自定义XML配置文件的操作类

自定义XML配置文件的操作类

xml配置文件：

<?xml version="1.0"?>

<ModuleSettings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<DataSource>fujian</DataSource>

<Uid>fujian_zyz</Uid>

<Password>fujian_sql_zyz</Password>

<ShowLogin>false</ShowLogin>

</ModuleSettings>

操作类的实现：

using System;

using System.IO;

using System.Web;

using System.Text;

using System.Xml.Serialization;

using System.Xml;

namespace LTPTOOL

{

#region 配置对象模型类

/// <summary>

/// 李天平

/// 2004.3

/// 配置的modul类（注意相关属性的类型与[XmlElement]）

/// use:ModuleSettings settings=ModuleConfig.GetSettings();

/// </summary>

public class ModuleSettings

{

private string datasource;

private string uid;

private string password;

private bool showlogin;

[XmlElement]

public string DataSource

{

set{ datasource=value; }

get{ return datasource; }

}

[XmlElement]

public string Uid

{

set{ uid=value; }

get{ return uid; }

}

[XmlElement]

public string Password

{

set{ password=value; }

get{ return password; }

}

[XmlElement]

public bool ShowLogin

{

set{ showlogin=value; }

get{ return showlogin; }

}

}

#endregion

#region 配置的操作类ModuleConfig

/// <summary>

/// 配置的操作类ModuleConfig。

/// </summary>

public class ModuleConfig

{

public static ModuleSettings GetSettings()

{

ModuleSettings data = null;

XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));

try

{

string fileName = "db.config";

FileStream fs = new FileStream(fileName, FileMode.Open);

data = (ModuleSettings)serializer.Deserialize(fs);

fs.Close();

}

catch

{

data = new ModuleSettings();

}

return data;

}

public static void SaveSettings(ModuleSettings data)

{

string fileName = "db.config";

XmlSerializer serializer = new XmlSerializer (typeof(ModuleSettings));

// serialize the object

FileStream fs = new FileStream(fileName, FileMode.Create);

serializer.Serialize(fs, data);

fs.Close();

}

#endregion

}

}

得到配置文件的详细信息；

ModuleSettings settings=ModuleConfig.GetSettings();

txtServer.Text=settings.DataSource;

txtUser.Text=settings.Uid;

txtPass.Text=settings.Password;

保存修改：

settings.DataSource=txtServer.Text;

ModuleConfig.SaveSettings(settings);

对于扩展配置也非常方便，只需修改ModuleSettings的对象模型和ModuleConfig.中的文件名就可以用到任何其他配置文件的操作中。
