实现IConfigurationSectionHandler接口读取配置文件

 

Code
namespace MySpace.SectionHandler
{
  public class ConfigItem
  {
        string _connType;
        string _cmdType;
        string _adapterType;
        string _readerType;
        public string ConnType
        {
            get { return _connType; }
            set { _connType = value; }
        }
        public string CmdType
        {
            get { return _cmdType; }
            set { _cmdType = value; }
        }
        public string AdapterType
        {
            get { return _adapterType; }
            set { _adapterType = value; }
        }
        public string ReaderType
        {
            get { return _readerType; }
            set { _readerType = value; }
        }
  }
  public class CustomSection:IConfigurationSectionHandler
{
  public object Create(object parent,object configContext,System.Xml.Node section)
  {
     List<ConfigItem> list=new List<ConfigItem>();
     if(parent!=null){list=(List<ConfigItem>)parent;}
     foreach(XmlNode node in section.ChildNodes)
     {
        if(node.Attributes!=null)
        {
            ConfigItem item = new ConfigItem();
            item.AdapterType = node.Attributes["adapterType"].Value;
            item.CmdType = node.Attributes["cmdType"].Value;
            item.ConnType = node.Attributes["connType"].Value;
            item.ReaderType = node.Attributes["readerType"].Value;
                    list.Add(item); 
        }
     }
     return list;
  }
}
}

 

相应的配置文件如下:

 

Code
  <configSections>
    <section name="conn" type="MySapce.SectionHandler.CustomSection,CustomSection"/>
  </configSections>
  <conn>
    <myStr adapterType="SqlDataAdapter" cmdType="SqlCommand" connType="SqlConnection" readerType="SqlDataReader"/>
  </conn>

 

页面获取配置信息

 

Code
        List<MySapce.SectionHandler.ConfigItem> list = ConfigurationManager.GetSection("conn") as List<ConfigItem>;
        Response.Write(list.Count);
        foreach (ConfigItem item in list)
        {
            Response.Write(item.CmdType);
        }
