使用IConfigurationSectionHandler在web.config中增加自定义配置_[Asp.Net教程]

一. 场景
这里仅举一个简单应用的例子，我希望在web.config里面增加网站的基本信息，如：网站名称，网站版本号，是否将网站暂时关闭等。
二. 基本实现方法
1. 定义配置节点对应的类：SiteSetting
代码片段：

namespace Tristan.SeeCustomConfig {
public class SiteSetting {
public string SiteName { get; set; }
public string SiteVersion { get; set; }
public bool Closed { get; set; }
}
}

Code
namespace Tristan.SeeCustomConfig {
public class SiteSettingHandler : IConfigurationSectionHandler {
IConfigurationSectionHandler Members#region IConfigurationSectionHandler Members

public object Create(object parent, object configContext, System.Xml.XmlNode section) {
string siteName = section.SelectSingleNode("siteName").InnerText;
string siteVersiton = section.SelectSingleNode("siteVersion").InnerText;
bool closed = Convert.ToBoolean(section.SelectSingleNode("closed").InnerText);
return new SiteSetting() { SiteName = siteName, SiteVersion = siteVersiton };
}

name：指定我们将要增加的节点名为"siteSetting"，接下来会使用它来编写配置节点
type：指定处理这个配置节点的handler，这个类，我们在前面已经把代码实现了
然后在里面增加一段xml：

false

4. 看看效果吧
随便建一个页面在后台代码里写几行代码做个测试：

namespace Tristan.SeeCustomConfig {
public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
SiteSetting site = ConfigurationManager.GetSection("siteSetting") as SiteSetting;
Response.Write(site.SiteName + "," + site.SiteVersion + "," + site.Closed.ToString());
}
}
}
运行，可以看到，我们在web.config中的信息被write出来了。：）
三. 使用XML反序列化
1. 修改SiteSetting

namespace Tristan.SeeCustomConfig {

[Serializable]
[XmlRoot("siteSetting")]
public class SiteSetting {
[XmlElement("siteName",typeof(string))]
public string SiteName { get; set; }

[XmlElement("siteVersion",typeof(string))]
public string SiteVersion { get; set; }

[XmlElement("closed",typeof(Boolean))]
public bool Closed { get; set; }
}
}

2. 修改SiteSettingHandler

Code
namespace Tristan.SeeCustomConfig {
public class SiteSettingHandler : IConfigurationSectionHandler {
IConfigurationSectionHandler Members#region IConfigurationSectionHandler Members

public object Create(object parent, object configContext, System.Xml.XmlNode section) {
//string siteName = section.SelectSingleNode("siteName").InnerText;
//string siteVersiton = section.SelectSingleNode("siteVersion").InnerText;
//bool closed = Convert.ToBoolean(section.SelectSingleNode("closed").InnerText);
//return new SiteSetting() { SiteName = siteName, SiteVersion = siteVersiton };

string typeName = ((XmlElement)section).GetAttribute("type");
XmlSerializer xz = new XmlSerializer(Type.GetType(typeName));
using (StringReader sr = new StringReader(section.OuterXml)) {
return xz.Deserialize(sr);
}
}

#endregion
}
}

3. 修改web.config中的配置

false

4. 再来看看
不修改测试代码，得到了一样的效果：）
