Close();
}
catch (System.IO.FileNotFoundException)
{
//如果文件不存在，则返回一个空对象
return data = null
}
}
