使用IConfigurationSectionHandler在web.config中增加自定义配置

2. 实现IConfigurationSectionHandler接口：SiteSettingHandler   

namespace Tristan.SeeCustomConfig {    public class SiteSettingHandler : IConfigurationSectionHandler {        #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 };        }

        #endregion    }}

3. 在web.config中进行配置    在<configSections></configSections>里面增加一个节点：<section name="siteSetting" type="Tristan.SeeCustomConfig.SiteSettingHandler"/>

    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<configuration><configuration>里面增加一段xml：<siteSetting>        <siteName>遇见未来</siteName>        <siteVersion>1.0</siteVersion>    <closed>false</closed>    </siteSetting>

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   

namespace Tristan.SeeCustomConfig {    public class SiteSettingHandler : IConfigurationSectionHandler {        #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    <siteSetting type="Tristan.SeeCustomConfig.SiteSetting">        <siteName>遇见未来</siteName>        <siteVersion>1.0</siteVersion>    <closed>false</closed>    </siteSetting>

4. 再来看看    不修改测试代码，得到了一样的效果 ：）
